Abstract
A Geant4 simulation modelling the passive Biological beamline at the Heavy Ion Medical Accelerator Chiba (HIMAC) is described and validated against experimental measurements for a mono-energetic and spread out Bragg peak (SOBP) 12C beam. Comparisons to experimental data showed good agreement for both lateral and depth dose profiles. It was found that simplifying the simulation model by generating a cone beam instead of using the wobbler magnets provided a good approximation for both lateral and depth dose measurements.

Introduction12C therapy has had a growing interest thanks to its enhanced physical and biological dose properties, the 12C beam produces a complex radiation field which needs to be fully characterised for Quality Assurance
The Heavy Ion Medical Accelerator (HIMAC) at the National Institute of Radiological Sciences (NIRS), in Chiba, Japan, was the first centre to clinically treat patients with 12C and as of 2015 has treated more than 10000 patients with 12C therapy [1]

Summary
12C therapy has had a growing interest thanks to its enhanced physical and biological dose properties, the 12C beam produces a complex radiation field which needs to be fully characterised for Quality Assurance. In this work the modelling of the Biological beamline at HIMAC using Geant is described and validated against experimental measurements. This simulation model is used at the Centre for Medical Radiation Physics, University of Wollongong, to study novel detector solutions for Quality Assurance including silicon micro dosimeters [2,3,4]
