MAGNET (Bogdan)
- TOSP ready, temperature sensors installed
- First magnet test (post meeting update):
- The magnet test was performed with current up to 200 A (20% of nominal). The field was found within 2% of expected.
- Next step will be with 250 A and full spec: 5 Gauss boundary.
- After that ODU will schedule to do mapping.
PMT AND HV DIVIDER
- Follow-up on previous meeting action items ongoing, updates at next meeting
- V. Popov produced new optimized base - will be tested in Hall D
- Number of PMTs and inspection:
- Currently have 542 PMTs in the cleanroom: 392 + 150(8/20/2019)
- The diameter has been measured for more than 200 PMTs - none have been close to critical dimension, all have ~200um of clearance
- Action item: Make list of PMTs
FRAME AND SIMULATIONS (Carlos)
- Background sources track-down ongoing, anticipate to show results at next meeting
- Frame construction is proceeding well and on schedule
- receiving parts
- final box design complete - in discussion with Paulo to make sure that everything fits in the hall, e.g. with beam pipe and magnets
- Discussion about availability of people for NPS assembly
- Timeline: starting in or after September - decide on final schedule in January 2020
- Tasks: anticipate 2-3 months work for 2-3 people - IPNO engineers will provide training at start of assembly
CRYSTAL STATUS (Vladimir, Tanja)
- Current count: ~350 Crytur crystals received and inspected (no rejections, one crystal sent back for repolishing)
- Next orders: expect +300 (+64) Crytur crystals (~500 SICCAS for FCAL)
- Check on additional Crytur order (~200) in next calendar year to offset ~145 currently in Hall D
- Action items:
- Make list of Crytur and SICCAS crystal orders (when ordered, when received, when inspected)
- Make list of crystal properties
CRYSTAL PAPER (Vladimir, Tanja, Carlos, ...)
- Please send comments - idea is to submit for publication before end of the year
INFRASTRUCTURE - NPS ANGLES AND DISTANCES (Julie, Paulo)
- For elastic kinematics for calorimeter calibrations need smallest possible angle - 6 degrees at 4m
- Action item: document minimum angles and distances for the general NPS facility
NPS COLLABORATION MEETING 2020 - MONDAY 3 FEBRUARY, 2020
- Plan for week of February 2, 2020, adjacent to Hall A Winter Meeting
NEXT MEETING: THURSDAY 31 OCTOBER AT 9:00AM (ET)
