First Successful SEE Measurements with Heavy Ions in Brazil

Abstract

In this work, the first successful SEE measurements with heavy ions in Brazil is reported. The heavy ions were produced at the São Paulo 8 UD Pelletron accelerator. ¹²C, ¹⁶O, ¹⁹F, ²⁸Si, ³⁵Cl, ⁶³Cu and ¹⁰⁷Ag heavy ion beams were used to test a commercial off-the-shelf transistor. During irradiation, the response of a pMOS transistor was continuously monitored to measure the SEE events. In order to achieve a uniform low intensity beam the heavy ions were Rutherford scattered at 15⁰ by a 275 μg/cm² gold foil.
