Items for followup from previous meeting

Collect this information of testing (including goals and setup) on the wiki for ease of presenting information. (USM)
~~The JLab team should seriously consider a NIM article for the extensive work on SiPM radiation hardness.~~ Yi will prepare a draft

Attending: Joh, Elton, Fernando (JLab); Will (USM)

Announcements
- Will is attending a RICH Workshop in Frascatti covering many new technologies, which might be of interest for GlueX. The RICH detector/strangeness physics workshop link is [1]. To see the talks, you go to "program" and then to "timetable".
Review of Action Items
Update - USM
- no update
SiPM Radiation Hardness Test (Update from Yi)
- No update
Electronics/cooling
- Decision on precise configuration of SiPM summing needs to be made
- Specification of light guides -- see below. Note that number of photoelectrons assumes 50% loss in light guides, so the trapezoidal guides are consistent with our plans.
- Cooling and mechanical assembly details need to be completed
Geometry and light guides:GlueX-doc-1432:
- Note that the red circles (gap between guide and light sensor) show a 60% transmission at small gaps. This is what was measured by Athens.
Monitoring system
Simulation runs
