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 an advanced Electron Cyclotron Resonance (ECR) ion source. At the fluxes used, ion beams had good flux stability and high irradiation uniformity over a 1-in diameter circular cross-sectional area for the in-air station. Uniformity is achieved by magnetic de-focusing. The flux of the beam is regulated over a broad range spanning several orders of magnitude. For the bulk of these studies, ion flux of ≈ 105 ions/cm2·s were used to provide heavy-ion fluences of ≈ 107 ions/cm2 per run.

For the experiments conducted on this report, 109Ag ions were used to achieve LETEFF 48 MeV·cm2/mg. Ion uniformity for these experiments was between 94 and 98%.

Figure 4-1 shows the TPS7H2211-SEP test board used for the experiments at the TAMU facility. Although not visible in this photo, the beam port has a 1-mil Aramica window to allow in-air testing while maintaining the vacuum within the accelerator with only minor ion energy loss. A 40-mm in-air gap between the device and the ion beam port window was maintained at these distances for all runs respective to the ion that was tested.
