Design and operational experience of FRIB magnet and electrostatic power supplies

This paper will present design principles, procurement strategies, installation and testing plans, and availability data from commissioning and operation of over 1500 magnet and electrostatic power supplies at the Facility of Rare Isotope Beams (FRIB). This paper introduces the types of power supplies required for the FRIB which range in size from electrostatic high voltage power supplies less than 1 Watt to 150 kW magnet power supplies. The power supplies range in complexity from simple single quadrant units to four-quadrant pulsed electrostatic high voltage units to units requiring complex auxiliary equipment. Stability requirements of these power supplies range from 10 ppm for some sensitive experimental equipment to 3000 ppm for some multipole magnets.
