Minutes
Attendees: Igal, Sasha, Jane, Varun, Jared, Bill B., Igor S., Zisis, Tim B., Liping, Phil, Jon, S.T.
- Delivery schedule for second batch of SICCAS crystals remains uncertain
- Plan to wait one more week for update, maybe need to put hold on ordering more?
- In contact with CRYTUR, alternate source of crystals
- Company is interested, claim can deliver 600 by end of 2022
- Sasha plans to meet with CRYTUR representatives this week to describe JEF/FCAL insert project
- NPS (Hall C) previously procured 460 crystals from SICCAS but were not happy with quality -- maybe we can get these?
- Liping working on letter to management updating status of the JEF project
- Work on PMT divider continues: Fernando working on design for new prototype of PMT base
- Amplifier with separate power supply
- Time scale is 1-2 weeks
- COMCAL will use old base design but with bypassed amplifier, possible 3x amplifier for inner modules
- COMCAL refurbishment continues -- Josh making steady progress on LMS, lemo connectors installed, PMT dividers being rebuilt,...
- GW, URegina, UNCW groups can work on divider characterization -- Sasha will work on list of what can be done off-site
- A few more modules have been constructed, but construction rate is slow due to limited manpower
- Sasha will come up with construction plan with FTEs -- expect to get some help from Tim W.'s group
- Phil can provide some students to help out next summer
- Zisis' student will be available to start work on island algorithm studies in May
