FRAME (Carlos M.-C.)

  • Frame shipped on 6 January - expect at JLab in week of January 19th
  • not yet included: one spare PCB distribution board, soft-metal shielding box - working with Buckley Systems/NZ
  • Measuring radiation hardness of (10) Crytur crystals for comparison with SICCAS - should take photograph
  • standard: 30 Gy
  • could go to 1000 Gy and higher - try 1 MRad
  • 3000 Ci Co-60 source (1 MeV photons)
  • 1 week notice for facility


ASSEMBLY SPACE (Brad)

  • Floorspace: boxes from Orsay will go to Test Lab High Bay area, also for assembly, SRF group moving out
  • Setting up there, e.g. cables being moved there
  • NPS fully assembled designed to be moved into the hall


FAST ELECTRONICS GROUP (Brad)

  • LED driver boards - moving forward
  • Chris will update at the collaboration meeting: firmware on VTP, F250, LED driver board etc.
  • HV certification on connectors pending
  • Update on anode current tests at the collaboration meeting - Action: check with Fernando


MECHANICAL DESIGN (Paulo)

  • Cable layout/routing - ongoing
  • isolation NPS from ground
  • Detector rack/carriage waiting for delivery
  • Support for magnet


CRYSTALS - ESR REFLECTOR SHAPING (Vladimir, Carlos Y., Josh)

  • 10 tools were fabricated
  • HCList approved for work with oven
  • Test run with oven completed and 10 pre-shaped forms made
  • ESR(Al composite) ~ 60um, rigid - needs to be preshaped
  • Expect need 3-4 months to make ~1100-1200 pre-shapes
  • At collaboration meeting will have discussion about how to place tape etc. when wrapping crystals


DETECTOR SUPPORT GROUP (Aaron)

  • Fault chart development: crystal zone temperature/humidity - placement of additional sensors
  • Hardware Interlock system development
  • HV cable fabrication
  • Condensation - injection of dry air into frame - discussion still ongoing how to do it, e.g. details about the system
  • Action: Follow up with Jack Segal on dry air flow


SOFTWARE (Steve, Carlos Y.)

  • Working from SHMS calorimeter code - creating larger calorimeter
  • Plan to test with data samples from SHMS full waveform data (mode 10) from recent runs
  • Trigger NPS
  • trigger off HMS, clustering
  • in some kinematics where rates are high option for coincidence with NPS
  • full readout waveform - took some data with SHMS in recent runs


COLLABORATION MEETING AGENDA

  • Add talks:
  • Fast Electronics Group Update (Chris)
  • What needed for WACS for ERR (Bogdan or David?)
  • Under software: add discussion on critical path software, e.g., HCAna software modification


NEXT MEETING: NPS COLLABORATION MEETING 1-2 FEBRUARY 2021
