Radiation Effects and Industrial Applications

The group specializes in applied research on nuclear- and accelerator-based technology and operates the Radiation Effects Facility, RADEF, for the studies of radiation effects in electronics and related materials. RADEF has been an ESA supported European Component Irradiation Facility (ECIF) since 2005. Since then irradiation tests have been carried out not only for ESA and the Euro­pean space industry, but also for other world leading space organizations (e.g. NASA, JAXA, CNES), institutes, companies and universities.

Research group description

RADEF’s specialty is to provide high penetration heavy ion cocktail beams, protons in wide energy range and energetic electrons. For these the RADEF group utilizes combination of JYFL's ECR ion sources and K-130 cyclotron, and the LINAC electron accelerator. Because the emerging technologies make integrated circuits more susceptible to radiation, the group is expanding its research activities toward the radiation effects in avionics and ground level systems.
