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-section measurements were performed with a silicon diode and a commercial SRAM, which were evaluated in other international facilities. This paper discusses experimental data obtained during the tests and their comparison with GEANT4 and SRIM simulations.
