Heavy Ion Testing With Iron at 1 GeV/amu

A 1 GeV/amu
⁵⁶
Fe ion beam allows for true 90° tilt irradiations of various microelectronic components and reveals relevant upset trends at the GCR flux energy peak. Three SRAMs and an SRAM-based FPGA evaluated at the NASA Space Radiation Effects Laboratory demonstrate that a 90° tilt irradiation yields a unique device response. These tilt angle effects need to be screened for, and if found, pursued with radiation transport simulations to quantify their impact on event rate calculations.
