In August 2006 experiments with the WASA-at-COSY detector began at the Institute for Nuclear Physics, Research Center Jülich. A combination of a high quality particle beams in the Cooler Synchrotron and almost 4π-acceptance by the WASA detector system for charged and neutral particles provide unique opportunities to extend studies of symmetries and their violation, e.g. isospin breaking. In the WASA-at-COSY experiments with a unique pellet target system and intensive particle beams the rare decays of η and η′ mesons can be measured with high statistics. To cope with the higher beam energy available in COSY the WASA detector has been upgraded. To improve the resolution of the particle kinetic energy measurements and to provide particle identification capabilities a Cherenkov detector has been proposed. Evaluation of the amplitude analysis Cherenkov detector concept for the WASA-at-COSY collaboration is presented.
