    This entry is a followup to: 233311

    keyword=Helicity and Charge Asymmetry

    I looked into the problem that Alexandre mentioned in Halog 233311. It seems that the problematic runs have a large charge asymmetry. This began last night with run 3444 and continued until run 3463. After this point, the charge asymmetry was exceptionally good for runs 3464 to 3519. Then the charge asymmetry was somewhat larger for runs 3520 and 3521. This is all based on the end-of-run file, which has been know to have problems.

    Dustin was running the HAPPEX DAQ last night until midnight and then started a run around the beginning of swing shift tonight. So there seems to be some correlation with the HAPPEX DAQ running. Dustin is looking into this.

    Tomorrow, I will check the charge asymmetries from these runs to verify that it was indeed high.
