The use of an optoelectronic semiconductor for monitoring electron beam position at the Daresbury Synchrotron Radiation Source

Abstract

An important requirement of all synchroton radiation sources is the ability to determine accurately the electron beam position stability. This has now been demonstrated at the Daresbury Synchrotron Radiation Source (SRS) with a solid state detector that monitors the visible synchrotron radiation emitted by the stored electron beam. The device is a commercially supplied, single element, optoelectronic sensor that provides continuous position data of a light spot incident upon its surface. Design and development of the signal processing is discussed together with its experimental performance. Some typical results of electron beam stability on the SRS are also presented.
