Hydrogen and helium production cross sections for 15-MeV neutrons on types 316 and 304 stainless steel
Hydrogen and helium production cross sections have been measured for 15-MeV neutrons incident on Types 316 and 304 stainless steel. A charged-particle magnetic-quadrupole spectrometer was used to measure the (n,xp), (n,xd), and (n,x..cap alpha..) cross sections and the charged-particle spectra. The measured gas production cross sections, 260 +- 38 mb for hydrogen and 48 +- 7 mb for helium, differ by as much as 73 percent from those used in previous assessments of candidate materials for fusion reactors. The energy spectrum of recoil nuclei from (n,x..cap alpha..) reactions, deduced here directly from the alpha-particle spectra, also differs from calculated spectra used in predicting displacement damage.
