SAFIIRA: A heavy-ion multi-purpose irradiation facility in Brazil

Abstract: This work describes the new facility for applied nuclear physics at the University of Sao Paulo, mainly for irradiation of electronic devices. It is a setup composed of a quadrupole doublet for beam focusing/defocusing plus multiple scattering through gold foils to produce low intensity, large-area, and high-uniformity heavy-ion beams from 1H to 107Ag. Beam intensities can be easily adjusted from 102 particles cm2/s to hundreds of nA for an area as large as 2.0 cm2 and uniformity better than 90%. Its irradiati… Show more

“…The heavy ions accelerated irradiation experiments were performed using the SAFIIRA [20] test setup dedicated to electronic devices qualification at the tandem electrostatic 8 MeV Pelletron accelerator of the LAFN-USP facility, Brazil. In this setup, the beam is produced by multiple collimations, defocusing and scattering by thin gold foils, achieving high uniformity, large area and very low particle fluxes in the range from 10 2 to 10 5 particles/cm 2 /s.…”

“…Two heavy ion irradition campains were performed on the fault tolerant DAS at the Laboratório Aberto de Física Nuclear at the Universidade de São Paulo (LAFN-USP), Brazil [31], with ion beams produced and accelerated by the São Paulo 8UD Pelletron Accelerator, generating a 16 O ion beam with 22 µm penetration into the silicon. The heavy-ion beam was accelerated up to 36 MeV and reduced its intensity to hundred particles/s/cm² (as recommended by the European Space Agency (ESA) for SEU tests [32]) using magnetic defocusing techniques and two thin gold foils (near 1 mg/cm²) in the SAFIIRA system [33]. This new system was built to study heavy-ion beam effects in electronic components.…”
