Description

The EGS4 electron-photon Monte Carlo code has been used to study the characteristics of the bremsstrahlung x-rays generated from the interaction of circulating electrons with the residual gas in accelerator storage rings. Gas bremsstrahlung dose rates are given for various opening angles as a function of the electron beam energy ranging from 0.5--10 GeV. Photon and neutron dose rates, generated from various devices struck by gas bremsstrahlung in a synchrotron radiation beamline, are also presented along with the photon spectral and transmission results. The EGS4-predicted results are found to be in basic agreement with the measurements made at the Stanford … continued below

Figures, equations, and a simple method useful for the photon-neutron shielding design for beamlines are provided.
