FaNS: A Fast Neutron Spectrometer for the Bexus 30/31 campaign — •Hauke Jacobsen, Goerkem Bilgin, Stephan Boettcher, Bernd Heber, Malte Hoerloeck, Friedericke Schattke, and Carsten Wallmann — Christian-Albrechts-Universität Kiel

The interaction of primary cosmic rays with the molecules of the Earth’s atmosphere leads to a complex radiation field which consists among others of neutrons. The Fast Neutron Spectrometer (FaNS) has been developed to determine the flux of fast neutrons within the Earth’s atmosphere. The instrument consists out of a boron-doped plastic scintillator which is optimized for the energy range from about 0.5 MeV to above 10 MeV. Here we present a description of the measurement concept for a compact instrument that can be flown on weather balloons and aircraft and corresponding results of a GEANT 4 simulation.
