Chapter 2 – Installation

This chapter describes the steps required to set up the CCX 70 so that the water cooling is

ready for activation. You should also refer to the source manual for details of the vacuum

installation and bakeout, as well as any warnings and special requirements for your source.

Installation involves the following steps:

 Fitting the unit in a rack.
 Water connections.

There is also some information about the interlock conditions that need to be fulfilled before

the instrument can be activated.

2.1 Rac k Mou ntin g

The CCX 70 fits into a standard 19" rack. You should observe the following points:
 Mount the CCX 70 at the bottom of the 19" rack. In the event of a water leak, no other elec-

tronic units will be damaged.

 Fit the unit into the same rack as the UXC 1000 for ease of connection.
 Connect a hose to the Water Drain outlet on the rear panel in case of a water leak inside

the unit. Lead the outflow of this hose away from the rack.

 Arrange the water hoses and the grounding cable so that the CCX 70 can be pulled out of

the rack for service purposes.

2.2 Connections and Interl ocks

For details of the electrical connections, please refer to the manual for your source.

The XR 50 is protected by a number of interlocks, most of which are handled by the CCX 70. The

interlock status is sent to the UXC 1000, which will only operate if all interlocks are safe. In the

event of an interlock trip, the UXC 1000 will show an error message detailing the problem.

It is helpful to know what these interlocks are when setting up the source:
 Water—there is a flow meter and temperature sensor inside the CCX 70 to monitor the

water flow and temperature. The signals are sent to the UXC 1000. If the values fall out-

side the limits set in the UXC 1000, source operation is stopped.

 HV—the HVcable must be plugged into the back of the UXC 1000 before the high voltage

can be activated in the UXC 1000.

 Protection cap—there is a microswitch on the protection cap that is closed when the

cap is correctly fitted. The high voltage can only be activated when this switch is closed.

CCX 70 V1.1 | 29 April 2016

6

 Internal water detector—stops operation in the event of a water leak inside the CCX

70.

 Front panel maintenance cover—this needs to be closed correctly before operation

can occur.

 The UXC 1000 can also be connected to an interlock sensor, e.g. a pressure measurement

gauge. If this interlock is not in use, it needs to be bridged with a terminator (supplied).

If the XR 50 is correctly connected and the conditions described in this chapter are met, these

interlocks are safe and the XR 50 can be operated.

Caution!

Do not attempt to defeat the interlocks. Death, serious injury or severe dam-

age to the source can result if the interlocks are overridden.

2.3 Wa ter Coolin g

The XR 50 has the following requirements for the cooling water:

 Flow rate: >2.5 l/min
 Temperature: 20 ºC

There are a number of other important additional considerations for cooling water. These guar-

antee a long lifetime of the source as well as describing possible problems that might appear

during operation. Please read the chapter "Water Supply" on page 11 for a complete descrip-

tion of the water requirements.

Caution!

If several items of equipment share the cooling water supply (pumps, etc.),

make sure that the pressure and temperature is adequate and fulfills the
cooling requirements for all instruments.

The cooling requirements vary according to the source. The XR 50 and XR50 M have two cool-

ing circuits:

 Anode. This circuit is made when you fit the protection cap over the source.
 Head. The connectors are on the body of the source, near the system flange.

The XR-MF only has a cooling circuit for the anode. Nevertheless, you should read the section

"Head Cooling Circuit" on page 8 as it contains useful information about connecting a closed-cir-

cuit chiller. Please also see the XR-MF manual for more details.

CCX 70 V1.1 | 29 April 2016

2.3.1 Fitting the Protection Cap

During operation, the top flange of the XR 50 is at high voltage. For safety reasons, a protection

cap prevents access to this flange. A safety interlock switch mounted on the side of the cap is

closed when the cap is correctly in position. The high voltage can only be activated when this

switch is closed.

The picture below shows the source head before fitting the protection cap. Note the position of

the safety switch contact (marked with a green box) . You need to use this for orientation of the

protection cap.

Note

Depending on the model, your source may appear to be different to that shown in the picture.

This does not affect the procedure for fitting the cap.

7

To fit the protection cap:

1. Fit the support frame over the source flange and tighten the three grub screws to fix it into

place. This supports the weight of the conduit while connecting the water hoses.

