HAPPEX run summary from 1/28 Swing Shift



16:14 Oversampling set back to zero. Starting a new run 10414

17:13 Moving to C target. Starting HRS DAQ (run 3563)

18:20 MCC having problem with IOC. Beam off.

18:50 ATLis test finished. Asking for Controlled Access to work on Compton and Lumi

20:05 MCC fixed IOC problem. Beam will be back soon. Hall is still under controlled access.

20:55 MCC has vacuum problem. An expert has been called in. About an hour to the beam.

22:00 MCC has fixed the vacuum problem. Alex and Vince have fixed the scaler problem and leaving the hall. Basically ready for the beam.

22:23 Beam back starting HAPPEX run 10418. 10uA on Carbon target.

23:59 At the end of the shift, Luis and Dustin is doing some LUMI tests.



If not noted otherwise run has been analyzed and regression has been done
