Attendance
Ciprian, Bill, Zuhal, Nathan, Vassu, James, KK, Kate
Minutes
Kate:
- calculations for sieve geometry were redone to account for changes in sieve thickness and location.
- sieve inner bore radius can stay the same.
- optimal sieve hole location is slightly different.
- radial range of "allowed" sieve holes expanded some.
Nathan:
- GEM efficiency map now has outer curves and smaller ribs (neither are fully realistic but are a better approximation)
- showed that we can cleanly plot multiplication of electrons through GEM layers.
Vassu:
- sieve hole locations
- need to be slightly updated.
- sieve hole separation
- using beam generator, it is difficult to distinguish holes as well as background from moller events
- different magnetic fields could be used for different passes to separated eP and moller events
- strange bimodal distribution needs to be investigated
