16:15 we asked for 70 micro Amperes.
16:45 We have 75 micro amperes!
17:18 Beam stoppped during run # 1398 because of problems in the injector.
17:24 MCC called injector people to discuss problems, now they cannot deliver more then 50 micro Amperes.
17:29 MCC cannot deliver more than 30 micro Amperes, Injector on called have been contacted.
17:50 Beam is back at 40 micro Amperes.
18:09 Beam is off in order to fix it for hall B.
18:30 Magnets problems in the accelerator, magnet people on call contacted.
19:13 Magnets problems fixed in the accelerator, they are going to tune the beam and give CW.
19:28 Beam is back: 18 micro Amperes when making harp scans in Hall B. If things
are good, Mcc will try to deliver 40 micro Amperes.
19:39 Beam off for tuning in Hall B.
20:18 40 micro Amperes beam inb the hall.
22:00 We finished Q2 = 15.00 and change the target to 12C with raster OFF
22:12 End 12C run for Helium at Q2=15.00, start change of configuration for E-arm at 68.45 deg and momentum 708.15 MeV/c
