objective: using megavoltage photons generated by medical linear accelerator is a common modality for the treatment of malignant. the crucial problem for using photon beams >8mv is the photoneutron yields that increase the risk of secondary cancer that treated with high-energy photon beams. the contaminated neutrons produced in different components of the accelerator head and rely on many param...

Simulation software for medical linear accelerators that can be used in a teaching environment was developed. The components of linear accelerators were modeled to first order accuracy using analytical expressions taken from the literature. The expressions used constants that were empirically set such that realistic response could be expected. These expressions were programmed in a MATLAB envir...

The status of PAMELA (Particle Accelerator for MEdical Applications) – an accelerator for proton and light ion therapy using a non-scaling FFAG (ns-FFAG) accelerator – is reviewed and discussed.

Medical accelerators require arc-free operation. Due to high-field emission, arcing and outgassing can occur in high-power accelerators. Therefore, the accelerator’s inner surfaces have to be conditioned before its use at high gradient levels in Radiation Therapy machines. At Siemens, we have developed a technique to automatically condition accelerator structures by continually inspecting the a...
