Abstract
We present the detection system of high-energy charged particle telescope-spectrometer for space experiment, which is scheduled to take place on the outside the Russian segment of The International Space Station (ISS) and other spacecrafts and small satellites. One of the scientific objectives of experiment is to study electron beams propagation in the magnetosphere. Such a beam can form in acceleration electrons by high-altitude electrical discharge and are injected in the magnetosphere. The detection system for this experiment is developed on the basis of the multilayer scintillation detector (MSD). The MSD is made by polystyrene plates viewed photomultipliers. It can detect 3-30 MeV intense electron beams (up to∼105 cm−2s−1) of up several milliseconds, can measure time profiles with accuracy ∼ 1 microsecond and energy spectra of particles evolution. MSD's main parameters: geometric factor ∼40 cm2·sr, trigger system time resolution ∼20 ns, energy resolution 5-10%, angular resolution ∼ 10 grad.
