    20:17 permission granted to put Edet into electron position.

    Previously, with 5-pass and 60 uA the Edet was drawing too much
    current (off-scale) so we'll slowly increase current and see
    what we can tolerate.

    Edet at 7 mm. Beam current 6 uA. Rates seem tolerable,
    Edet is drawing ~1.6 uA which is pretty high.

    Michel has prepared a firmware to trigger on photon and make
    an "unbiased snapshot" of the Edet, as far as I understand it.
    We speculate that the inefficiency is due to background and
    noise fooling the trigger -- maybe. Will use it shortly.

    Starting with a normal firmware.

    Run number 17545 .... Test2 config.
