Operators: akdogan egeis ----

During the first 7 hours of this shift period we didn't take any data. First, ABS
transitions are tuned (see log 21133), then the beam tune started. We started
taking data at 7pm (Run 5677), with 90mA maximum beam current (see log 21135.)

WC L14 keeps tripping. Reduced HV by 50 V.

With the new beam tune, we got almost no Compton backscatter photons, but
only the background. Performed laser and collimator scan to optimize this as
much as possible for this tune.
