08:00 Start of Day Shift (setting #12 was at 500mC) 11:00 Stop setting #12 with run 2461. We move spectrometer, change its momentum, change target from LH2 4cm to LH2 15cm. 11:20 Start several runs in order to know if we can use LH2 15cm. And if we can, with how much beam current. 12:00 We decided to run with LH2 15cm under 35uA with a goal 190mC. (First run 2462, the 2464 run crashed 13:30 White alarm appeared on hall A alarm. I made an emtry in logbook. It tells that MF2 Alarm and MF7 Alarm are not connected. We finish run with LH2 15cm. Now we also start calibration run with Al 15cm. 14:00 Switch the target to Al 4cm for calibration run. 14:10 Coda crashed. 2474 JUNK 14:45 After 30-35min (need to reboot several rocs), Coda started working. We started an other calibration run with Aluminium 4cm. 15:45 Start production with LH2 4cm with 80uA.
