Comparison of Synchrotron Radiation Calculation between Egs4, Fluka, Photon and Stac8

With constructing and operating the third generation facilities such as SPring-8, however, high energy synchrotron radiation of extremely high intense is available, and high accuracy should be required in the shielding and safety design for the beamline of synchrotron radiation. Furthermore, the middle size facilities, such as CLS (Canadian Light Source), are now under construction and the optimum design of shielding is desired strongly to construct the beamline with safety and compact. It is necessary to verify the detailed evaluation technique. Therefore, taking the SPEAR3 ring bending magnet and BL11-3 wiggler beamlines of SSRL as the examples, the characteristics of the synchrotron radiation shielding design codes PHOTON[1] and STAC8[2] were investigated by comparing with Monte Carlo simulation codes EGS4[3],[4] and FLUKA[5].
