keyword=poor sig/bgr, stop Compton tune
Alex tried varying the beam current to find a good signal-to-bgr
for Compton. Last week when the current was low this ratio improved
dramatically (it was not understood why). But tonight it actually
got worse with low current. Alex also tried the dogleg adjustment.
No improvement. We are stopping now. Back to 85 uA production.
There is basically no signal in Compton, sig:bgr = 1:20 approx.
