Cosmic Ray Subsystem

       Cosmic Ray Subsystems is an instrument used in Voyager-1 and Voyager-2 spacecraft of the NASA Voyager program, and it is an experiment to detect cosmic rays. The Cosmic Ray Subsystem includes a (HETS), (LETS) and (TET). 

• High-Energy Telescope System
• Low-Energy  Telescope System
• The Electron Telescope

These instruments were designed to detect energetic particles and some the requirements were for the instruments to be reliable and to have enough charge resolution.It can also detect energetic particles from Galaxies.As of 2017 CRS is one of the active instruments on Voyager spacecraft, and it described by as being able to detect electrons from 3-110 MeV and cosmic ray nuclei 1-500 MeV/n. All the three systems used solid-state detectors. CRS is one of the five active instruments on both Voyager spacecraft, and its aim is to understand deeper about the solar-wind. Other objectives of study including electrons and nuclei from planetary magnetospheres and from outside the solar system.
