Charmonium physics is uniquely possible in a tau charm factory. The expected increase in data samples is a factor 100-1000 over current experiments. The physics potential and opportunities are (1) In gluonium physics, search for a bound state of 2 or more gluons by careful spin parity analysis of states produced in radiative J/{Psi} decays. (2) In {Psi}{prime} decays, there are many charmonium measurements which currently are either poorly measured or non-existent. These include the two and three photon width of the {eta}{sub C} and J/{Psi}, the discovery of the {eta}{prime}{sub c}, the measurement of the hadronic decays of the {chi}{sub c} and the normalization of the p{bar p} decays of the charmonium states observed by E760. (3) Further progress in understanding the hadronic {Psi}{prime} decays require a large statistics sample to measure the pattern of hadronic decays. A careful comparison to the J/{Psi} hadronic decays should clarify this puzzle. The ultra high rate of the J/{Psi} decays permits the possibility of high statistics study of light quark mesons. It appears a tau charm factory could contribute many branching ratio measurements. Finally, the ultra high rates of the J/{Psi} and {Psi}{prime} decays permits a careful study of the detector acceptances which will be necessary to make further progress in tau and charm physics.
