Abstract
We describe the detecting system of a high-energy charged particle telescope spectrometer for a space experiment to be performed on the outer surface of the Russian section of the International Space Station and other spacecraft, including small satellites. The spectrometer’s detecting system is a multilayer scintillation detector (MSD) of polystyrene plates scanned by photomultipliers. It allows high-intensity fluxes of electrons (up to ∼105 cm−2 s−1) several milliseconds long with energies of 3 to 30 MeV to be measured with an accuracy of ∼1 μs, along with time profiles and the evolution of particle energy spectra. The MSD is characterized by an energy resolution no worse than 10%, an angular resolution of ∼10 degrees, a geometric factor of ∼40 cm2 sr, and a trigger system time resolution of ∼20 ns.
