Some problems and perspectives in cosmic-ray studies

The principles of an ionisation calorimeter, an instrument used to measure the energy of cosmic-ray particles and the dependence of its parameters on the conditions of operation, are discussed.Possible applications of this calorimeter in the study of nuclear interactions of 10¹¹–10¹³ eV cosmic-ray particles, study of the composition of high-energy primary cosmic rays (10¹¹–10¹⁴eV), and investigation of the electron component of cosmic-ray primaries and high-energy -rays are reviewed.Translated by Express Translation Service, Wimbledon, London.
