Agenda
- PREX1 dump: Ciprian slides
- CG: with the updated PREX1 numbers our total radiation dose for PREX2 + CREX is (31+14)% (compared to the old 38+17 before). For the fat pipe we now have (24 + 11)% vs (19 + 13)% before
- skyshine sheilding: Adam slides
- AZ: still having issues with reproducing err hall lid numbers with the current current simulation setup
- KK: find out if what percentage iron is in these green blocks
- acceptance envelope: Kent haplog3470
- KP: this is important because of the tight constriaints for the collimator box to q1 vacuum enclosures. it currently just barely fits but we need to take into account alignment tolerances.
- KP conservative I estimate 3 mm alignment tolerances + 3 mm acceptance buffer
- KP: att 1: red line is where the wall would be, and green is the 6 mm tolerance . the green is the same as tyler’s cut corresponding to 4.5 deg from target
- KP: att2, 3 the influence of these cuts on rate and FOM. the rate seems to be different from att 1 (will investigate further)
- KP: leaning towards a bend in the vacuum enclosure.
- KK: we should make some more plots to look at the neutron skin sensitivity in 1D
- HRS magnet tuning: Ryan haplog3467
- RR: look at the AT enhancement in the focal plane using PREX1 data.
- RR: HRS trans allows for calculation for the transport through the HRS at 1st and 2nd order
- GU: how large is the shift US from the raster? RR: about half of meter
- SR: we would like to have a tune that minimizes the shift. Even the current tune would not disastrous in x but for y we could do better.
