Sažetak
The SLAC Crystal Ball (CB) detector was recently installed on the C6 beamline at the AGS. A two week engineering run and a two week data run looking at all neutral final states from pi^p interactions were completed in the spring of 1997. This marks the beginning of a new diverse program in baryon spectroscopy at BNL. Some of its goals are to improve the determination of the masses, widths and decay modes of baryon resonances in the region E_cm below 2150 MeV/c, to search for possible exotic states such as pentaquarks and hybrids, to determine meson-nucleon scattering lengths such as eta-n, eta-Lambda, and eta-Sigma for example, and to measure inverse photoproduction of K^- mesons from the unstable Lambda and Sigma hyperons. A description of the experimental setup and performance of the detector is given along with some preliminary results from the data run.
