Abstract

The injector section of the LCLS machine at SLAC requires 100+ dc-magnet power supply systems for operation. Intermediate rack-mounted power supplies provide dipole, quadrupole and solenoid magnet power up to 20 kW at 375 A. A SLAC-developed Ethernet power supply controller interfaces to these commercially available power supplies. Smaller bipolar units rated 6A, 12A, and 30A provide power for small magnets such as correctors, dipoles, and quadrupoles. DACs and ADCs housed in VME crates control these power supplies. For all systems, stability requirements are better than 1000 ppm and EPICS is the controls interface. This paper describes the main hardware characteristics of the power supply systems.
