Events



16:15  Compton people noticed only background counts regardless of the cavity status;

       MCC said Compton lock in chicane was off; asked MCC to switch it back on.

17:42  Initiating slug #38 with IWHP=IN

       Start run 6548 with reduced beam current of 45 muA (request by K. Paschke).

18:40  Go back to 58 muA

20:00  MCC perform PZT scan

20:20  PZT scan done, resume data taking

23:35  Asked MCC to position the beam closer to the required (1.6,0.0), (-1.4,0.0)
