1.2 Moving Mechanism
The moving mechanism is made of stainless steel
and is permanently installed on the tank. It consists
of three arms with the following designations:
A = horizontal arm, fixed,
B = moving vertical arm and
C = moving horizontal arm.
The moving mechanism is suitable for both horizontal and vertical radiation. Holding devices for detectors to move in the field are screwed to the slider of
the C-arm. The slider and the arms are moved by
stepper motors that permit a minimum step width of
0.1 mm. The reproducibility of the geometric positioning is also ± 0.1 mm.
The moving range limits can be adjusted for each
axis and stored in the TBA CONTROL UNIT to ensure that the detector does not hit the Perspex
walls.
The components of the moving mechanism, particularly the guides and moving parts, are not adversely
affected by water. Bending or contortion due to
water absorption or corrosion is thus excluded.
CAUTION
Improper handling.
Risk of injury!
Do not reach into the Perspex tank while the
moving mechanism is working.
Pay attention that hairs or cloths of the user and
other persons involved do not touch the rotating
spindle.

1.3 Positioning Device
MP3
Therapy Beam Analyzer
Operating Manual – The Components of the MP3 System
The positioning device allows the Perspex tank to
be aligned, using the light beam diaphragm, the
laser system and the lines on the walls of the tank.
The positioning device has three adjustable legs
with hand wheels that allow the height to be adjusted by ± 10 mm. Additionally, the three adjusting
screws allow the tank to be adjusted horizontally by
± 10 mm, or by approx. 1° on a vertical axis (microadjustment). A mechanism allows the tank to be
rotated by 45°or 90° (refer to
rotation).
Horizontal alignment of the tank is easy when it is
filled to the horizontal lines and the water surface is
used as a level.
The tank is screwed on to the positioning device
(see section

Therapy Beam Analyzer
Operating Manual – The Components of the MP3 System
1.6 TBA CONTROL UNIT and TBA CONTROL PENDANT
The MP3 system is operated via a TBA CONTROL
UNIT and a TBA CONTROL PENDANT.
The TBA CONTROL UNIT is an interface that connects the MP3 water phantom to the PC. It supplies
the power for the stepper motors and controls the
detector movement.
The TBA CONTROL PENDANT can be connected
either to the TBA CONTROL UNIT or to the junction
box (at the Perspex tank). The TBA CONTROL
PENDANT indicates the detector coordinates A, B
and C and allows the detector to be moved at two
different speeds (10 mm/s and 50 mm/s). Additionally, the limits for the detector movement, the null
point in the central beam and the reference points
can be determined via the TBA CONTROL
PENDANT. Please note that some of the TBA
CONTROL PENDANT functions are available only
when it is directly connected to the junction box at
the Perspex tank (refer to the user manual of the
TBA CONTROL PENDANT). Therefore it is recommended to connect the TBA CONTROL
PENDANT to the junction box.
1.7 System Enhancement
The following equipment can be added to the MP3
system. The corresponding measuring programs
are already implemented in the MEPHYSTO software.
1.7.1 TPR Option
The TPR option permits automatic measurement of
the tissue-phantom ratios. While the sourcedetector distance is fixed, the water level changes.
For this measurement, the water reservoir is connected to the junction box at the Perspex tank and
a liquid level switch with holder and connection
cable is installed. The corresponding measuring
program is already implemented in the MEPHYSTO
software.
1.7.2 Linear Array LA48
The Linear Array LA48 is used for the measurement
of profiles, predominantly profiles of dynamic fields.
The LA48 has 47 ion chambers. The measurement
is performed in the water-filled MP3 Perspex tank.
For the measurement, you also need a multichannel therapy dosemeter MULTIDOS with ME48.
For further information on the TBA CONTROL UNIT
and on the TBA CONTROL PENDANT refer to the
corresponding user manuals.

3.3 Filling with Water
MP3
Therapy Beam Analyzer
3.3.2 Emptying the Perspex Tank
3.3.1 Filling the Perspex Tank
Before filling the Perspex tank, ensure that the water and the tank both have room temperature.
• Filling with distilled water (see Note for water
quality).
• It is recommended first to fill the Perspex tank to
the maximum level and then to pump the water
into the water reservoir. This way, the tank will
never overflow, because the water reservoir has
a greater capacity.
It may prove useful to fill some more water into the
water reservoir to prevent bubbles and strong
movements of the water, when the water reservoir
is almost empty and the pump continues to operate
for a few seconds. The water inlet is located below
the small flap at the top of the water reservoir. If the
water reservoir was filled with more water, the user
must be ready to turn off the pump when the Perspex tank is full. The pump can be turned off with
the OFF button on the control panel of the water
reservoir.
NOTE
After use, the Perspex tank should be emptied to
prevent deformation of the walls and undue
stress on the seams.
The MP3 water reservoir is used to pump the water
out of the Perspex tank. The inclination required to
completely drain the Perspex tank can be attained
by adjusting one of the screw feet accordingly. Do
not tilt the tank manually. If you wish to empty the
water reservoir, you can pump the water via the
locking nipple L643011.
The automatic switch-off prevents the pump from
running dry, should it be turned on while the water
reservoir is empty.
NOTE
Use only distilled water to fill the system.
Add an anti-corrosion fluid recommended by
PTW-Freiburg (PTW-Nr. L999010) to one filling.
Follow the instructions of the manufacturer for
the dosage of the anti-corrosion fluid.
The anti-corrosion fluid has no effect on the absorption and scatter characteristics of high-energy radiation.

Service Manual – Cleaning
8.5 Moving Mechanism
Clean the cables as follows:
• Disconnect the cables from the devices, pulling
on the plug, not on the cable.
• For cleaning, rub the cables down with a cloth
moistened with soap water or with disinfectant.
• Never immerse the cable in liquid!
8.3 Connectors
Do not immerse the connectors in liquids! Do not let
liquid enter the connectors.
The connectors must not become dirty. Clean the
connectors only with a soft brush. Do not blow into
the connector.
8.4 Perspex Tank
The MP3 water reservoir is used to pump the water
out of the Perspex tank. The inclination of the tank
that is necessary to complete empty it can be
achieved by adjusting one of the screw feet. Do not
tilt the tank manually.
The supporting profile and the angle are adjusted
by PTW-Freiburg. Do not remove them.
The shafts and toothed wheels of the moving
mechanism should be lubricated with the supplied
grease at intervals of 1 to 2 years or when necessary (use small amount of grease only!).
8.6 Cleaning Water Reservoir
Usually the water reservoir does not need to be
cleaned for a long time. There are two inspection
fittings at the top of the water reservoir through
which the inside can be accessed for cleaning.
These apertures are located at the bottom of the
two storage compartments. They are opened by
removing the cap and closed by reinstalling it.
For cleaning, use a mild cleaning agent suitable for
plastic material or soap water.
A drain plug (SW32) is located at the bottom of the
water reservoir. Open this plug to drain the dirty
water.
After cleaning, the tank must be thoroughly rinsed
to remove all remains of the cleaning agent. Eventually, reinstall the drain plug. Close the two caps at
the top of the tank and tighten the screws evenly,
but not fully.
For cleaning, use a mild cleaning agent suitable for
plastic material or soap water.
After cleaning, thoroughly remove all remains of the
cleaning agent.
You should coat the Perspex tank for storage with
the delivered cover.
