    keyword=Issue with Right Q1 power supply

    It seems we are missing a bit for readback current, when I ask for 1039.07 A I get 1038.598 Read back current but when I request 1039.06 A I get 1011.142 A so there is a large offset now which confuses the regulation.

    So we could run without Q1 regulation or change slightly the kinematic to avoid this spot.

    We are increasing the momentum so as to be above 1039 A.

    I checked with Doug he thinks less than 1% change should be ok and he will double check.
