4 Irradiation Facility and Setup

The heavy-ion species used for the SEE studies on this product were provided and delivered by the Texas A&M University (TAMU) Cyclotron Radiation Effects Facility using a superconducting cyclotron and an advanced electron cyclotron resonance (ECR) ion source. At the fluxes used, the ion beams had good flux stability and high irradiation uniformity over a one inch 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 majority of these studies, ion flux of 105 ions / cm2 × s were used to provide heavy-ion fluences of approximately 107 ions / cm2.

For the experiments conducted in this report, the following ions and corresponding angles were used to provide a range of LETEFF of 48 MeV × cm2 / mg.

  • Silver (109Ag) at 0° for an LETEFF = 48 MeV
    • RangeEFF = 91.2 µm
    • Total Kinetic Energy = 1.634 GeV (15 MeV / nucleon)

Ion uniformity for these experiments was between 93 and 96%.

Figure 4-1 shows the TPS7H2140-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. The in-air gap between the device and the ion beam port window was maintained at 40 millimeters for all runs.
