Fig. 8From: Fast neutron sensitivity for 3He detectors and comparison with Boron-10 based neutron detectorsa Incident neutron energy in the detector active area for configurations (FastN) and (ThermN). The energy range 0-10 MeV is the 238Pu/Be source emission spectrum. b The counts in 0<En<0.4 eV are shown. The vertical lines represent the cut at the E2=1 MeV and E2=0.050 eV used to calculate the fast and thermal flux respectivelyBack to article page
