	The project of a new-generation t-charm factory is now under consideration in Novosibirsk. A novel approach of the Crab Waist collision scheme allows reaching the luminosity of 1-2*10e35 cm-2s-1. The other features of the facility are: variable energy from 2 GeV to 4.5 GeV (c.m.), longitudinal polarization of electrons at IP, usage of damping wigglers to keep high luminosity for all energy levels, etc. We discuss some of the challenges and opportunities available with the development of the project.

WEACH10	IR Design for Super-ct-Factory	82
	A.Bogomyagkov Budker INP, Novosibirsk
	Interaction region of Super-ct-factory is designed to bring stored electron-positron beams into collision with luminosity of 10e35 cm-2sec-1. In order to achieve that CRAB waist collision scheme is implemented, which requires cross angle collision with high Piwinski angle. The small values of the beta functions at the interaction point and distant final focus lenses are the reasons for high nonlinear chromaticity which limits energy acceptance of the whole ring. The present design is based on chromatic properties of telescopic transformation, on local chromaticity correction schemes and on as close as possible placement of CRAB sextupole.
