Abstract
The COSY-II installation is an internal experiment at the cooler synch rotron and storage ring COSY Julich. It has been designed for full geo metrical acceptance close to threshold for meson production studies, e specially in the 1 GeV/c(2) mass range. The experimental setup makes u se of a regular C-type COSY dipole magnet, following a cluster target, to separate reaction products from the beam and to analyze their mome nta, thus allowing the observation of charged reaction products at sma ll angles with beam energies close to threshold. Resonances will be id entified by missing mass reconstructions from measured four-momenta of two outgoing protons in the predominantly studied pp-->ppX reaction. In addition, charged mesons either produced directly or from decays of X will be detected. The different components of the experimental faci lity are presented.
