Master's thesis of Applied Science (Medical and Health Physics): Monte Carlo evaluation of the dosimetric uncertainty in matched 6 MV Elekta and Varian linear accelerators

The aim of this thesis is to ensure that accurate calibration factors are provided to radiotherapy clinics when moving to the new linac-based primary standard calibrations. Specifically, this thesis quantifies the error introduced when using a calibration factor from the ARPANSA Elekta linac on a Varian high energy platform beam at 6 MV.
