keyword=left dipole ramping down
Todd Ewing got a call that the Left Dipole was ramping down. When we observed the failure mode it appeared that the field regulator software had stopped working, and the magnet was settling into the recently discovered offset between the set to current and the readback (which varies as a function of current output, with no offset up to 100 amps, increasing to approximately 60A at 1KA output, and seems to be a linear effect.
