Agenda

1. Update on sieve and blocker z placement and geometry [Kate] [1]

2. Update on GEM Efficiency Map and optimum orientation [Nathan] [2] [3]

3. Sieve Hole Placements [Vassu][4]

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
