CMRP to play key role in space technology testing network

Space qualification facilities will test suitability of technology for use in space

The 榴莲视频app of 榴莲视频app (UOW) will contribute to a national network of facilities to test technology for use in space.

Space exploration missions, satellites and permanent space stations require advanced electronic instrumentation with the highest level of reliability. The physically extreme environments in space travel mean most commercially available components are unsuitable.

To ensure electronics used in space can withstand the harsh conditions, a system of certification has been developed. To obtain certification that they are 鈥渟pace ready鈥�, components have to undergo a qualification process and a rigorous series of tests.

Until now, those testing facilities haven鈥檛 been available in Australia, but a new National Space Qualification Network (NSQN) will enable local space industry organisations 鈥� and those across the Indo-Pacific region 鈥� to undergo testing in Australia.

The NSQN has received $2.5 million in funding, announced Thursday 17 June, through a Space Infrastructure Fund grant from the Federal Department of Industry, Science, Energy, and Resources.

The NSQN is a six-partner consortium led by the Australian National 榴莲视频app (ANU), and including UOW, Australian Nuclear Science and Technology Organisation (ANSTO), Steritech, Nova Systems and Saber Astronautics.

UOW will play a key role, providing a facility to test the reliability of electronic circuits and systems using laser. UOW鈥檚 contribution will be led by scientists from the Centre for Medical Radiation Physics (CMRP), which boasts an impressive track record of space industry research including collaborations with NASA and the European Space Agency.

Facility will replicate space environment

Associate Professor , CMRP Theme Leader, will lead the construction and operational aspects of the UOW NSQN node facility. He said the NSQN would provide companies with a set of facilities where all the environmental conditions in space can be replicated.

鈥淭he environment in space is so harsh,鈥� Professor Petasecca said. 鈥淭he gradient of temperature, for example, is extreme: it's minus 270 degrees one moment and then suddenly, in close proximity to Earth, it may reach 250 degrees if exposed to sunlight. Commercial electronics are not designed to work in those conditions. 

鈥淪pace craft launches also generates extreme conditions, such as vibrations and stress due to acoustics. Electronics can be severely damaged, mechanically collapsing under accelerations up to 10 Gs.鈥�

UOW will design and develop laser-based instrumentation to test electronic components ability to withstand a type of radiation damage known as a Single Event Effect (SEE).

In space, SEEs are caused most often by cosmic rays composed of high energy particles (protons, helium ions and electrons) and can play havoc with electronics, causing enough damage to jeopardise a mission.

鈥淭his SEE is accidental, it happens because of the interaction of a single particle with a functioning electronic system, but it can be catastrophic,鈥� Professor Petasecca said.

鈥淟aser light can be used to assess the probability that an electronic system will fail during a mission, mimicking the effect a radiation particle would have.鈥�

^{Professor Michael Lerch, head of the School of Physics, says UOW and the Australian National 榴莲视频app will develop a professional course in space qualification testing to train and upskill a national pool of space testing experts.}

Training a space industry workforce

Professor , head of the School of Physics, will oversee embedding the UOW node within NSQN stakeholder engagement processes and the micro-credentialing education program.

In partnership with ANU, UOW will develop a professional course in space qualification testing to train and upskill a national pool of space testing experts in order to deliver accelerated growth in the space sector and associated industries.

鈥淯OW and NSQN partners ANU and ANSTO share a long and successful history of engagement through student education and research training. Together with our industry partners we will deliver the multi-level service essential for space qualification testing,鈥� Professor Lerch said.

鈥淭he UOW NSQN node represents an exciting opportunity to pivot our expertise in semiconductor medical radiation physics towards delivering a dedicated facility that mimics space radiation impact on semiconductor components to an internationally recognised standard.

鈥淥ur NSQN industry partners will also play a critical role in building the stakeholder base that will need to utilise the UOW Node Facility, while also engaging in physics student training through work integrated learning and student placements for those with an interest in current and emerging Australian space supply chain industries that will service this global market.鈥�

World-renowned expertise in space radiation detection and instrumentation

CMRP Director Distinguished Professor will bring his world-renowned expertise in space radiation detection and instrumentation as well as scientific and industry linkages to the NASA and ESA communities to fast-track the full utilisation of the UOW and all NSQN node facilities.

鈥淣SQN has opened a great opportunity for engagement with space qualification facilities overseas,鈥� Professor Rozenfeld said.  

鈥淚n particular, with the recently created , a network of facilities and related irradiation methodology for responding to the emerging needs of electronics component and system irradiation hosted by CERN. CMRP was invited to join RADNEXT as a supporter, based on recognition of its sustained contribution to the Nuclear and Space Radiation Effects Conference and radiation detection science.

鈥淣SQN will further enhance many years of successful collaboration with ANSTO鈥檚 Centre for Accelerator Science and ANU鈥檚 Heavy Ion Accelerator facility, and open opportunity to bring international space industry customers to NSQN.

鈥淐MRP鈥檚 laser-based infrastructure facility for Single Event Upset (SEU) study in microelectronic chips will also complement CMRP鈥檚 research in radiobiological science to better understand the efficiency of proton and heavy ion therapy, because the cell killing probability with stochastic deposition of ionizing energy by traversing through the cell proton and ion is similar to SEU probability in microelectronic chip.

鈥淭his will allow development of new micro-and nano-dosimetry detectors based on SEE for the benefit of future cancer patient treatments.鈥�

^{As well as testing the suitability of components for use in space, the NSQN will train a workforce of skilled experts to grow the space sector and associated industries.}

ABOUT THE CENTRE FOR MEDICAL RADIATION PHYSICS

The Centre for Medical Radiation Physics is dedicated towards the development of semiconductor detectors and dosimeters for clinical applications in radiation protection, radiation oncology and nuclear medicine as well as high energy physics applications.

The CMRP has many years鈥� experience in radiation space research as an active member of the Nuclear and Space Radiation Effects Conference (NSREC) since 1994. NSREC recognised the high quality of its space radiation research through special awards to CMRP PhD students in 2013 and 2020. CMRP members chaired streams on radiation dosimetry and radiation testing Facility at NSREC in 2000, 2019 and 2022.

The CMRP is an active contributor to the Australian Space Program, and was a member of the Decadal Plan for Australian Space Science 2010-2019, with Professor Rozenfeld serving as a member of the Steering Committee. It is also represented in the Space Medicine and Life Sciences Technical Advisory Group of Australian Space Agency.
