Monte Carlo simulation of BEPC II beam-related background (I) - Synchrotron radiation

Synchrotron Radiation (SR) photons are generated when beam particles of BEPC II undergo the acceleration in magnetic fields of dipoles and quadrupoles. Three programs, SRGEN, SRSIM and EGS are used to simulate the SR spectra, power deposition and the background of SR in detectors of BES III due to the interaction of SR with the material of beam pipe etc.
