581 update upstream 2bounce shield #582

Closed rahmans1 closed 1 year ago

rahmans1 commented 1 year ago

Update 2 bounce shield modified to closely match MIT CAD specs.

Inner r is 25 mm, outer r is 36 mm. Slots are cut out from 32 mm to 36 mm in radius to fit coils. Length is 2152.65 mm. The upstream face is at 936.5 mm, not right against C2.

Additional context [Studies showed no adverse effect from modified 2bounce design on spectrometer dose.] (https://moller.jlab.org/DocDB/0010/001029/001/UpstreamDose_status.pdf)

Would be good to check the effect on detector background before merge. High priority item.
