Helium and Displacement Damage Produced by 600 MeV Proton Beams in High Purity Aluminum

Source

Pure aluminium samples (99.9999%) have been irradiated in the Proton Irradiation Experiment (PIREX) installed in the 600 MeV proton beam of the accelerator in the Swiss Nuclear Research Institute (SIN), at temperatures between 400 K and 500 K and displacement doses between 0.9 and 5 displacements per atom (dpa). Average displacement rate is 3.5 × 10-6 dpa/s.

The specimens were analyzed for both 3He and 4He. Measured helium content is 215 atomic parts per million (appm)/dpa. No diffusional spreading of sodium or helium was measured. The helium bubble structure was examined and shows a swelling of 0.16% at ∼5 dpa.
