The physics opportunities in e/sup /plus//e/sup /minus// collisions with /radical/s /approx equal/ 1-2 GeV and e/sup /minus//e/sup /minus// collisions with /radical/s /approximately/5 GeV at Tau-Charm Factory are being explored. The low-energy e/sup /plus//e/sup /minus// option allows precise measurements of e/sup /plus//e/sup /minus// cross sections into /pi/'s and /eta/'s and hence stringent tests of the conserved-vector-current (CVC) hypothesis in /tau/ decays. Precise measurement of the total hadronic cross section also permits a more precise calculation of the muon anomalous magnetic moment (g-2). The e/sup /minus//e/sup /minus// option provides an opportunity for a sensitive search for lepton-number violating processes e/sup /minus//e/sup /minus// /yields/ /mu//sup /minus///mu//sup /minus//, /tau//sup /minus///tau//sup /minus//, /mu//sup /minus///tau//sup /minus// .... The e/sup /minus//e/sup /minus// collider also provides an ideal laboratory for two-photon physics with no one-photon background and the direct measurement of the two-photon background in one-photon physics 19 refs., 4 figs.
