Attendees: Igal,Sasha,Zisis,Jon,Liping,Varun,Tim B.,Susan,Jane
- Our MRI project was not funded; we discussed what to do next...
- Apply for a smaller grant?
- Go back to PAC to ask for more time given reduced insert size compared to our original plan?
- Need to revisit impact of smaller insert (80x80 cm^2 instead of 100x100 cm^2)
- Need to look at other hadronic backgrounds (in addition to 3π0 background).
- Crystal production: China is on holiday this week, assume production will resume next week
- Shipping of crystals SICCAS has already produced next week?
- Some material delivery issues, but want/expect to finish current contract within the next 2 months
- PMT base redesign developments: Sasha had installed a few new bases on the COMCAL -- disconnected cables, move to floor of Hall next week
- 2 bases did not work; still need to debug why
- Sasha plans to do LED tests on bench
- Need to coordinate between Vlad P. and Fernando B. to finalize design (resistor values,...)
- Zisis working on getting Regina involved in PMT base studies
- Module construction
- Nick S. working on temperature control for brazing; need to resume brazing tests
- Light guides: still need to order the full set, assuming the polishing has been improved
- Igal updated his presentation on the Dark Scalar boson search using η→π0γγ
- Slides 48-51.
- S/sqrt(B) is better for FCAL-2 than FCAL, but requiring 3 out 4 photons in insert appears to be counterproductive
- We encouraged Susan to contact her WASA colleagues to see if any are interested in joining the JEF effort
- Liping presented JEF at the recent Snowmass planning meeting; JEF was mentioned during several other presentations.
