    Shift Workers: Chao Gu(SL), Melissa Cummings(TO), Eric Jensen(3rd)

    00:00 Shift starts. We were doing Septa scan to decide the proper current for this new configuration 01:00 We finished the septa scan and start the delta scan. 01:15 Set LHRS momentum to 1% 01:35 Set LHRS momentum to 2% 01:50 Set LHRS momentum to 3% 01:55 Set RHRS momentum to 2% 02:10 Set LHRS momentum to 4% 02:45 Set RHRS momentum to 3.5% 02:50 Cycled LHRS Q2, Q3, then set LHRS momentum to -4% 03:05 Set LHRS momentum to -3% 03:35 Set LHRS momentum to -2% 04:00 Cycled LHRS Q2, Q3, then set RHRS momentum to -3.5% 04:00 Set LHRS momentum to -1% 04:00 Melissa found there is LHe in the target nose 04:50 Dustin came and fixed the LHe issue 05:20 Set RHRS momentum to -2% 05:35 Delta scan finished, set both arms momentum back to 0% 05:50 When we are waiting for the right arm dipole settled, I took 2 3rd arm run to decide the slow raster size with fast raster on (we forgot to do this during beam recovery). The recommended value is 1.0V. 06:00 Start to do the beam position scan 07:20 Finished beam position scan. We start to take 2 quick run for acceptance study. 07:35 Start to put the LHe back to target nose 08:00 Shift ends. We finished pointing. Optics is finished.
