The single event effects (SEEs) sensitivity of the HAS2 CMOS image sensor has been characterized with protons, electrons, and heavy ions. The read-out integrated circuit (ROIC) of the sensor was found to be sensitive to charged particle-induced upset. Vulnerable elements of the ROIC were identified by the analysis of image corruption events under beam. The charge collected from the passage of protons and electrons in the photosensitive zone has also been measured and compared to the results of Monte Carlo simulations. The charge collection depth of the sensor was found to differ significantly from the epitaxial layer thickness of the device. © 2013 IEEE. Source

Two European GaAs power P-HEMT MMIC processes using representative test structures have been characterized in situ when irradiated by high energy heavy ion radiation beam (420 MeV Xenon source, LET = 46.6 MeV cm2/mg), and under various worst case bias including DC and high drive RF conditions applied. The test methodology conducted has been carefully defined in order to help to early discriminate failure mechanisms induced by biasing stresses from those possibly induced by heavy ion irradiation environment. It is demonstrated that the two P-HEMT processes tested under worst case application biasing conditions (both cumulated DC and RF) are immune to heavy ion radiation stress representative of harsh space environments. © 2013 Elsevier Ltd.

Displacement damage dose was measured over 26 months on the CARMEN-2 experiment using the feedback loop of an Optically Stimulated Luminescence (OSL) sensor. These in-flight results are analyzed and discussed addressing the issue of temperature dependence and energy correction. A comparison between in-flight data and ground tests measurement validates this method. © 2011 IEEE. Source
