Meeting time and location:

• 9:30 am EST (JLab time) remote only
• Connection information

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

• • Installation and testing cables and dividers [7]
  • Installation of long signal cables [8]
  • Installation LV patch panels and cables [9]
  • Installation of optical fibers [10]
  • Detector installation page
  • Safety briefings
• 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
  • Update from Laveen

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
