Beam Position Monitor(BPM)

Beam Position Monitors Section designs and maintains systems measuring the transverse position and phase of the various particle beams used at the normal and the superconducting LINAC in IMP. A typical BPM system is a chain of an in-vacuum electromagnetic sensor, front-end analogue RF circuit, high-speed digitizer, FPGA and back-end software. Here, the cold button BPM, the original analyzing of BPM signal, the calibrating of BPM sensors and the measured results with the real beam are presented.
