Four Years of Measurements of the Energy Spectrum of Cosmic-Ray-induced-neutrons on the Concordia Antarctic Station Taking into Account Environmental and Systematic Effects
International audience Neutron spectrometers are operated simultaneously in the framework of a remoted network. The CHINSTRAP, supported by IPEV, aims at recording neutron spectra at the Concordia station (+3233m) in Antarctica since December 2105. The neutron spectrometer measures the neutron spect...
