    keyword=Compton reboots and tune

    Around 1400 we had Compton background rates of around 400-500Hz/uA. MCC had trouble improving upon this, in part due to not being able to take a harp scan. This was corrected after a reboot (by MCC, requested by Hall A) of iocha1.

    The Compton ROC's crashed around 1600, and had great difficulty booting back up. By 1700 they were back up, and MCC (under direction of Mike Spata) adjusted the optics of the beam line (see elog
    1313080) to reduce the background rates to less than 40Hz photons and 150Hz of electrons. Very nice.
