    Comments: 16:15 We asked MCC to increase the current up to 70 microamperes. 17:18 Beam stopped due to injector problems and trips.. 17:24 MCC called injector people, they cannot deliver more than 50 micro Amperes. 17:50 Beam is back at 40 micro Amperes 18:09 Beam off in order to fixe it for Hall B 18.30 Magnets problems in the accelerator, magnet people on call contacted. 19:13 Magfnets problems solved in the accelerator, they are going to send beam back. 19:33 18 micro Amperes of "acceptable" beam, we start the run. 19:39 Beam off in order to tune beam for hall B. 20:18 40 micro Ampere in 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
