Hall D Geometry Data Base: Beam Line
************************************
version 1.0: Initial version -rtj
Revision 1.1 10/18/2002
-added concrete shielding to the collimator housing
-added the virtual detectors to this code:
DET1: disk intercepting entire beam upstream of collimators
DET2: plane perpendicular to beam just after second collimator
DET3: plane mounted just below the ceiling of collimator cave
DET4: plane perpendicular to beam just after entry to hall
DET5: plane perpendicular to beam at photon dump end of hall
DET6: plane mounted just below the ceiling inside the hall
DET7: plane perpendicular to beam just before the target
-added a steel tube containing a vacuum that goes from the back of
the collimator to the front of the solenoid
-csg-
Revision 1.2 10/28/2002
-revised collimator to the heavy shielding option
-added a steel tube containing a vacuum in the WALL, SHLD and ABS2 volumes
-repositioned DET3 to be inside the collimator housing
-removed the BEAM volume from the collimator system
-csg-
Revision 1.3 1/9/2003
-shrunk the size of the vacuum tube from r=5.3 to r=2.5 in order to
extend the tube into the second steering magnet
-csg-
Revision 1.4 06/16/2003
-mid-shielding option
-modified DET1, now a cylinder placed in front of primary collimator
-added tungsten pin-cushion detector model into simulation
-csg-
Revision 2.0 05/16/2008
-moved DET2 to just after the second collimator, in agreement with
the comments below. Somehow it got misplaced to upstream of the
second collimator. I guess no one was using it until now.
-added the volume CONV for the pair conversion target located inside
the vacuum pipe just downstream of the second sweep magnet. Right
now it its material is vacuum, but the thickness of 240 microns is
chosen to make a 0.1% converter if the material is set to Carbon.
Revision 2.1 12/12/2008
Made the following changes in the composition 'collimatorStack':
1. Added the composition BeamPipe0 describing a vacuum beam pipe at the entrance
of the collimator cave:
- the beam pipe radius is 12.4 cm
- the exit window: 250 micron Kapton with the radius of 10.14 cm.
2. Moved the active collimator, DET1, and other components 83.96 cm upstream the
beamline.
3. Changed layout of the 1st passive collimator to a composite W/Pb:
- the inner part is a W box, 5.08 x 5.08 x 20.0 cm3
- the outer part is a Pb box, 30.48 x 30.48 x 20.0 cm3
4. Added the vacuum beam pipe (Flange1 compositon) in front of the 1st sweeping
magnet:
- use 150 micron Kapton entrance window
- vaccuum goes all the way downstream the beamline until the GlueX detector.
5. Modified the layout of the 1st sweeping magnet:
- the outer dimensions are 29.2 x 24.8 x 355.6 cm3
- the gap size is 10.22 x 4.9 cm2
- the field inside the gap is 0.23 T (integrated field is 0.82 Tm)
- the elliptical vacuum pipe goes through the magnet. The semi-axes of the pipe
are 4.95 cm and 2.29 cm.
6. Added the concrete blocks around the 1st sweeping magnet, composition ConcreteWall1.
The size of the wall is 101.6 x 147.32 x 121.92 cm3.
7. Added the composition Flange2 to connect the 1st sweeping magnet with a vacuum chamber.
8. Added a vacuum chamber after the 1st sweeping magnet with the following dimensions:
- 50.8 cm long tube with the inner and outer radii of Rin = 9.83 cm and Rout = 9.85.
9. Added the small lead wall after the vacuum chamber, composition LeadBand1.
10. Added the composition Flange3 to connect the vacuum pipe between the lead band and the
2nd collimatoor.
11. Changed material of the 2nd collimator from Nickel to Iron. The default pinhole
diameter was changed from 1 cm to 0.6 cm.
12. Added the composition Flange4 to connect the vacuum pipe between the 2nd collimator and
the 2nd sweeping magnet.
13. Changed the layout of the second sweeping magnet:
- outer dimensions are 42 x 20.8 cm2
- the gap size is 20.3 x 5 cm2, the field in the gap is 0.23 T
- 1.75 cm radius vacuum beam pipe goes through the magnet.
14. Added the composition Flange5 to connect 2nd the sweeping magnet with the vacuum beam
pipe.
15. Added a 1m long vacuum beam pipe. The inner and outer radii are 2.38 and 2.54 cm,
respectively.
16. Added the small lead wall (composition LeadBand2), 81.28 x 20.32 x 10.16 cm3.
17. Placed the vertical plane DET2 after the lead wall.
18. Added the composition Flange6 to connect the vacuum pipe between the lead wall and
a pair spectrometer converter box.
19. Added the pair spectrometer converter. The converter thickness and material can be set
in the box 'PTAR' <box name="PTAR" X_Y_Z="1.0 1.0 0.0445" material="Aluminum" />.
20. Added the composition Flange7 to connect the vacuum pipe between the converter and
the concrete wall.
21. Modified the size of the concrete shielding wall to 450.0 x 270.0 x 121.92 cm3.
Added passage to the collimator cave.
22. Decreased thickness of the lead wall to 5.08 cm (size of the lead brick).
Revision 2.2 12/22/2008
Modified the composition 'beamPipe'. Now 'beamPipe' extends the vacuum from the
pair spectrometer to the position of the target.
