Fabrication and test of prototype ring magnets for the ALS

Abstract

Prototype models for the Advanced Light Source (ALS) booster dipole, quadrupole, and sextupole and the storage ring gradient magnet, quadrupole, and sextupole have been constructed. The booster magnet prototypes have been tested. The storage ring magnets are undergoing tests and magnetic measurements. The authors review the designs and parameters for these magnet designs which respond to the special constraints imposed by the requirements for both accelerator rings, and they review some of the results of magnet measurements for the prototype.<>