2. Fit the water hoses onto the cooling pipes, making sure to observe the correct flow dir-

ection. The hoses and pipes are labeled with arrows. The center (longer) pipe is for water

flowing into the source.

Note

The high voltage connections are also made when you fit the hoses.

CCX 70 V1.1 | 29 April 2016

8

3. Slide the protection cap over the frame so that the contact fits into the safety switch.

4. Secure the protection cap with the three screws around the side of the cap.

Removing the protection cap is the reverse of the above. Note the following points:
 When pulling the cap away from the head, take care not to strain the cable for the safety

switch interlock.

 Always disconnect the water connectors before removing the support frame. Without the

frame, the weight of the conduit can damage the water hoses.

2.3.2 Head Cooling Circuit

SPECS recommends a water chiller to supply water to both cooling circuits on the source. Fig-

ure 1 shows the connection scheme for the water cooling.

The Chiller output on the CCX 70 supplies a +24 VDC signal when the cooling is activated. This

switches the power supply to the water chiller.

If you are not using a water chiller, e.g. tap water or another installed water supply, the con-

nection scheme is essentially the same, with your water supply in the place of the water chiller.

Chapter 3 – Water Supply

Adequate water cooling is critical for the reliable operation of the X-ray source. Failure to

provide suitable cooling can lead to unstable operation and severely reduced lifetime of the

source.

Caution!

Experience shows that a common reason for equipment failure is inad-

equate cooling. It is vital that you observe the information in this chapter con-

cerning the properties of the cooling water.

The following topics are particularly important for the cooling water:

 Make sure the water is clean and free of contaminants.
 Prevent biological activity in the water system.
 Ensure that the water pressure and flow rate is correct.
 Maintain the water temperature within the correct operating range.
 Check the source frequently for signs of corrosion.
 Make sure the water current is within the accepted range for stable operation.

11

This chapter describes the above points in more detail. Please also refer to "Cleaning" on page

23 for details about the regular maintenance procedures. It is also necessary to clean the

source frequently to ensure the quality of the cooling water.

3.1 Qua lity

It is essential to use clean water for cooling:

 Do not use polluted or dyed water.
 If there are particles in your water supply, fit a filter.
 Do not use salt water, as it will promote corrosion.

Distilled water is not advisable, as it can cause corrosion in the chiller. Its low conductivity also

means that there is a low water current, leading to unstable operation.

Clean tap water is recommended for the cooling water. If you have doubts about the quality of

your mains water supply, you should use distilled (or deionized) water and add bottled mineral

water until the water current reaches the normal range (2…10 mA).

CCX 70 V1.1 | 29 April 2016

12

Caution!

Contaminants in the water supply can reduce the cooling efficiency, leading

to increased operating temperatures. This can cause damage to the source.

Refer to "Cleaning" on page 23 for details about regular checks and cleaning

procedures to avoid the accumulation of contaminants.

Note that particles and chemical compounds will be formed in solution by electrochemical pro-

cesses. These are deposited as sediments. For this reason, you need to clean the filters and

check the water quality periodically, replacing water as necessary.

3.2 Pr eventin g Bi ologi cal Activity

It is vital to hinder the growth of microorganisms in the cooling water. These can:

 Promote corrosion inside the source.
 Cause blockages and reduced water flow.
 Create insulating layers, reducing the effectiveness of the cooling water.

3.2.1 Algicide

SPECS recommends the use of an algicide to prevent the growth of algae, bacteria and fungus

in the cooling water. This is essential when using a closed circuit water chiller. Please see the

water chiller documentation for more details about using an algicide.

Warning—Harmful!

Avoid contact with anti-algeon. Irritations of skin and mucosa are possible.

3.2.2 Water Hoses

SPECS supplies dark, opaque hoses with the CCX 70. These prevent light from reaching the

water and thereby reduce biological activity.

Note

If the X-ray source is out of use for long periods of time, remove the hoses and blow the water

out of the source. This will avoid possible sedimentation effects.

3.3 Pr essu re an d Flow R ate

The CCX 70 contains a pressure meter and a flow meter to monitor the static water pressure of

the inlet line as well as the rate of water flow through the system. The water inlet valve is con-

trolled by the UXC 1000. The reading of the pressure meter is read by the CCX 70 and can be

displayed by the UXC 1000.

sure need to be checked. In this case, water cooling for the instruments needs to be set up in a

shunt arrangement. Make sure that all instruments receive adequate cooling.

