Turn-by-turn beam position measurement for 1.3 GeV booster synchrotron

摘要

A prototype turn-by-turn beam position measurement system has been implemented to characterize machine properties of 1.3 GeV booster synchrotron at SRRC. The signals picked up by button electrodes are processed by heterodyne receivers. The output of the receiver is digitized by VXI module with digitizing rate equal to the beam revolution frequency. The beam positions are calculated at embedded VXI controller under HP/UX environment. The performance of the data acquisition system and the measured data are presented.
