Universality of electron distributions in high-energy air showers - description of Cherenkov light production
نویسندگان
چکیده
The shower simulation code CORSIKA has been used to investigate the electron energy and angular distributions in high-energy showers. Based on the universality of both distributions, we develop an analytical description of Cherenkov light emission in extensive air showers, which provides the total number and angular distribution of photons. The parameterisation can be used e.g. to calculate the contribution of direct and scattered Cherenkov light to shower profiles measured with the air fluorescence technique.

متن کاملA study on the lateral distribution of Cherenkov light in extensive air showers
The dependence of the lateral distribution of Cherenkov light in simulated extensive air showers to the energy and the mass of the primary cosmic rays has been studied. It has been shown that a previous claim about mass independent proportionality of shower energy to the total Cherenkov photon number is not valid in energies below EEAS ~ 1014 eV. We have found that the core distance of the so c...
متن کاملUniversality of electron-positron distributions in extensive air showers
p a Using a large set of simulated extensive air showers, we investigate universality features of electron and positron distributions in very-highenergy cosmic-ray air showers. Most particle distributions depend only on the depth of the shower maximum and the number of particles in • the cascade at this depth. We provide multi-dimensional parameterizations for the electron-positron distribution...

متن کاملReconstruction of Longitudinal Profiles of Ultra-High Energy Cosmic Ray Showers fromFluorescence andCherenkov LightMeasurements
We present a new method for the reconstruction of the longitudinal profile of extensive air showers induced by ultra-high energy cosmic rays. In contrast to the typically considered shower size profile, this method employs directly the ionization energy deposit of the shower particles in the atmosphere. Due to universality of the energy spectra of electrons and positrons, both fluorescence and ...
