A proton sensor for energies from 2MeV to 20MeV
Résumé
CNES and ONERA have developed a radiation monitor ICARE-NG (Influence sur les Composants Avancés des Radiations de l'Espace-Nouvelle Génération) to measure protons and electrons in radiation belts. This instrument is able to measure a wide range of energy for protons and electrons, but no measurements of few MeV protons are performed. The objective of this study is to extend capabilities of this radiation monitor by adding a low-energy proton sensor. In this article the design of a sensor for low-energy protons compatible with the ICARE-NG instrument is presented. Response functions for protons and electrons of the low-energy proton sensor are calculated using Monte-Carlo simulations. The calculation of predicted count rates of particles are performed. The manufacturing of the instrument as well as tests are discussed.
