We report on experimental SEU studies using thermal and high-energy neutrons, conducted at the TRIUMF facility, Vancouver. Different SRAM samples were used and many samples showed to be highly susceptible to thermal neutrons. Moreover, a considerable part of the total SEU-rate, at high altitudes as well as down at sea level, may be attributed to thermal neutrons for RAM based devices View full abstract»
