Agenda

  • Eric and Aruni: prototype test plan.
  • TDIS Task list

1. nTDIS projections for 20 days (Arun, Carlos, Eric F, John, Rachel, Shujie)

2. Engineering run runplan (All subsystems) - total 15 days (2 days in 2015 proposal)

  • Establishing beam through 1 cm diameter 40 cm long straw target

with and without solenoid field ON.

  • Establishing optimal solenoid field.
  • Commissioning new Cerenkov and refurbished LAC as an electron detector
  • Establish and program electron roads for FPGA to get high efficiency electron trigger with the SBS.
  • Establishing high rate mTPC DAQ and deadtimes as a function of luminosity.
  • Calibration map of HV and gas flow settings for optimal operation of mTPC at different luminosity and target gas pressure.
  • Establishing and calibrating large angle single proton tracking in mTPC as a function of luminosity while monitoring rates and occupancy (with empty and H2 gas)
  • Establishing and calibrating two proton tracking in mTPC as a function of luminosity while monitoring rates and occupance (with empty and D2 gas)
  • Establishing background rates of two proton tracks in mTPC as a function of luminosity while monitoring rates and occupance (with empty and 4He gas)
  • Establishing background two hadron (proton/pion) tracks in mTPC as a function of luminosity while monitoring rates and occupance (with empty, D2 and 4He gas).


3. mTPC prototype tests (Aruni, Huong)

4. tracking algo tests and improvements (Aruni, Carlos, Steve)

5. Target thickness uniformity (Juan, Dave Meekins)

6. BoNUS12 rtpc eff. and tracking eff. (Aruni, Eric C)

7. SBS Cerenkov design (Burcu, Nadia)

8. LAC updates and electron trigger (Simona)

9. DAQ tests (Ed)

10. Plot from Patrick showing the ratio of new/old

Minutes

Present: Eric, Ed, Dipangkar, Aruni, Bogdan, Carlos

Excused: Rachel

  • Discussion about when to test the prototype at JLab, but it will depend at UVa availability since the staff have other tests scheduled.
