Reconstruction of charge number of heavy cosmic rays using Cherenkov Light — •Robert Stein, Attila Abramowski, and Dieter Horns — Universität Hamburg, Hamburg, Germany

Between impact with the upper atmosphere and decay into a charged particle shower, heavy cosmic ray elements such as Iron emit Cherenkov Light at an angle determined by the Refractive Index of the air and the energy per nucleon. This direct Cherenkov Light forms a characteristic circular light distribution on the Earth's surface with an intensity proportional to the square of the cosmic ray charge. A new method has been developed to reconstruct this charge number. The expected performance for various existing and planned installations will be presented.
