The celsius/WASA facility
The WASA (Wide Angle Shower Apparatus) is a new detector system with very high acceptance presently being commisioned at the CELSIUS storage ring located at The Svedberg Laboratory in Uppsala. It has been designed to study rare decays of light mesons with sensitivity down to 10-9 in the branching ratio. It will also allow for unprecedented quality measurements of differential cross sections of different reactions induced by protons and light nuclei.
