ELDRS (enhanced low dose rate sensitivity) of electronic components is important for component operation in a low dose rate field, e.g. for satellites. Low dose rates and high total dose levels need long test duration and create high testing costs. An accelerated testing method using switching of high and low dose rates has been investigated. Statistical analysis has been performed to decrease test sample size.

RADFET is a small type of integrating dosimeter based on a field effect transistor. The radiation response to photons, electrons, protons and neutrons of different energies has been modelled with Monte Carlo simulation (FLUKA, GEANT4) and compared to experimental measurements.

The performance of graded shielding of aluminium, lead and tantalum in energetic electron fields is investigated. Monte Carlo codes simulations using FLUKA and GEANT4 are compared with experimental measurements (5 MeV - 50 MeV). The results will be used for ESA’s Jupiter Icy Moons Explorer (JUICE) mission.
