****************
08:10 Giving back the beam to MCC in order to improve the cathode to be able to
go to higher currents (130uA is our target value).
10:15 Beam is back, asking 5uA to check the beam parameters.
10:25 Raster problems, MCC loose control of the raster (switch on/off)
10:33 (entry 35980) MCC needs access to recover the control of the raster.
11:15 Q1 trip in the hadron arm...
11:25 Technician is in to recover Q1... it seems to be a vacuum problem; paging Ed.
12:15 Going back to beam permit
12:30 Harp scans and spot++ beam checks (OTR in) (entries #35980 #35992)
13:00 Back to data taking
13:15 MCC loose regulation control of the beam dump... no beam once again!
13:25 Troubles with the FFB in hall A
14:18 Give back beam for reduced current to check some OTR stuff, we will still
continue data taking at smaller current
14:30 Back on data taking
15:00 Give back beam to solve the trips at high current
15:15 Back on data taking at 125uA; JT valves for the target has been opened +2%
(Jt1=40.72%, Jt2=44.22%) and the remaining cryopower is 40-50W.
