    keyword=[Target] Magnetic Field Moved Again

    We have again seen the magnet power supply ramp up, turn on the heater and move the current in the magnet down by 0.5A on its own initiative. This is the first time this behavior has been seen with 100nA beam. The movement killed the polarization and stopped a production run.

    We have lifted the field back up and are continuing with polarization. This PS has been known to do this in the past, and the target group pursuing a solution.
