keyword=Compton electron detector run list
It seems the situation is worse at 5 pass than at 4 passes, detector draw
about 1 uA in plan A at position 23000 compared to 26000 at 4 passes.
Might try a low current run later but the detector cannot be put in beam
for now. For reference lower limit switch is at ~34000 and 400 turns is
rougly 1.5 mm so detector reaches 1 uA at about 3 cm from the beam.
Though I don't have a good idea of how much the detectors are supposed to
draw in beam. Will have an idea before putting it in beam.
