Oral presentation

Space environment is a mixed environment where ions, protons and electrons coexist, with energies from a few keV to a few hundred MeV. Most radiation monitors used to measure fluxes in the space environment are based on solid-state detectors (SSD). These instruments use the total energy deposited in a sensitive volume by a particle to identify its nature and incident energy. However, protons...

Oral presentation

HEPI is a new instrument developed to measure >300 MeV/nuc particles in a very small (‘< 1U’) package which would be suitable for a CubeSat mission as well as for hosting on larger missions. It uses the principle of Cherenkov radiation which is one of the earliest techniques used in space radiation measurements, for example the cosmic ray detector on the first UK satellite, Ariel-1. Although...
