A large area detector for neutrons between 2 and 100 MeV

Abstract: A neutron detector sensitive from 2 to 100 MeV is described. neutron/cm -sec at a counting rate of one per minute, the energy resolution is 12% at 15 MeV and 30% at 100 MeV. The angle between the incoming neutron and the recoil neutron is measured to ± 10 .

“…Until better neutron detecting systems are flown (e.g. Grannan et al, 1972 andFriling, 1972), the upper limits set for this energy region will remain large. It is to be noted that all the observations of neutrons with E> 20 MeV are orders of magnitude greater than the calculated fluxes of Roelof (1966) assuming that all the low energy 'quiet-time' (< 50 MeV) protons are the results of solar neutron decay and that the protons diffuse isotropically through the interplanetary region.…”

“…Thus, a detecting system with a large geometrical factor might be able to observe the time-dependent energy for solar neutrons. For example, with the large proton-recoil detector proposed by White (1968) and developed by Grannan et al (1972) the minimum detectable neutron flux at 25-50 MeV is ~2 x 10 -6 neutrons cm -2 s -1 MeV -1. This corresponds to the peak solar neutron flux for Po = 125 MV in Figure 8.…”

“…It had a threshold at 50 MeV and an efficiency of 0.1~ at 100 MeV. The UCR group achieved a significantly lower threshold of 2 MeV with a double layer of liquid scintillator cells where the first scatter took place in one layer and the second scatter in the other layer (Grannan et al, 1972). The maximum efficiency of 8~o occurs at 5 MeV falling to 0.4~o at 100 MeV.…”
