Action Items

  1. BCAL pedestals: Tegan (UofR) will summarize the determination of pedestals in a note with plots in preparation for the collaboration meeting.
  2. Wish-list of action items: discuss attached document (Media:BCAL_Action_Items-2015.pdf) and add chosen items to Wiki page. Zisis will update the list
  3. Will: Create histograms to determine number of pi0s and pi0 width for online monitoring.
  4. Work with Hovanes to activate VME LED pulser setup for FCAL (Elton)

Minutes

Attendees: Elton, Adesh, Will (L207); Manuel (Hall D); Sean (NW); Zisis, Tegan, Noemi, Ahmed (UofR)

  1. Announcements
    • Accelerator close to delivering 3-beam operation
    • Beam loss monitors are currently preventing beam delivery to Hall A at five passes.
    • Solenoid is at 1200 A
    • Hoping for beam this evening.
  2. Action Items
  3. Run conditions
    1. BCAL temperature, overbias settings (Elton)
      • T=10degC for chiller (~11-12 degC on SiPMs), voltage setting for 12 degC, overbias setting is 1.4 V
    2. Data with mode8. Most data will be taken in mode7.
      • Expect to take about 1 hour of mode 8 data per shift
      • Need to check that mode 7 data quality is similar to mode 8 running.
    3. HV updates for FCAL (Manuel)
    4. Efficiency in BCal Bias Scan (Foda)[5]
  4. Reconstruction and Simulation
    1. Changes to reconstruction with single-ended hits (Mark)
  5. Calibration
    1. Feb LED runs (Noemi)[6]
    2. pi0 calibration (Will)
    3. Amount of data needed for calibration (Elton)
    4. pi0 and electron calibration (Adesh)[7]
    5. Pedestals (Tegan)
  6. Any other business
