particle detector
instruments to detect this radiation commonly measure the cherenkov radiation produced by secondary particles generated from an energetic photon entering the earth's atmosphere. this method is called imaging atmospheric cherenkov technique or iact. a high-energy photon produces a cone of light confined to 1° of the original photon direction. about 10,000 m of the earth's surface is lit by each cone of light. a flux of 10 photons per square meter per second can be detected with current technology, provided the energy is above 0.1 tev. instruments include the planned cherenkov telescope array, gt-48 in crimea, magic on la palma, high energy stereoscopic system (hess) in namibia veritas and chicago air shower array which closed in 2001. cosmic rays also produce similar flashes of light, but can be distinguished based on the shape of the light flash. also having more than one telescope simultaneously observing the same spot can help exclude cosmic rays. extensive air showers of particles can be detected for gamma rays above 100 tev. water scintillation detectors or dense arrays of particle detectors can be used to detect these particle showers.

cosmic ray subsystem (crs, or cosmic ray system) is an instrument aboard the "voyager 1" and "voyager 2" spacecraft of the nasa voyager program, and it is an experiment to detect cosmic rays. the crs includes a high-energy telescope system (hets), low-energy telescope system (lets), and the electron telescope (tet). it is designed to detect energetic particles and some of the requirements were for the instrument to be reliable and to have enough charge resolution. it can also detect the energetic particles like protons from the galaxy or earth's sun. as of 2019, crs is one of the active remaining instruments on both voyager spacecraft, and it is described by as being able to detect electrons from 3–110 mev and cosmic ray nuclei 1–500 mev/n. all three systems used solid-state detectors. crs is one of the five fields and particle experiments on each spacecraft, and one of the goals is to gain a deeper understanding of the solar wind. other objects of study including electrons and nuclei from planetary magnetospheres and from outside the solar system.
