Attendees: Bill, Arshak, Varun, Igal, Azizah, Susan, Sasha, Liping, Jon, Jane, Phil
- No significant update regarding new batch of SICCAS crystals
- Joanna still working on wrapping crystals
- COMCAL refurbishment continues
- Sasha found a couple of problematic channels, now fixed
- Still working on light uniformity from fiber bundles
- Move to hall next week?
- Azizah working on comparisons between FCAL/FCAL-II and Isand/Default algorithms
- Looking at two 1 GeV clusters separated by a small angle
- Interesting features show up for clusters near the transition between the insert and the regular FCAL blocks
