First Successful SEE Measurements with Heavy Ions in Brazil

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.

Ag 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 15
