In the observed cosmic ray primary spectrum, the ratio of particles attributable to source, to those generated by spallation in the interstellar medium, increases progressively with energy. An experiment to investigate this phenomenon is proposed which simultaneously measures gas scintillation (dE/dx) and Cerenkov radiation from a solid detector for all particles, and Cerenkov radiation from a series of gas detectors, to determine the energy of the higher energy components. The salient feature of the experiment is the combination of gas scintillator/solid Cerenkov signals, essentially providing high charge resolution from Z approximately 6 to Z 92, together with the gas Cerenkov detectors, which allows making reliable energy determinations up to 600 GeV/n for Fe nuclei. The near spherical geometry proposed allows the experiment to have the high aperture factor so necessary for these low flux particles.
