Abstract

The Stanford Synchrotron Radiation Laboratory (SSRL) successfully commissioned a 3-3.5-GeV electron injector for the SPEAR storage ring during 1990. The injector operates at a 10-Hz repetition rate and accelerates approximately=10/sup 10/ electrons/s for extraction and transport to SPEAR. The extraction septum magnet is a pulsed Lambertson type which, for reasons of economy, was constructed from the same laminations which form 1/2 of an injector booster synchrotron dipole magnet core block. The excitation coil also utilizes a design in common with the pulse chokes of the booster magnet circuit. The septum magnet is pulsed by an SCR controlled resonant LC circuit with a resonant frequency of 30 Hz.<>
