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 defocusing. The flux of the beam is regulated over a broad range spanning several orders of magnitude. For these studies, ion flux of 1.02 × 104 to 1.12 × 105 ions / cm2 × s were used to provide heavy-ion fluences of 9.97 × 106 to 1.00 × 107 ions / cm2.

For the experiments conducted on this report, there were three ions used, 109Ag, 141Pr, and 165Ho. 109Ag was used to obtain LETEFF of 48 MeV × cm2 / mg. 141Pr was used to obtain LETEFF of 65 MeV × cm2 / mg. 165Ho was used to obtain LETEFF of 75 MeV × cm2 / mg. The total kinetic energies for each of the ions were:

  • 109Ag = 1.634 GeV (15 MeV/nucleon)
    • Ion uniformity for these experiments was 94%
  • 141Pr = 2.114 GeV (15 MeV / nucleon)
    • Ion uniformity for these experiments was between 86 and 94%
  • 165Ho = 2.474 GeV (15 MeV / nucleon)
    • Ion uniformity for these experiments was between 88 and 92%

Figure 4-1 shows the TPS7H6003-SP Evaluation Board used for the data collection 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 mm for all runs.
