Vassu, Nathan, Zuhal, Bill, Brynna, James, Kent, Ciprian, Kate

Kate:

Sieve and blocker will now be 100mm thick unless our hole size study requires holes smaller than 5mm.
The sieve should be placed at a different z location than we've been using. Some basic calculations should be redone to check that we don't need to change important aspects of sieve design.

Nathan:

Initial look at GEM efficiency map looks good.
Next steps are to add in curves on the outer edges, make more realistically sized ribs, and define a more accurate function for the efficiency.

Vasu:

The vertical band on the E' plot looks to be coming from something between drift 2 and upstream of shielding.
v_z reconstruction using sieve_r can be used to define necessary radial separation for sieve holes.
