Meeting time and location:
- 9:30 am EST (JLab time) remote only
- Connection information
Agenda
- Preparation of parts for ECAL -- Sasha
- - signal cables: Received all needed long cables. Redid and tested 4 bundles. All cables are ready.
- - signal patch panels are ready [1]
- - HV cables: have received 330 short cables, have been testes and labeled. 800 cables are ready for installation. Long cables are in production
- - HV distribution boards: Chris is finalizing design of the distribution board, should order 4 boards soon.
- - LV cables: ordered, lead time unclear
- - LV distribution boards. The design of the LV distribution board has been finalized. Boards will be ordered during next week.
- - Optical fibers: received all
- Ongoing projects -- Sasha, all
- - Testing and labeling cables (Recently labeled cables in boxes)[2]
- - Prepare modules for the TAC and prototypes (using crystals with some imperfections) [3]
- Wrapped crystals - done
- Parts for TAC[4] - done
- Modules for prototype (25 are ready) - done
- - Preparation of the LMS
- - Summer Students (2023)
- Testing of PMT dividers -- Sasha / Vlad / Aoran / Boaxin
- Installation of the FCAL2 detector & integration to GlueX -- Sasha / Vlad / Hakob
