Primary cosmic ray absolute fluxes of proton and helium components are reported from RUssian Nippon JOint Balloon (RUNJOB) experiment. RUNJOB collaboration has been carrying out the balloon campaign since 1995. Total exposure so far becomes 342.4 m hour at the average altitude of around 30 km. Using the angular distribution of the secondary gamma rays and the darkness on X-ray films, the energy of the primary particle is estimated and the flux of proton components extends up to 1014 eV including an event with the primary energy of about 1 PeV. For helium, the flux up to 1014 eV/nucleon is obtained. The procedures of analysis and results of RUNJOB experiments are given here from campaigns in 1995 and 1996. This paper becomes a complete paper with next OG 1.2.15. Some explanations are found in next paper and vice versa.
The goals and status of the INCA Project are presented. New technique based on the ionization-neutron calorimeter (INCA) and designed to study the energy spectrum and composition of the primary cosmic radiation in the “knee” region as well as the spectrum of primary electrons in the range 0.1–10 TeV is discussed.
