Abstract

This paper describes the types and quantities of dc and pulsed magnet power supplies required for the Spallation Neutron Source (SNS) Linear Accelerator: High-Energy Beam Transport (HEBT), Ring and the Ring-to-Target Beam Transfer (RTBT). There are over 600 magnets and more than 550 magnet power supplies. These magnet power supplies range in size from the bipolar corrector supplies rated at 35 volts, 20 amps to the main-ring dipole supply that is rated at 440 volts, 6000 amps. The Linac power supplies have a ripple/stability specification of 1000 parts per million while the ring supplies have a specification of 100 parts per million. There are also pulsed-power supplies for beam injection and beam extraction. The paper will show acceptance test results from the manufacturers as well as test results performed by the SNS magnet power supply group.
