Meeting time and location:

Agenda

  • Preparation of parts for ECAL -- Sasha
    • - signal cables - done
    • - signal patch panel [1] - done
    • - HV short cables: received, checked, labeled (last week)
    • - HV long cable, 18 ready (out of 36)
    • - HV distribution boards: in preparation
    • - LV cables: 100 cables received, 500 cables in total
    • - LV distribution boards [2]. Have to populate with connectors, and design a box around the PCB
  • Ongoing projects -- Sasha / Vlad / Hakob / Laveen
    • - Tested and labeled all HV cables ! and about 100 LV cables
    • - Bundling short cables (groups of 7, 7, and 6 cables)
      • finished: LV - 7 layers, HV - 17 layers, signal - 4 layers
  • Testing of PMT dividers -- Sasha / Vlad / George
    • - Testing procedure [3]
    • - About 1400 dividers have been fabricated (Chris, Armen, Mindy)
    • - Started removing power regulators on the newly fabricated dividers
    • - George has tested 54 dividers (919 have been tested in total) [4].
    • - Adding ECAL (and updating FCAL) translation table in the TT.DB (needed for EPICS scalers)
  • Installation of the FCAL2 detector & integration to GlueX -- Sasha / Vlad / Hakob / Laveen
  • Analysis/Simulation
