Isotopic analysis of cosmic rays by the Cerenkov-Cerenkov slowing-down method
Abstract
The performance of a large-scale Cerenkov-Cerenkov slowing-down set-up for isotope analysis in the 1-2 GeV/n region is analysed. Such a setup should permit isotopic analysis of all nuclei between neon and nickel with rms mass errors less than 0.5 amu and less than 1 amu over, respectively, approximately 250 MeV/n and approximately 500 MeV/n energy ranges. The background associated with the very high rate of nuclear interactions in the instrument (75 percent) should be eliminated by a triple redundancy in the charge measurement. These estimates are based largely on experience gained from Danish-French balloon flights and from runs at the Berkeley Bevatron.