Caution!

The minimum flow rate for the XR 50 is 2.5 l/min. Do not operate the source

with a lower flow rate, as severe damage can result.

3.4 Temperatur e

The cooling water temperature is important for reliable operation. The recommended water

temperature range is 15–22 ºC, with a nominal temperature of 20 ºC.

You should avoid water temperatures outside this range:
 Lower temperatures can easily cause condensation on the source (depending on the dew

point), leading to flashovers of the anode HV to ground.

 Higher temperature may result in overheating of the source, leading to evaporation of the

anode or—in the worst case—a cracked anode with a water leak into the chamber.

The water temperature is displayed in the Chiller menu of the UXC 1000. You can also set the

lower and upper temperature limits in this menu.

13

3.5 Wa ter Cur ren t

Figure 2 shows the principle of operation of an X-ray source. Of particular interest in this sec-

tion is the water resistance. During operation, the anode is at a potential of up to +15 kV. Due to

the finite conductivity of the anode cooling water, there is also a current that flows through the

water to ground.

UF = Filament voltage
IF = Filament current
IE = Emitter current
IA = Anode current
IW = Water current
UA = Anode voltage

Figure 2: Operationof X-ray source

For stable operation, the water current should be in the range 2…10 mA. You can monitor the

water current in the Chiller menu of the UXC 1000.

CCX 70 V1.1 | 29 April 2016

14

Water current to o lo w

If the water current is too low, electrochemical attacks at the anode can occur.

The easiest way to reduce the water resistance is to add a small amount of tap water or min-

eral water to the cooling water. Alternatively, a small quantity of copper salt (sulfate, nitrate)

can provide the necessary conductivity.

Water current to o high

The power delivered by the source is given by the anode current and anode voltage. However,

the power supply is limited by the amount of emission current it can deliver. If too much current

is being lost as water current, the power output from the source drops.

In order to reduce the water current, you should add deionized or distilled water. If you are

using tap water and the water current is too high, you need to change the water supply—a

closed circuit system offers the best solution in this case.

High water current can also be caused by contaminants in the cooling water. In this case, per-

form some cleaning cycles with tap water to wash the cooler and the water lines, then refill the

cooler with deionized or distilled water.

CCX 70 V1.1 | 29 April 2016

Chapter 4 – Operation

The CCX 70 is controlled by the UXC 1000. In addition to switching the water cooling on and off,

the UXC 1000 can display the status of the CCX 70 and allows you to set parameters such as

the water flow and temperature limits.

This chapter contains the basic information relevant to the CCX 70. For more information,

please refer to the UXC 1000 manual.

4.1 Swi tc hi ng O n

There is no power switch on the CCX 70—it is switched on by the UXC 1000.

Switching the water cooling on and off is also controlled by the UXC 1000. When you activate a

preset, a valve inside the CCX 70 opens, allowing water flow through the cooling circuits. If you

have a water chiller, this will also be switched on.

Most of these problems are related to the interlock conditions being satisfied, or to the correct

flow of water in the circuits, as described in more detail in the following sections.

CCX 70 V1.1 | 29 April 2016

20

5.1 Wa ter Interl ock Pr obl ems

With first operation after connecting, some air bubbles may pass through the system. These

will cause the interlock to trip. In this case, switch on a few times until all the bubbles have

gone.

The UXC 1000 will report any problems with the water interlock. The Chiller menu shows the

current status of the CCX 70. You should check the following points:

 Water flow direction from between the CCX 70 and water supply.
 Make sure the service panel on the front panel is closed. There is an interlock switch on

this panel.

 Examine the water hoses between the CCX 70 and the source. Make sure there are no

kinks or loose connections.

Also check the temperature of the water. This should be ~20 °C. If it is not within the limits set

in the UXC 1000, check your water supply or chiller unit.

Caution!

Do not defeat the water interlocks. Severe damage to the source will result

during operation and the warranty will be voided.

5.2 Wa ter Fl ow Problems

If it appears that the water flow is blocked or significantly reduced, you can use the water

bypass loop supplied with the source to try to locate the bottleneck. Since there are two cooling

circuits in the source, there are two potential places within the source itself where blockages

might exist.

