3 Irradiation Facilities and Telemetry

For SEL qualification and SET characterization testing, heavy ion species were provided and delivered by the TAMU Cyclotron Radiation Effects Facility 3 using a superconducting cyclotron and advanced electron cylotorn resonance (ECR) ion source. Ion beams were delivered with high uniformity over a 1-inch diameter circular cross sectional area for the in-air station. Uniformity is achieved by magnetic defocusing. The intensity of the beam is regulated over a broad range spanning several orders of magnitude. These measurements are real-time continuous and establish dosimetry and integrated fluence. An ion flux of 105 ions / s-cm2 was used to provide heavy ion fluences to 107 ions / cm2 for most runs. Ion flux was increaded to 1.5 × 107 ions / s-cm2 for some runs, to show SEL immunity at multiple flux rates and to explore the effect of flux rate on transient event counts.
