I just noticed that the front most UV chamber goes up to currents of about 837 uA when running on LH2 at 15 uA beam current. I had set the trip limits of the UV GEMs to be at 840 uA but I felt that there is a good chance for chambers to trip if we keep the trip limit there; especially when we run at 8 uA on LD2.

So I increased the trip limit of the UV GEMs by 5 uA to 845 uA.
