    keyword=Analysis Shift Summary - Mar20, 2300 to Mar21, 0300



    bb_tracking (2000 events each), online and qasy checked for the following runs.



    3216: okay. 7µA 5x5 raster (MCC)

    3217: 5µA beam with 3x3 raster (MCC). Low rates, high efficiencies. The run was progressing very slowly. In one hour it had a little less than 2M events! (To compare, regular runs complete 3M events in about 55-60 minutes.)

    3218: Back to 7µA 5x5 raster. Beam λ/2 plate changed. Qasy ∼ ±50 ppm. Rates and effs back to normal.
