ISEE-C HKH High Energy Cosmic Rays

In this paper we describe a sateilite-borne multidetector cosmic ray telescope experiment. This package is designed to identify the charge and mass of incident cosmic ray nuclei from 11H to 6428Ni over the energy range from ~20 to ~500 MeV/nucleon. Particle identification is based on the multiple energy loss technique. The experiment will thus measure the isotopic abundances of the cosmic ray flux and provide essential information to help understand the origin of high energy cosmic rays.
