BackgroundTo measure the beam positions of High Energy Photon Source (HEPS), different types of beam position monitors (BPMs) have been developed. The position sensitivity coefficient is an important parameter of BPMs by which the position of the bea

BackgroundBunch charge is the most fundamental characteristic parameter of the particle beam. The Shanghai Soft X-ray Free Electron Laser Device Facility (SXFEL) needs to add a charge feedback loop to accurately control the bunch charge and the resol

The stabilities of the beam and machine have almost the highest priority in a modern light source. Although a lot of machine parameters could be used to represent the beam quality, there lacks a single one that could indicate the global information f

The beam position monitor (BPM) system is of most importance in a light source. The capability of the BPM depends on the resolution of the system. The traditional standard deviation on the raw data method merely gives the upper limit of the resolutio
