    keyword=Left BPM observations

    The last run with good data on the Left BPM ADCs was 2088 (Done 8:04am, Wed Nov. 11). Right after that the Hall went to controlled access.

    The very next Left arm run (2089) has very different BPM data then the corresponding Right arm run (20601). Those runs started at 10:52am (cosmics).

    The only left arm work mentioned in the day shift summary is "work on calorimeter (A. Camsonne)". John Musson made an ELOG entry at 12:36pm about BPM work he did during the same time frame.
