Project details

Radiation is a major hazard in spaceflight.  Satellites may suffer a gradual reduction in their capabilities, including the performance of batteries, solar cells, and electronic components.  Single ion interactions in electronics (single event effects - SEE) may cause errors from memory bitflips to catastrophic, mission-ending failures. The dominant sources of radiation in space are protons and heavier ions, coming from the sun and galactic cosmic rays (GCR).  

The Heavy Ion Accelerator Facility (HIAF) at ANU is currently developing the first capability for SEE testing in Australia, able to mimic radiation environments found in space. 

This project is anticipated to involve developing a model of the primary radiation (ion species, energy, flux, LET) between low Earth and geostationary orbits for trapped protons, solar protons and heavy ions, and relating these environment to direct radiation testing on our soon to be developed space radiation testing beam line. 

Required background

This project will involve computation, including development work using Geant4, a platform for the simulation of the passage of particles through matter using Monte Carlo methods.

Proficiency with coding is essential (Python/C++).

In addition to the project outlined above, other detector modeling projects in the realm of space radiation measurment are available.

Project suitability

This research project can be tailored to suit students of the following type(s)
  • 3rd year special project
  • Honours project
  • Vacation scholar
