11:00 → 11:20 material budget requirements and target goals

attached pdf on the discussion about material budget from Zhenyu and Matt

1. What is the required tracking angular resolution from the DIRC for
   tracks less than 6 GeV?
2. What is the max momentum the BToF can reliably reach? If upper
   momentum reach of the BToF can provide good PID for the lower
   momentum reach of the DIRC, then maybe the DIRC performance
   could be relaxed in that region, if tracking is having a difficult time to
   meet its requirement.

11:20 → 11:40 BTOF ASIC choices?

There are quite some discussions about what we should put in as default choice for BTOF ASIC.
See Satoshi's summary at ePIC collaboration meeting.
We should continue this discussion, and hopefully arrive at
a reasonable choice based on requirements, performance and availability.
