A new method for determining particle energy in the range 1011−1015 eV and results from a beam test at 180 GeV/c
A method for measuring the energy of the nuclear component of cosmic rays is described. The principle of the method consists in determining the energy of a primary nucleus from the space density of secondary particles produced in a thin target in the initial event of inelastic interaction. The results from testing the method on an ejected 180-GeV pion beam are presented. Analysis of the experimental data and simulation show that, using this method, it is possible to measure the particle energy with a relative error of ∼67%. The method is being developed for the direct detection of cosmic rays over wide ranges of energy (1011−1015 eV/particle) and charge (Z = 1–30) during a cosmic experiment in near-Earth space.
