20000065646 Joint Inst. for Nuclear Research, Frank Lab. of Neutron Physics, Dubna, USSR Cosmic rays - possible generator of electrostatic field in earth atmosphere Matora, I. M.; Semenova, I. A.; Shakun, N. G.; Shishlyannikov, P.; Dec. 31, 1998; 11p; In Russian; In English Report No.(s): DE99-607983; JINR-R-1-98-68; No Copyright; Avail: Department of Energy Information Bridge Closeness to the 1 probability of an inversion of the total electric current, generated by the primary relativistic protons and other hadrons of cosmic rays (CR), from positive at the entrance into the atmosphere to negative at the earth surface is shown. The inversion appears as a result of the fact that the penetration ability of the shower electrons, the direction of the velocities of which is close to that of the primary CR flow, exceeds the paths of the secondary positive ions by more than one order of magnitude.

The method is based on measuring of Cherenkov light distribution in showers. A new approximation of the lateral and radial distributions is obtained on the basis of a nonlinear overdetermined inverse problem solution. The concrete mathematical model is created by analysis of recent measurements carried out by the Cherenkov wide angle timing telescope HOTOVO. The model is tested on simulated data obtained with the code CORSIKA. The method is applied to different sets of detectors of CELESTE array. A new detector array for optimal estimation of Cherenkov flux parameters is proposed. NTIS Meteorological Parameters; Cosmic Ray Showers 234
