NICOL X-Ray Beam Limiting Device Introduction and Technical Data

1 INTRODUCTION AND TECHNICAL DATA

1.1 INTRODUCTION

This X-Ray Beam Limiting Device (BLD) is suitable for:

• RAD application 9896 010 2216. successor of 9896 010 22001

• RF applications with light and ruler 9896 010 2217. successor of 9896 010 22011

• RF applications as above plus filter and iris 9896 010 2223. successor of 9896 010 22091

• RF applications 9896 010 2224. successor of 9896 010 22101

The BLD, contains the following functions:

• Rectangular collimation, using rectangular shutters (main-, backup- and near focus shutters)

• Non rectangular collimation, using rectangular and iris shutters (iris on 9896 010 2223. and

9896 010 2224. only)

• Remotely controlled spectral filter (except for 9896 010 2217.)

• Light source (including field indication plate with crossed lines, fan and light ON button) for

simulating the X-Ray Field

• Electronic Ruler (9896 010 2216.) for automatic measuring the Source Image distance

• Mechanical Ruler (9896 010 2217. and 9896 010 2223. and 9896 010 2224.) for manually

measuring the Source Image distance

• Swivel range -45° to +45°, with lock position at 0°Manual control of rectangular shutters (DSC), by means of 2 continuously rotatable buttons

• Accessory Rails

• Aesthetic cover

• Plug & Play interface to X-ray tube assembly (see chapter 1.6.1 Compatibility page 9)

1.2 OPTIONS

Possible options for this BLD are:

• 9896 010 22071 transparent AEP-meter

• 4522 300 2417x NICOL DISC

• 4522 300 2418x NICOL P&P DISC

2 INSTALLATION

2.1 INTRODUCTION

This chapter contains general instructions about the installation of the BLD. For specific information at system level, refer to the relevant system reference manual.

2.1.1 TOOLS & TEST EQUIPMENT

• Standard Service Toolkit

• BLD alignment tool, code number 4522 980 31521, available from Service Logistics Best.

2.1.2 S

The BLD is delivered as part of a pre-installed system or in a single package, always containing:

2.2 I

Whenever replacing a BLD, no centering is required, provided the coupling flange is left on the X-Ray

UPPLIED ITEMS

• BLD (including aesthetic cover)

• Coupling flange assembly (to mount and adjust the BLD on the X-Ray tube housing)

• Four countersunk screws (M6x25mm) (used for mounting the shipping bracket to the coupling

flange, also are intended to mount the coupling flange to the X-Ray tube housing)

• Service Manual (No Operator Manual supplied)

NSTALLATION INSTRUCTIONS

• Remove the items from the packing and check them against paragraph 2.1.2 Supplied Items, for completeness.

• Install according sequence table below

NOTE

OUNTING THE COUPLING FLANGE ASSEMBLY NICOL

V2

This chapter describes the mounting procedure in case a pre-aligned X-ray Tube Assembly is used.

• Unscrew the locking plate screw (item 5, Figure 3, page 19) from each of the two locking plates (item 1, Figure 3) and push them outwards as far as possible.

• Remove the shipping bracket (item 2, Figure 3) together with the coupling flange (item 3, Figure

3) from the BLD

• Unscrew the shipping bracket from the coupling flange (countersunk screws M6 x 25 mm must be reused to mount the coupling flange on the tube housing.)

NOTE

Check the screw required length (25 mm) in the applicable tube housing service documentation.

At least 5 mm must be screwed into the tube housing.

________________

• Place the coupling flange (item 1, Figure 1) on the X-Ray tube housing (item 2, Figure 1) with factory mounted alignment ring (item 3, Figure 1)

• Positioning the reference pin (item 4, Figure 1) to the notch (item 5, Figure 1) of the alignment ring. Secure it with the four countersunk

•

screws M6 x 25 mm (item 6, Figure

1) and rings (item 7, Figure 1 )

• For screw length, see note above.

• Proceed with chapter 0 page 19.

CAUTION

Never loosen lacquered screws

(item 8, Figure 1. This will ruin the factory

alignment of the focus.

For realignment, the X-ray Source

assembly must be returned to Hamburg.

At least 5 mm must be screwed into the tube housing.

________________

• Place the coupling flange (item 1, Figure 2) on the X-Ray tube housing (item 2, Figure 2), positioning the 0° notch (item 5, Figure 2) to the rear of the X-Ray tube housing, and secure it with the four countersunk screws M6 x 25 mm, item 3, Figure 2. (see note above)

Figure 2: Mounting the coupling flange assembly

2.2.3 CENTERING THE BLD WITH RESPECT TO THE X-RAY TUBE

All BLD functions have been accurately centered in the factory, relative to the central axis; any further centering has to be done by adjusting the coupling flange assembly of the BLD with respect to the XRay focus. The specified alignment tool must be used. The centering procedure is described in paragraph 6.1.4, page 40. This procedure must be carried out:

• After replacement of NICOL DISC 4522 300 2417x

• After replacement of the X-Ray tube, configurations A and D of Table 3.

• NOT for replacements of NICOL and NICOL V2

Carefully mount the BLD to the coupling flange, in order not to DAMAGE the near focus shutters!

OUNTING THE

• Slide the two locking plates (item 1, Figure 3) outwards as far as possible.

• Mount the BLD on the coupling flange assembly, with the 0° locking mechanism (item 4, Figure

3) to slide into the notch (item 3) of the coupling flange

• Slide the two locking plates inwards to their end stop

• Secure the two locking plates to the coupling plate with the two screws (item 5)

• Check whether the BLD is properly secured

NOTE

________________

Figure 3: Mounting the BLD to the coupling flange

NOTE

It is strongly advised, to mount the BLD on the X-Ray tube housing without removing the aesthetic

covers first. This allows a better grip of the heavy BLD, and prevents damage to the ruler, when lifting

the BLD by holding the ruler by accident.
