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 using a superconducting cyclotron and advanced electron cyclotron resonance (ECR) ion source. Ion beams are delivered with high uniformity over a 1-inch diameter circular cross-sectional area for the in-air station. Uniformity is achieved by means of magnetic defocusing. The intensity of the beam is regulated over a broad range spanning several orders of magnitude. For the bulk of these studies, ion fluxes between 10⁴ and 10⁵ ions/s-cm² were used to provide heavy ion fluences between 10⁶ and 10⁷ ions/cm². For these experiments Silver (Ag) ions were used. Ion beam uniformity for all tests was in the range of 91% to 98%.
