Status report on WASA at COSY

The installation of the WASA detector setup at COSY has been accomplished during summer 2006, and the facility is now on track to start its physics program beginning of 2007 as originally scheduled. Various improvements to the original detector setup have been carried out, among them a complete renewal of the data acquisition system. Together with the extended capabilities of COSY this will allow for high statistics measurements of η and η' decays and dedicated production experiments in isospin filtering reactions, providing suitable tools to investigate fundamental symmetries and symmetry breaking patterns in hadronic systems. After the successful detector commissioning end of 2006, we are now looking forward to a first production run in April 2007, aiming for a precision determination of the Dalitzplot slope parameter for the isospin breaking η → 3π decay, where recent experimental results from KLOE and Crystal ball differ beyond the quoted errors. The feasibility of such a measurement using the WARA detector setup could already be demonstrated during the operation of WASA at CELSIUS. We report on the present status of the facility and give an outlook on the proposed physics program. (orig.)
