Comments: 16:44 Quadrupoles 1 for right and left HRS tripped. Asked MCC for an access 17:10: Q1s fixed 17:27 beam back. 21:00 Done with kinematics ep4-3. New kinematics: HRS left is now at 1.687 GeV/c HRS right is now at 3.064 GeV (Q2 and Q3 cycled) We moved left HRS to 43.604 We moved right HRS to 22.318 We opened the 1.5" and 3" FPP carbon doors 21:54. Beam back (20 uA). 22:50 quadrupoles Q1 or left and right HRS tripped. Need controled access to reset them. 23:34. Beam back.
