Here’s some more strip plots of what was going on in BB GEM layer 4 top module (purple) compared with the bottom module (green) as they are set to the same voltage settings. This is what we observed when the GEM was powered on this past Sunday for an hour (~3-4pm). 

Some key points: the original no-beam current draw for this detector was -734 uA. I am not sure what is happening in this GEM from 1530-1540h. It is still doing something with beam which is kind of consistent with us seeing some hits in it, but it is clearly drawing a higher current (although the changes are similar between the two GEMs…about 12uA from no beam to beam on).
