Introdution: The aim of this study was to evaluate and benchmark EGSnrc code in the simulation of 18 MV photon beam produced by Siemens Oncor® linear accelerator. Methods: This study was conducted in a comparative and simulation based on experience method. The Beamnrc code was used to model the accelerator head and generate phase space files. The phase space files were obtained with the fo...

introduction: in clinical electron beams, most of bremsstrahlung radiation is produced by various linac head structures. this bremsstrahlung radiation dose is influenced by the geometry and construction of every component of the linac treatment head structures. thus, it can be expected that the amount of the contaminated photon dose due to bremsstrahlung radiation varies among different linacs,...

Five new accelerating modules were installed into the TTF tunnel as a part of the VUV FEL Linac. They are tested prior to the linac operation. The RF test includes processing of the superconducting cavities, as well as maximum module performance tests. The test procedure and the achieved modules cavities performance are presented. Abstract Five new accelerating modules were installed into the T...
