8th European Workshop on Radiation Effects on Components and Systems, Univ Jyvaskyla, Dept Phys, Jyvaskyla, FINLAND, SEP 10-12, 2008International audienceWe report real-time SER characterization of CMOS 65 nm SRAM memories in both altitude and underground environments. Neutron and alpha-particle SERs are compared with data obtained from accelerated tests and values previously measured for CMOS 130 nm technology

Nematic liquid crystals can be electrically addressed when sandwiched in thin layers. We present in this paper a liquid crystal optical data composer which is X-Y addressed using the electro-optical effect of index modulation, a field effect, realised for an a. c. electric field on an homeotropic structure. It is a 128 x 128 dots display capable of presenting at the same time 1.6 x 104 digital optical data, with overall writing times of a few milliseconds
