Meeting time and location:
- 9:30 am EST (JLab time) remote only
- Connection information
Agenda
- Preparation of parts for ECAL -- Sasha
- - signal cables and 2 patch panels [1] - done
- - HV short cables: done
- - HV long cable, 18 ready (out of 36)
- - HV distribution boards: not designed
- - LV cables: missing about 20 cables, waiting for the last delivery batch.
- - LV distribution boards [2]. One board out of 4 is ready
- - LED: the prototype of the LED board has been received. Chris will populate it with components
- Ongoing projects
- - Update from Laveen
- - Testing, labeling and bundling LV cables
- Testing of PMT dividers -- Sasha / Vlad / George / Mindy
- Installation of the FCAL2 detector & integration to GlueX -- Sasha / Vlad / Hakob / Laveen
- Summer students -- Sasha
- - 2 students from UNCW (May 15), 1 student from GWU (May 19) All paper work has been completed, they are ready to come.
- - Projects: document all test results, assist with the cable/divider installation, install signal cables on patch panel, work on the ECAL monitoring plots
- 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 (?)
- FCAL2 poster for open house?
- JEF/ECAL/FCAL poster (Laveen + students + feedback from all of us)
- Analysis/Simulation
