Sensitivity of proton single event effect simulation tool to variation of input parameters

The sensitivities of a Monte Carlo simulation tool (PRESTAGE) to variation of input parameters are studied. When calculating the single event upset cross-section induced by proton direct ionization, PRESTAGE calculation results significantly change with changes in the sensitive volume and passivation layer thicknesses. When calculating cross-sections induced by proton indirect ionizations, PRESTAGE is not sensitive to the change of the passivation over layer thickness, and the calculation results stay constant as the thickness of the sensitive volume varies within the range of 0.05~2 μm. In other ranges, the calculated cross-section decreases with the increasing of the sensitive volume thickness. These study results provide important references for the engineering application of PRESTAGE.
