Electron beam diagnostics using synchrotron radiation at the Advanced Light Source
Synchrotron light emitted from a bend magnet is being used to diagnose the electron beam stored in the main accelerator of the Advanced Light Source (ALS) at Berkeley Lab. The radiation has maximum intensity in the soft X-ray region and is imaged by a Kirkpatrick-Baez mirror pair from the source point inside the ring onto a Bismuth/Germanium-Oxide (BGO) crystal, converted into visible light and magnified by an attached microscope. The final image is captured by a TV camera-tube and digitized by a frame- grabber device to obtain records of parameters such as beam size, center location and profile. Data obtained from this Diagnostic Beam Line have been very useful in day-to-day operation of the ALS storage ring to assess the quality and repeatability of the stored beam. The line has further been utilized in several dedicated research activities to measure bunch lengths under various conditions and observe transverse beam instabilities. A summary of obtained results is given in this paper , together with a description of the technical features of the Diagnostic Beam Line.
