    Shift summary:
    ===================

    00:00 MCC still complaining about unraster beam in LH2 or LD2 target (database is still not updated). I paged RC to call them once again tonight.
    00:23 2607 run finished (gain 3000 current 5uA).
    03:10 Asked MMC for controlled access to change detector configuration (going from elastic to DVCS configuration)
    We needed a second access to move the left spectrometer to the right angle (19.32 degrees). Momentum was set to 2.95 GeV.
    04:40 Back on beam permit. Target changed to LH2. Starting DVCS runs.
    From now on (run 2614) we are running with a lower calorimeter trigger.
    05:15 Run 2614 contains no proton array or veto information. Alex is coming.
    06:04 Problem fixed (see Alex's entry). Run 2618 is a good one.
    07:45 We increased the current to 5uA to check ADC levels in detectors. I turned off veto as the ADC currents were too high. PA seems ok.
    08:10 Changed target to LD2 and start running at 2.5uA.


    ================================
    Summary of runs :

    Elastic config:
    ----------------
    Run 2607 : GainPA 3000 Current 5.0uA 4kevents
    Run 2608 : GainPA 3000 Current 1.0uA 10kevents
    Run 2609 : GainPA 6000 Current 5.0uA 12kevents
    Run 2610 : GainPA 6000 Current 2.5uA 10kevents
    Run 2611 : GainPA 6000 Current 1.0uA 10kevents
    Run 2612 : GainPA 3000 Current 1.0uA 10kevents
    Run 2613 : GainPA 3000 Current 2.5uA 11kevents

    DVCS config:
    -------------
    Run 2614 : LH2 2.5uA DVCS config. 24 kevents. No signal in PA+Veto. CaloThres 80, higher HV.
    Run 2615 : LH2 2.5uA DVCS config. 22 kevents. No signal in PA+Veto. CaloThres 80, higher HV
    Run 2618 : Same config as before. Problem fixed.
    Run 2619 : LH2 2.5uA DVCS config. 29 kevents.
    Run 2620 : LH2 2.5uA DVCS config. 32 kevents.
    Run 2621 : LH2 2.5uA DVCS config. 27 kevents.
    Run 2622 : LH2 5.0uA DVCS config. 27 kevents.
