Detuning of the NSLS UV RF cavity to compensate for 1 Ampere of stored beam

Abstract

A mechanically driven loop tuner in addition to water temperature variation is used to compensate f o r the reactive detuning of the 5 2 . 8 MHz RF accelerating cavity at a 1 ampere circulating current. This combination avoids the higher order resonances that occur with a single mechanical tune. System description and operating results will be detailed.
