Meeting time and location:

Agenda

Preparation of parts for FCAL2 modules -- Sasha
- Crystals:
  Received 30 crystals from CRYTUR [1]. Remaining 65 crystals will be sent to us during this and next month.
  
  Wrapped crystals ready for fabrication (Mindy): 26 SICCAS and 5 CRYTUR
  
  Can be wrapped: 10 SICCAS + 28 CRYTUR
- George (DSG group) preshaped 96 ESR reflectors; finished with preshaping.
- More than 200 long signal cables received, can start checking, bundling, labeling
- Procurement parts for the LMS
  Ordered 16,000 ft of optical fibers. Expect that they will be delivered in May. Adding additional 8000 ft to the PO
  
  Ordered 18000 of polycarbonate donats
Module fabrication -- Sasha
- Fabricated modules: Total 1487
  Available for fabrication: 26
  
  Fabricate 36 modules using 'low quality' crystals for stacking mockup and 'crash' tests (train students on them)
Testing of PMT dividers -- Sasha / Vlad / Arshak
- FCAL2 modules with dividers installed on the CCAL [2]
- Met with Vlad P. on Tuesday. Fine tuned the divider circuit (modified some resistors). Chris S. ordered new parts
Installation of the FCAL2 detector & integration to GlueX -- Sasha / Arshak
- Detector installation page
- Updates from the meetings with Tim's group [3]

Discussion of the FCAL2 installation procedures [4]

- Manpower and division of tasks
- Projects for summer students
- Summer Students (2023)
Light Monitoring System -- Arshak

 *'''Preparation of parts for FCAL2 modules''' -- Sasha
 ** Crystals:
-**: Received 30 crystals from CRYTUR (out of 95 [https://halldweb.jlab.org/wiki/index.php/CRYTUR ] )
+**: Received 30 crystals from CRYTUR [https://halldweb.jlab.org/wiki/index.php/CRYTUR ]. Remaining 65 crystals will be sent to us during this and next month.
-**: All crystals from the CCAL prototype were removed
+**: Wrapped crystals ready for fabrication (Mindy): 26 SICCAS and 5 CRYTUR
-**: 26 crystals were wrapped by Mindy
+**: Can be wrapped: 10 SICCAS + 28 CRYTUR
-**: Number of available crystals: 1487 (modules) + 26 = 1513,  expect to receive 95 from CRYTUR: 1513 + 95 = 1608 (12 spares)
+** George (DSG group) preshaped 96 ESR reflectors; finished with preshaping.
-** George (DSG group) unwrapped CCAL modules and removed LMS caps. Preshaped 48 ESR reflectors, have to preshape 32 more.
 ** More than 200 long signal cables received, can start checking, bundling, labeling
 ** Procurement parts for the LMS
