Commercial Services
- Space radiation dosimetry and radiation monitoring instrumentation
- Radiation Assurance of electronic components for Space applications
- Radiation Protection simulation studies
Overview
The Centre for Medical Radiation Physics (CMRP), directed by Distinguished Professor Anatoly Rozenfeld , is an internationally recognised for the development of semiconductor radiation detectors used in dosimetry of ionizing radiation in mixed radiation field environments.
Space relevant research focus areas
- Development of a series of semiconductor microdosimeters measuring ionizing energy deposited on a cellular level and other sensors for dose equivalent measurements for astronauts and predicting of Single Event Upset (SEU) in microelectronics in space radiation environment.
- Research and application of microdosimeters in medical charged particle therapy accelerator facilities for characterisation of radiation fields mimicking space environments; used for testing of space electronics. Microdosimetry research is supported via ARC, NHMRC and NASA (National Space Biomedical Research Institute) grants.
- Development of mixed field radiation monitoring systems (photons, protons and neutrons)
Collaboration
The CMRP is an active member of IEEE Nuclear Space Radiation Effects (NSREC) and the European RADiation EffECtS (RADECS) communities with strong expertise in testing of semiconductor devices at radiation accelerator facilities mimicking space radiation environment (e.g. NIRS, NSRL (BNL), LLUMC).

Overview
Professor Marco Petasecca provides a commercial irradiation service for characterisation of the sensitivity of integrated circuits to Single Event Effects (SEU and SEL) using a tunable pulsed laser source which raster scans the surface of the device under test, injecting a finely controlled energy pulse up to 30 nJ/pulse. A detailed table (see in the pictures folder) specifies all the parameters and their range of operation of the optical test bench.
The instrumentation has been developed within the National Space Qualification Network (NSQN), funded by the Space Infrastructure Fund scheme.
The laser technique is particularly useful for debugging of instrumentation designed to qualify electronic components meant to be tested using accelerated particles such as protons and heavy ions.
The beam positioning, intensity and environmental parameters are controlled by dedicated data loggers and correlated with the output of the device under test for characterisation of its radiation hardness in specific points of the circuit. The technique requires the physical decapsulation and exposure of the die of the integrated circuit. This service is arranged for the customer as part of the services available within the NSQN.
Overview
Geant4 is a Monte Carlo Simulation Toolkit which calculates the energy deposition due to transport of radiation particles in matter. This tool is useful to simulate radiation doses for astronauts and spacecraft components in the space radiation environment for Earth orbits and deep space environments.
Space relevant research focus areas
- Research on the improvement of Monte Carlo (Geant 4 and Geant DNA) code for dose deposition in silicon nanoscale electronics for SEU prediction.
- Research and development of radiation protectors (in collaboration with the UOW Institute for Superconducting and Electronic Materials) for astronauts based on innovative nanoparticles acting as scavengers for radiation oxygen spices (ROS) for humans in space missions.
