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]
- 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

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
