    keyword=Compton Asymmetries After CIP Scan

    I performed a vertical CIP scan (Fig. 1) and slightly improved the signal. The new orbit lock is at a y-position of -0.95 (in BPM 1P02B).

    The bottom panel of Fig. 2 shows the measured Compton asymmetries for run 14945 (48-minute run). Asymmetries for left/right lase polarization look fairly symmetric.
