This paper explores the applied use of the RUSCOSMICS software package [http://ruscosmics.ru] designed to simulate propagation of primary cosmic ray (CR) particles through Earth’s atmosphere and collect information about characteristics of their secondary component. We report the results obtained for proton fluxes with energy distributions corresponding to the differential spectra of galactic CR (GCR) and solar CR (SCR) during ground level enhancement (GLE) events GLE65 and GLE67. We examine features of the geometry of Earth’s atmosphere, parametrization methods, and describe a primary particle generator. The typical energy spectra of electrons obtained both for GCR and for GLE65 provide information that allows us to quantitatively estimate the SCR contribution to the enhancement of secondary CR fluxes. We also present altitude dependences of ionization rate for GCR and both the GLE events for several geomagnetic cutoff rigidity values. The conclusion summarizes and discusses the prospects for future research.

Galactic Cosmic Ray

An oriented nuclear-emulsion detector capable of time resolution was exposed in Gemini Flight XI to investigate the primary cosmic-ray nuclei above the earth's atmosphere. This was the first satellite exposure of an emulsion apparatus designed to collect 103 high-quality tracks of heavy nuclei under a negligible thickness of matter (0.07 g/cm2). Time resolution was obtained by moving a lower stack, consisting of emulsions of various sensitivities, with respect to a shallower, sensitive upper stack at the rate of 25 microns/minute. It was thus possible to separate the "useful" tracks–formed during the oriented portion of the flight–from those formed at other times. Preliminary data are presented on the relative abundances of individual chemical elements in the high-energy cosmic radiation above the earth's atmosphere. These measurements are compared to published results obtained on balloon flights at similar latitudes. When sufficient data become available in a later phase of this experiment, particular attention will be directed towards the Be and B abundances, the N and F content relative to C and O, and the relative number of iron-group nuclei compared to the lighter ones.
