Comments: 16:51 Done data taking for FPP straight through. Start data taking for c12 target alignment study. 17:18 Controled access (push the FPP doors back in and fixed Q1 right arm) 17:55 back to beam permit 19:35 Finish tuning thru the compton chicane. We go in controled access because quadrupole Q1 on right HRS tripped again. 19:50 Q1 fixed. Back to beam permit. 20:42. Beam is back but the optic target is still causing beam trips (from the beam dump ion chambers) 21:52 We give up for now the c12 optic data and go to LH2 Problem with the eP ion chamber (beam trips). MCC retuned the beam 22:21 beam available for physics data taking. 23:03 Beam trip. Need to retune the beam. 23:45. Beam is back
