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
