A Giant Air Shower Array in Nord Rhein Westfalen

Abstract

A proposal is presented to construct a very large air shower array in the densely populated central area of Nord-Rhein-Westfalen (NRW). The aim would be to reach a size of approximately 4000 km${}^2$ to study the highest energy end of the all particle cosmic ray spectrum, as it is accessible in the northern hemisphere.
