摘要：
We present a new design for the water Cherenkov detectors that are in use in various cosmic ray observatories. This novel design can provide a significant improvement in the independent measurement of the muonic and electromagnetic component of extensive air showers. From such multi-component data an event by event classification of the primary cosmic ray mass becomes possible. According to popular hadronic interaction models, such as EPOS-LHC or QGSjetll-04, the discriminating power. between iron and hydrogen primaries reaches Fisher values of similar to 2 or above for energies in excess of 10(19) eV with a detector array layout similar to that of the Pierre Auger Observatory.
