Edinburgh group ion gauge turned OFF -> decrease in leakage current from 10.05 uA to 6.5 uA

GSI vacuum group ion gauge turned OFF -> decrease in leakage current from 6.5 uA to 3.63 uA

GSI large ion pump turned ON -> no effect on leakage current

Motors moved IN the same as elog 201. No significant increase in leakage current as moved further into the chamber (attachment 1). Pulser widths follow similar path as previous tests. Aida1 and 2 statrt with larger pulser widths which reduce as are moved into the chamber. Aida3,4 start lower than aida1,2 and remain at same level throughout. (attachment2)

RF ring signal removed from aida5. Data rate dropped back to ~20 kb/sec, Merger rate ~80,000 items/sec

Noise peak on aida1 appears reduced after gauges switched OFF with detector fully out (attachment 3) coompare to elog 201

Noise peak is removed once detector is moved in. (attachment 4)

Ey histogram (attachment 5) shows multiple peaks for the same pulser amplitude.
