4 Irradiation Facility and Setup

The heavy-ion species used for the SEE studies on this product were provided and delivered by the TAMU Cyclotron Radiation Effects Facility and MSU Facility for Rare Isotope Beams using a superconducting cyclotron, an advanced electron cyclotron resonance (ECR) ion source and a high-power superconducting linear accelerator (LINAC). At the fluxes used, ion beams had good flux stability and high irradiation uniformity over a 1in diameter circular cross-sectional area for the in-air station. Uniformity is achieved by magnetic defocusing. The flux of the beam is regulated over a broad range spanning several orders of magnitude.

For the bulk of these studies, ion fluxes between 1E4 and 1E5 ions/s-cm2 were used to provide heavy ion fluences between 1E6 and 1E7 ions / cm2 . For these experiments Xenon (Xe) ions were used. Ion beam uniformity for all tests was in the range of 97% to 99%.
