Agenda
- Dump Shielding Summary: Ciprian slides
- half-target
- KP: the number of coulombs for the half target should be doubled, but it looks like there should be some advantage to doing this
- KP: run full target 4 in donut CG: will do
- KK: object to change the target, because it’s not trivial for the machine to give us 150uA. we need to have the prex 1 configuration
- KP: half donut without the donut change and 3/4 target
- H2O shield
- DG: having a large volume watertight and assembling it in place.
- SR: we should consider ionization and eating up of walls; creation of free radicals (chemical problems)
- DG: i will ask Keith Welch
- fat pipe with prex2 end:
- CG: this resolves both PREX2 and CREX dump radiation problems
- FLUKA simulations: Victoria
- VO: updated geometry
- VO: running simulations to benchmark the power deposition to G4
- KP: ultimately we want to look at the radiation coming off activated materials that we can input into other simulations
- Progress at JLab haplog3444
- KP: colimator build according to the design document
- KP: the jacket is not pure tungsten but some alloy (KD17)
- KP: the hall has already ordered hard line water connectors for the Q1s
