keyword=LHRS Q1 fluctuations, unresolvedHave been unable to resolve the fluctuations in the left Q1 current/momentum. Things I tried:
Turning off regulation, set current 5 A above setpoint, turn regulation back on
Turning off regulation, set current 5 A below setpoint, turn regulation back on
Moving entire left arm to 0.9 and back to 0.8703
the frequent "magnet mismatch" state was not present at the previous momentum setting (first figure). The fluctuation in momentum is +-0.1% (0.8703 -> 0.8715), small, so we are probably ok. But should be investigated in the morning I guess.
