Continuous High-altitude Investigation of Neutron Spectra for Terrestrial Radiation Antarctic Project

The CHINSTRAP project aims at installing a high-energy extended neutron spectrometer at the Concordia station in Antarctic. The particularities of this location are unique (high altitude and proximity to the geomagnetic pole) and allow long-term measurements dedicated to the study of the atmospheric natural radiative environment dynamics for Space Weather applications. These data will complete the ones already obtained at the Pic-du-Midi in France and in the Pico dos Dias in Brazil, near the South Atlantic Anomaly.

The project includes two phases: the first consists in installing and operating the HERMEIS in the station; the second consists in investigating the data then in combining their analyses to those from other measurement sites.
