  • Abstract
    The present work employs MSND technology as a 3He gas-tube direct-replacement technology. The MSND-based Helium Replacement (HeRep) is a single instrument utilizing thirty 4-cm2 active area MSNDs to directly replace 3He-based proportional neutron counters. The HeRep Mk II prototype yielded 102.71±0.84% of the neutron detection efficiency of a 4-atm Reuter Stokes 3He gas-filled detector with the same active dimensions and test setup from a 252Cf source. The HeRep Mk II matched the efficiency of the 3He detector while using MSNDs that each had 20% intrinsic-efficiency for thermal-neutrons.
