The Australian Nuclear Science and Technology Organisation hosts the Centre for Accelerator Science, a sovereign facility with light and heavy ion beams. The 10 MV ANTARES accelerator is equipped with one of the few Heavy Ion Nuclear Microprobes in the world, which has been upgraded with the unique External Beam Irradiation Facility (EBIF). EBIF has been actively used in the past few years for space radiation testing of electronics, advanced shielding materials, and living samples for life science in space. To align with international standards for such testing, a series of tests were performed to evaluate the uniformity of the raster scan of the microbeam across broad areas. Secondly, EBIF has been calibrated in terms of direct LET measurement by using a silicon on insulator microdosimeter developed by the Centre for Medical Radiation Physics (CMRP), University of Wollongong. Thirdly, in collaboration with researchers from CERN, energy calibration and single event effect (SEE) cross-s
Experts from internationally renowned space agencies will come together this week (12 February to 15 February) for an event hosted by the University of Wollongong (UOW) which aims to address issues including space qualification requirements, radiatio
This thesis presents research pertaining to the application of silicon microdosimetry for radiation protection and quality assurance (QA) in heavy ion therapy. Heavy ion therapy has a number of advantages compared to conventional photon therapy, particularly for treating tumours near high risk organs, due to its greater conformal energy deposition. However, successful treatment with heavy ions depends largely on knowledge of the relative biological effectiveness (RBE) of the radiation produced by primary and secondary charged particles. Sparsely ionising radiation such as x-rays, electrons and gamma rays produce approximately equivalent biological effects for the same absorbed dose. However, heavy ions produce different biological effects for the same absorbed dose. This variation in biological effect is quantified using the relative biological effectiveness (RBE).
Regional microdosimetry considers the process of stochastic energy deposition in a region comparable in size to a human ce
