Abstract
Electron-positron collider Super Charm Tau factory is
planned to be built in the National center for physics and
mathematics, Sarov. It is a double ring collider with crab waist
collision scheme operating in wide beam energy range from 1.5 GeV
to 3.5 GeV with peak luminosity of 1035 cm-2s-1. The polarized electron
source and three Siberian Snakes provide 80% longitudinally
polarized electron beam at 2 GeV. Superconducting wigglers
decrease damping times, effects of intra-beam scattering and
increase Touschek beam lifetime, particularly at low energy. The
paper presents the status of collider design and optimization of
luminosity and beam lifetime.
