    keyword=Compton Coincidence Runs

    100uA beam. Moved EDet to 1.0mm.

    **Run 20211: Tried electron only, with FADC trig on edet. Prescales set to 4%, 100%, 100%, 2 plane coincidences. No events.

    Reboot ETROC. Re-download firmware. coda reboot

    **Run 20213: This time there's data.

    **Run 20214: Electron only run.

    Moved EDet to 0.0mm

    **Run 20215: Electrons only at 0.0mm. We'll stay here.

    Go to 15uA beam.

    **Run 20216: e-g coincidences, prescales set to 4%, 0%, 100%. Looks okay!

    Back up to 100uA.

    **Run 20217: e-g coincidences at 100uA. Doesn't look good.

    EDet moved back to garage.
