Shift Summary:
------------------------------------------------------------
1. Beam since 10:30, lost at 13:30 due to quench link interlock. Initial ZDC rate was 1700 at the end of run 900.

2. DC scan runs: 7627 to 7633,
   run #7627 - HV_nom - 100V
   run #7628 - HV_nom - 50V
   run #7629 - HV_nom - 20V
   run #7630 - HV_nom 
   run #7631 - HV_nom +10(T3) + 20(T4/T5)
   run #7632 - HV_nom +20(T3) + 40(T4/T5)
   run #7633 - HV_nom +30(T3) + 60(T4/T5)

Run 7634 is a normal production run. For all the data runs (7627 to 7633) D5 was off.

Runs 7626, 7635 and 7636 are DVM calib., pedestal and TPC pedestal, respectively.

After a preliminary analysis of DC scanning runs decided
to keep HV=HV_nom+10(T3) +20(T4/T5).  

Mapping change (affter run 7634) to removed the hot wire #48 in T3-1-V1.

FV played with triggers see. elog for details.
