Abstract

To simplify the installation and speed testing of the Advanced Photon Source (APS) storage ring magnets, vacuum chambers, and magnet power supplies, a modular approach was developed. All but the dipole magnets are independently controlled. Pulsewidth-modulated DC-to-DC converters are used to power the individual magnets, with 12 pulse power supplies providing the raw DC to the converters. A magnet support base is the heart of a module and may hold as many as seven magnets with eight individually powered coils. The DC-to-DC converters are part of each magnet base module. The modular approach used for the storage ring magnet systems is described and the test results of the prototype topology for the DC-to-DC converters being built and tested to power 680 quadrupole and sextupole magnets are given
