The ESA Next Generation Radiation Monitor (NGRM) will be the successor of the ESA Standard Radiation Environment Monitor (SREM) that is still measuring near-Earth and interplanetary space radiation environment onboard 6 different spacecrafts. NGRM will measure protons from 2 MeV up to 200 MeV, electrons from 100keV up to 7MeV, as well as LET spectrum of ions. Compared to SREM, NGRM will provide a much better energy resolution, will be smaller (<;1L), lighter (<;1kg) and consume less energy (<;1W). In this paper we describe the detection concept of the NGRM and present the detailed Monte Carlo analysis of the performance of the NGRM detector system.

The 3DEES instrument is a space radiation spectrometer capable to measure energetic electron (and optionally proton) spectra within the 0.1 – 10 MeV range in 32 energy bins and 3D angular distribution (at least 6 angles distributed within 2 planes) with a resolution for each looking direction better than 20°. The 3DEES concept is based on various charged particle detection principles including ΔE-E telescope principle, the inclined sensor concept. Protons and ions are detected by the instrument and are so cleanly identified that they cannot contaminate the electron spectra.
The 3DEES instrument is composed of 1 – 3 Panoramic Spectrometer Modules (PSM), each of which is composed of a Docking Module (DM) to which 2 – 3 Orthogonal Sensor Modules (OSM) are electronically connected.
