Meeting time and location:

Agenda

  • Preparation of parts for ECAL -- Sasha
    • - HV long cable: Sammy and Mindy have to assemble 10 cables
    • - HV distribution boards [1][2]
    • - Fix front panel of two LV distribution boards, re-install the boards on the detector frame [3]
    • - LED: Started testing the prototype of the LMS (need to make the detector room light tight)
  • Installation of the FCAL2 detector & integration to GlueX -- Sasha / Vlad / Hakob / Laveen
    • Report from students [4]
    • Installation of HV cables [5][6]
- two remaining bundle of cables will be ready in about a week
  • Students -- Sasha
    • - Expect one student from Wuhan, paperwork is in process.
  • Beam tests with the PS
      • measure shower beam profile and reconstruction in the crystal/LG transition region
      • (install prototype with 5x5 PbWO4 modules + ? LG)
  • Other hardware projects
    • prototype of the ECAL veto counter (?)
  • Analysis/Simulation

Minutes

Attendees: Bill, Igal, Sasha, Laveen, Vlad, Hakob, Ilya, Phil, S.T.

  • Bill will be representing JEF at a workshop in Krakow, Poland in September (19th-20th): [11]. We should provide him slides this month.
  • Installation of PMT dividers in the top half of ECAL continues
    • Looking at signals on oscilloscope
    • Rate 1 layer/day
    • Found some loose connections and loose soldering joints (connnecting PMT sockets to printed circuit boards)
  • Assembly of HV cables continues (now have 30 out of 36)
    • Will have two bundles of 18 connected to HV distribution boards
  • Laveen gave an update on 2-shower separation studies using Island Algorithm for HyCAL geometry
    • Separation efficiency depends on relative energy between 2 showers