Figure 5:Water bypass loop

To check the head cooling circuit:

1. Remove the two hoses from the head cooling circuit, as indicated in the picture below.

2. Connect the bypass loop between the two hoses.

3. Switch on the water cooling circuit and check the water flow.

An o d e co o l ing ci rcuit

If you have removed the water hoses for the head cooling circuit, as in the description above, fit

them back into place.

To check the anode cooling circuit:

1. Remove the protection cap from the source and detach the connectors from the anode

flange.

2. Fit the bypass hose to the anode connectors in order to complete the circuit, as indicated in

the picture below.

Over time, small particles will appear in the water supply due to electrochemical reactions. The

CCX 70 contains internal filters as well as an external filter to the water supply. Over time, con-

taminants will build up on these filters and connections. Clean these parts occasionally to

ensure adequate water flow and to prevent contaminants from damaging the source.

These maintenance steps involve the following tasks:

 Removing the internal filters and cleaning them.
 Cleaning the anode connections.
 Cleaning the external filter.
 Checking the condition of the hoses.

These procedures should be performed every 100–200 working hours. Observe the require-

ments and advice contained in Chapter 3 – and check the water quality regularly.
These cleaning operations should be performed approximately every year.

In the event of severe contamination, you will need to chemically clean the cooling system, as

described in "Cleaning the Water Cooling Circuit" on page 26.

6.1 Cleanin g the In terna l Fi lters

There are a set of internal filters that collect sediment from the water. A service area on the

front panel of the CCX 70 provides easy access to these filters without it being necessary to

open the case.

Caution!

There is a water leak sensor inside the CCX 70. If any water leaks into the

interior of the unit, it may disable the unit.

Note

The service panel contains an interlock switch that prevents operation when it is open.

To clean the internal filters:

1. Switch off the UXC 1000.

2. Undo the two screws retaining the service area on the front panel and let the panel down

on its hinges.

3. Remove the two cathode socket head cap screws and the two internal particle filters.

4. Clean the following items:

 Filters
 Cathode screws
 Cathode PTFEblock

5. Reassemble the cathode block and close the service area panel.

6. Run the water for a short time, then check for leaks. Remember that this panel is inter-

locked.

6.2 Cleanin g the An ode Con nec ti ons

In addition to the internal filters, contaminants can also build up on the anode water cooling

connections.

Inspect the anode before bakeout or as part of the routine maintenance, whichever is sooner.

Note

A spare set of HVelectrodes is included in the delivery. If you suspect that the anode is leaking

or corroded, replace the electrodes. See the source manual for details of how to change the

anode.

To clean the anode connections:

1. Switch off the source and allow it to cool down.

2. Remove the protection cap from the source (see "Fitting the Protection Cap" on page 7)

3. Remove the quick hose connector.

4. Clean the hose connectors and anode tubes on the source using tissues or cotton wool tips

and water.

CCX 70 V1.1 | 29 April 2016

5. Reassemble the connectors. If necessary, wrap

PTFE tape around the connector to ensure a

water-tight seal.

6. After replacing the protection cap, allow water to run through the circuit for a few minutes,

then remove the cap to confirm that the connections are not leaking (i.e. no water drops or

moisture on the connectors).

7. Fit the protection cap. The source is ready for use.

25

6.3 Cleanin g the E xtern al Filter

For safe operation of the flow meter and to avoid blocking or reducing the water flow by

particles, an external particle filter is attached to the water input. This is easy to access and

clean and should also be cleaned as part of the routine maintenance procedure.

Note

If you remove the filter from the hose, observe the flow direction when reconnecting.

To clean the external filter:

1. Switch off the water cooling supply.

2. Unscrew the cover on the blue filter on the water input line.

3. Remove the white filter.

Figure 7:Removing the external filter

4. Wash the filter with tap water.

5. Replace the filter and screw the cover back into place.

6.4 Cleanin g the Water Cooli ng C ir cui t

Very long working periods or poor water quality can cause a build up of contamination in the

cooling circuit. These deposits are visible in the tubes inside the CCX 70.

If you have a closed circuit water chiller, you can clean the whole circuit by pumping a citric acid

solution through the system.

