Simulation Task List Updated 2019
- Simulation tasks (new)
File:MOLLER Tasks List v8 Sim.doc
Agenda
- Immediate simulation tasks to complete - Ciprian, Sakbi, Chandan
Attendance
Attendance: Ruben, Ghosal, Sandesh, Rakitha, KK, Ciprian, Dustin, Chandan, Wouter, Paschke, Sakib, Micheal
Minutes
- Background radiation summary by Ciprian.
- Ciprian: Sakib ran 100 million events for background radiation.
- Ciprian: At -1800 mm we have US window that separates us and ds region in the beamline. It is 0.5 mm thick Al.
- Ring 7 1200 - 1500 mm is the PMT region.
- Dustin: Light guide size and ring radial reach, no agreement so far on final sizes.
- Units in 1D plots hits per unit target election
- KK: Photon background is too high at the R5 mainly dominated by E>10 MeV gamma high e neutrons at PMT region (R7)
- We need to estimate numbers for R7 region and see how much shielding we need and how much damage neutron will do for PMT
- Low energy neutrons have high capture cross-section at the PMT
- What thermal neutron will do for PMT
- Do we have thermal neutrons in the simulation? Sakib ran with HP physics list.
- KK: How much high E neutrons coming from shower-max?
- Michael: Moving all the pre-amp behind the lead ring shielding. There is a limit on how long cables we can use. This needs to be tested to check the max length of cables we can use from PMT to pre-amps
- Ciprian: Sakib ran 100 million events for background radiation.
- To-do list:
- new beampipe design, reduce lead absorber to actual size and implement a new beam dump physics process to include thermal neutrons.
- Separate simulation for SAM
- What's the timeline?
- KK: if we can get numbers by April 2 then go for optimizations. The first step will be to get the numbers (dose, rate, etc) at the detector plane based on current simulation.
