Today we took GEM data during teh fast feedback beam study tests. We started the GEMs at 3500V. 

Run 1354, all HV at 3500V, beam current at 2.5uA on D+rad
Run 1355, HV at 3500V, target is hydrogen, beam current ranged from 5-25uA
Run 1356, HV at 3550V, target is hydrogen, beam current range from 2-20uA
Run 1357, HV at 3575V, target is deuterium, beam current 13-18uA
Run 1358, HV at 3600V, target is deuterium, beam current 18uA
Run 1359, HV at 3625V, target is deuterium, beam current is 18uA
Run 1360, HV at 3625V, target is deuterium, beam current is 18uA (Run taken in full readout mode....2% livetime)
Run 1361, HV at 3625V +5V on all G1, target is deuterium, beam current is 18uA, BBL0 had some intermittent issues on transfer region
