A low budget detector for high energy cosmic ray experiments

Contemporary projects such as AUGER in Argentina or HESS in Namibia are rather expensive experiments. We have constructed a simple detector arrangement based on the water Cherenkov technique to be used for the detection of high-energy particles in cosmic ray experiments either as stand-alone experiment or as addition to other set-ups. A first prototype has been taken into successful operation. The construction of this detector is the starting point for extended studies in future cosmic ray experiments. The detector can be expanded by adding more and more modules at a very low price.
