Instrument details
Acronym
NGRM
Full name
Next Generation Radiation Monitor
Purpose
For Space Weather. NGRM measures protons from 2 MeV up to 200 MeV, electrons from 100 keV up to 7 MeV as well as the Linear Energy Transfer spectrum of ions.
Short description
Direction sensitive particle spectroscopy for:
- electrons (e-) in the energy ranges of 0.1 to 7 MeV; 8 quasi-logarithmic channels
- protons (p+) in the energy ranges 2 to 200 MeV; 8 quasi-logarithmic channels
- Heavy Ions: LET spectrum 0.1 to 10 MeV cm²/mg; 8 quasi-logarithmic channels.
