BEAM INSTRUMENTATION USING BPM SYSTEM OF THE SPring-8 LINAC

Beam position monitors were installed in a SPring-8 linac’s dispersive sections, and the entire beam trajectory could be measured along the linac. A fast and synchronized accumulating database system started, that accumulated beam position data from all forty-seven BPMs simultaneously at 10-pps operation of the linac. Feedback control of steering magnets and an energy compression system for beam position stabilization were also successfully examined.
