Beam Position Monitoring in Electron Accelerators

摘要

Beam Position Monitoring (BPM) systems are crucial in particle acceleration facilities for maintaining stable movement of the beam. Beam displacement, information about synchrotron oscillations and betatron movements can be derived from data gathered in BPM systems. Medical electron accelerators also employ BPM measurements to ensure optimal generation of treatment radiation. The article gives an overview about electron beam characteristics, BPM concepts and signal processing methods used in particle accelerators. Moreover, experimental results on electron beam position are presented.
