On shift: SL: Elena Long TO: Robert Michaels
08:00 Shift starts Continuing taking data at Kinematics 1, delta=+2%
09:06 Noticed abnormalities in reference data during replay, made log about it (Logs #241699 and #241700)
09:36 Run 2074 data matches that of the reference data, made log (#241703 and #241705)
12:05 Runs continue to have the spike in them
13:54 Escorted Access requested to change to Kinematics 3, delta=+2% Guy and Brad entered hall once access was permitted to change BB angle Cycled quads Q2 and Q3 P0 changed to 0.6955 GeV/c Left Arm moved to 53.002 degrees 0.75'' and 3'' FPP Carbon Doors in place BigBite moved to 35 degrees Target changed to 6cm LH2 Kinematics changed to 3, delta=+2%
14:30 BB Configuration runs taken
14:49 Target changed to 6cm Al Dummy, beam set to 20uA
15:11 Target changed to 6cm LH2, beam set to 8uA, production data taking begins Data continues to have the U1 spike discussed earlier (reference 09:06-12:05)
15:56 Production data taking continues to end of shift
