Avalanche Mode Resistive Plate Chamber Early Developed

The thesis of Research of Avalanche Mode Resistive Plate Chamber (RPC) is the self-made subject by CAS Institute of High Energy Physics. The name of thesis is the Research of Avalanche Mode Resistive Plate Chamber (RPC), the work of this topic is the Research and Performance Test of Electromagnetic Calorimeter in testing beam.The research of avalanche mode Resistive Plate Chamber detcctor (RPC) can be applied to various large particle physics experiment devices, including sampling calorimeter andμparticle detector, the streamer mode RPC is used byμ-identifiers in BESIII at present. However, with the high collision energy and frequency of Particle Collider, the density of collision tip particle and count rate goes up, In the streamer mode, because of the strong Streamer Discharge signal, long recover time, count rate can bearing too low, which can't meet the requirement of Collider, but the Resistive Plate Chamber in avalanche mode can do.Testing beam is an important means of testing various detectors including the RPC. The trial aim mainly at adjusting internal structure of BGO crystal calorimeter by the Performance parameters of Uniformity, Linear energy, Energy Resolution and Two-particle identification, so we can develop the Electromagnetic calorimeter that Meet the special requirements in testing beam, raised the Single-particle identification capability of BEPCII (Beijing Electron Positron Collider) in the beam test and enhanced the level of beam performance test to various particle detectors, which laid a solid foundation for the performance test of Avalanche Mode Resistive Plate Chamber detcctor in testing beam.
