title: A control system of a negative hydrogen ion sources by using an EPICS-based proportional-integral-derivative.
abstract: We have developed an EPICS-based control system for a multicusp negative ion source based on a VME IOC software, a sequencer controlling a closed proportional integral (PI) loop, and an interlock. The PI loop was tuned by a step input voltage, and tuning gains of the proportion and integral have been determined. The PI logics, developed by using standard proportional-integral-derivative records, can control the arc current within +/-1% of a given set value.
