One of the main advantages of proposed by P. Raimondi "Crab Waist" collision scheme is a strong suppression of betatron resonances excited by beam-beam interaction. Some qualitative explanations with numerical examples, describing beam-beam resonances for different collision schemes, were given in [2]. This paper can be considered as an "appendix" (additional illustration) to that one. We performed a number of full 2D betatron tune scans (beam-beam simulations) for different collision schemes, so one can easily see how the beam-beam resonances appear and disappear, depending on the colliding conditions.

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.
