Design of a High Luminosity Collider for the Tau-charm Factory*
نویسنده
چکیده
Important relations between basic parameters of a high-luminosity collider are discussed. As the result, it is shown that the maximum bunch spacing is limited by the beam current to clear the threshold of the bunch lengthening. In order to solve the short bunch spacing, the crab-crossing scheme is applied to a design of the ring with 2.2 GeV, 2 x 1O33 cm-2s-1 luminosity. *Work supported by Department of Energy contract DE-AC03-76SF00515. *Permanent address: KEK, National Laboratory for High Energy Physics, Oho, Tsukuba, Ibaraki 305, Japan.

The current plans for a high luminosity e+ecollider operated between 3.0 and 4.4 GeV/c2 are described. Such a dedicated facility (The Tau-Charm Factory), operating near tau-pair and charm thresholds would allow studies of the decay of the third generation tau-lepton and the second generation c-quark with unprecedented precision and control of systematics. The charm physics of such a facility is...

The type of high luminosity, storage ring collider being studied by SLAC for a tau-charm factory will require high energy, low emittance sources of positrons and electrons suitable for filling the rings. Ideally, the fill time should be much shorter than the luminosity life-time of the rings. For the purpose of estimating the characteristics of the injection system, the maximum fill time is tak...
