Ion-beam profiling of /sup 3/He in tritium-exposed type 304L and type 21-6-9 stainless steels
The nuclear reaction /sup 3/He (d,p) /sup 4/He was used to determine /sup 3/He depth profiles in high-energy-rateforged Type 304L and Type 21-6-9 stainless steels following exposure to tritium. A sensitivity to /sup 3/He better than 1 atomic ppm and a depth resolution of about 0.5 ..mu..m were achieved. The /sup 3/He decay product provides an essentially immobile trace of the diffusing tritium, and as a result tritium diffusivity and solubility may be calculated from the measured /sup 3/He distribution. Tritium exposure in these experiments occurred at 343 K under 45 MPa partial pressure. The diffusion coefficient obtained at 343 K was (1.6 + or - 0.3) X 10/sup -9/ mm/sup 2/ per second in both steels, while the solubility at 45 MPa partial pressure was 3700 + or - 900 atomic ppm for Type 304L and 7500 + or - 1900 atomic ppm for Type 21-6-9.
