Two detectors for (n,p) and (n,α) measurements at white neutron sources

We have developed two detectors for (n,p) and (n,α) cross section measurements at white neutron sources which make possible large increases in the sample size and geometric efficiency while at the same time reducing the potentially large background associated with the “gamma flash” to manageable levels. We present measurements of two (n,α) cross sections made with these detectors to energies as high as a few MeV.
