The plan was to take two runs with and without gas, field on to see
if, after last few days hardware debugging, everything is back on track
again.

However, we did not have beam until 9:00pm, compton polarimeter study
continued till after 11:00pm, and there was not time to optimize the beam
for target.

Turned on detector HV after one fill at 11:25pm, single, rates are
extradinarily high. With empty target, field off, 50mA
        phys0: 6000, phys1:130000, phys2:660000, phys3:800000
        LTT0: 120000, 100000, 100000
