    keyword=Right dipole power supply in strange state

    Right dipole power supply in strange state. Note the fact that there is current yet the Power Supply reads "OFF" and Magnet "DISENGAGED" (both still in green).

    It had been ramping up to a manually-set current of ~30 amps but stalled around 21.78A. Then it started to slowly ramp down regardless of the set point. The "0 Amps" button was pressed with hopes that it would speed up the ramp rate, but no luck. The magnet is ramping down at roughly 0.01 A/second.
