−
* Discussed minutes from last meeting
+
 
−
* Looked at positioning of components in Z. Stephanie has updated the model to the latest.
+
−
* Pavel looked at radiation after experiment and it is decided we can remove the poly shielding 1 week after the end of beam in order to move the assy closer to the north wall
+
−
* Discussed Magnet design
+
−
** High rad resistant resin (CTD403) has hazardous characteristics with cyanide. It may be better (and cheaper) to use a resin such as CTD101K which is much cheaper but still radiation hard (10^5 grey).
+
−
** Give Pavel the current magnet model to run in Fluka to determine the needed radiation levels
+
−
** Magnet positioned 2cm below beam center
+
−
* Discussed the portion of the CPS that will be moved north after experiment
+
−
** May be a good idea to move the magnet with the absorber/shielding assembly
+
−
** Supporting magnet from the absorber assy support may be useful
+
−
** Steel shielding over magnet may be attached (not required) and moved with magnet to keep radiation levels down
+
−
* Radiator design
+
−
** may be a long shaft to bring motor outside shielding
+
−
** may be a rack and pinion or worm gear type of set up
+
−
** thick target, thin target and empty space needed
+
−
** target will be in air
+
−
* Vacuum window downstream of diagnostic girder may be 100um aluminum (2.5 cm diameter)
+
−
* Vacuum window on US end of permanent magnet may be Kapton if needed
+
−
* Pavel requests a nitrogen purge in copper absorber area
+
−
* Copper absorber
+
−
** Hovanes shows 52.9KW absorbed from Pavel model 78
+
−
** Tim's ANSYS model shows 51.14KW. Maybe ok sine the 8 1/2" water holes are in the model
+
−
** Eugene was concerned with brazed joints for water cooling
+
−
** After More discussion after the meeting, we will pursue brazing 3/8 inch tube into the absorber
+
−
*** Keith will work with JLAB vacuum brazing to come up with a prototype model to test
+
−
* Josh came up with a possible way to transfer models to Fluka from ANSYS. He will get a model to Pavel to see if this works
+
−
* The lead bricks are here from SLAC. A PR is written to get them painted
+
