Over the years, much effort has been devoted to Monte Carlo simulations of different accelerators. A comparison of the derived parameters from previous publications concerning Monte Carlo modelling of Varian accelerators and this work is listed in the Table 1 below. Sheikh-Bagheri and Rogers [7]have probably performed the most comprehensive study and they concluded that the two most important parameters for simulating photon beams is the mean energy and the radial intensity distribution of the incident electron beam