Warning—Harmful!

Citric acid (2-hydroxypropane-1,2,3-tricarboxylic acid) is a skin and eye irrit-

ant.
CAS-number 5949-29-1.

To clean the water cooling circuit:

1. Dissolve ~700 g of citric acid in water and add this solution to the water chiller.

2. Switch off the cooling for the water chiller, leaving the water pumps running.

3. Start water flow through the source by selecting the Chiller menu and pressing Start.

4. Allow the citric acid solution to run through the system for 12 hours. During this time, the

water temperature will rise slightly—this is desirable, as it increases the reactivity accord-

ingly.

5. Drain the water chiller and refill it with tap water. Allow the water to run through the source

for five minutes to rinse away the acid.

6. Repeat step 5 twice.

7. Refill the water chiller with distilled or deionized water.

8. Switch on the cooling and pump the water through the source.

CCX 70 V1.1 | 29 April 2016

For exceptionally contaminated systems, you might try any or all of the following:

 Use a saturated solution of citric acid (~750 g/l of water).
 Warm the water with a thermostat up to a temperature of ~50–60 ºC.
 Run the citric acid solution through the source for up to 24 hours.

Chapter 7 – Technical Details

This chapter contains an overview of the features on the front and rear panels of the CCX 70,

including pin assignments of the electrical connectors. It also contains information about the

internal components and construction of the instrument.

7.1 Fr on t Panel

There is no power switch on the front panel of the CCX 70—power is controlled by the UXC

1000.

The only feature on the front panel is the service area. This is held in place by two screws. The

service area opens on hinges, providing easy access to the cathode filters. The cleaning pro-

cedure is described in "Cleaning the Internal Filters" on page 23. There is a switch fitted to the

panel which acts as an interlock. The power is switched off when the panel is open.

29

Figure 8:Front panel

7.2 Rear Pan el

The rear panel is fitted with all electrical and water connections, as well as a water drain. The

figure and sections below describe the features. Pin assignments of the connectors are also

included.

Figure 9: Rear panel

HV I n

This cable connects to the HVOut on the UXC 1000. It routes the voltage with the anode cooling

water through the Anode conduit.

CCX 70 V1.1 | 29 April 2016

30

An o d e

This plastic covered conduit carries the cooling water for the anode as well as the anode

voltage. At the source end of the conduit, there is a protection cap so that no exposed parts of

the source are at high voltage during operation. See "Fitting the Protection Cap" on page 7 for

more information.

Interlo ck

The Interlock connector (6-pin M8) provides power for the CCX 70, as well as carrying the inter-

lock status and the communication interface with the UXC 1000 HVUnit.

Chiller

The CCX 70. is able to control a water chiller. The Chiller output provides a 24 V signal that can

switches power to the water chiller. An example of the wiring scheme is shown in "Head Cool-

ing Circuit" on page 8

Link

The Link connector is useful if your system contains two or more CCX 70 units.

It provides a connection between two CCX 70 units and makes sure that only one CCX 70 is able

to control a closed circuit water cooler at any time. If more than one system simultaneously

accesses a cooling circuit, the water pressure will drop, potentially below the pressure required

for operation, causing one or both intruments to switch off.

Figure 11 shows the wiring scheme for two CCX 70 units. Each is connected to its own UXC

1000. The Chiller output on one CCX 70 is then connected to the Link on the other.

Water drain

This tube is connected to the internal water tank and allows water to escape in the event of an

internal water leak. You should attach a hose which leads away from the electronic racks.

7.3 Block Di agr am

The diagram below shows the components used in the CCX 70.

7.4 Interi or Details

The water connections inside the CCX 70 are contained inside a water tank which prevents

water leakage into the rest of the unit. There is a water sensor on the bottom of the tank that

shuts down the water supply in the event of a leak.

Figure 13 shows the main internal features of the CCX 70. The inset shows the water tank with

the cover removed.

A water drain at the rear allows water to flow out of the unit. You should attach the water drain

to a hose to lead water away from electronics racks.

To open the water tank:

1. Remove the four screws marked with green circles in Figure 13. For most purposes, you

can leave the earthing straps attached. If you need to remove these, remember to replace

them when refitting the covers.

2. Slide the covers away from the edge of the case and lift them away.
