Abstract
The latest developments in the spectroscopy of charmonium physics are discussed. For the charmonium experiments, a cluster jet target of hydrogen intersects the circulating beam in the accumulator ring, and the electromagnetic products of annihilation, photons and electrons, are detected in an azimuthally symmetric detector located around the intersection region. Charmonium resonances are scanned by varying the antiproton energy in small steps, and unprecedented mass resolution are realised. At GSI, Darmstadt, an ambitious program of charmonium physics is being developed based on a 50 GeV proton synchroton and a 15 GeV/c antiproton storage ring.
