The TME (Theoretical Minimum Emittance) cell is being used now for designing the lattice of different storage rings (SR sources, damping rings, FFAG accelerators, etc.). Strong sextupoles required to correct the natural chromaticity of the lattice reduce the dynamic aperture. In the paper we consider the main features of the nonlinear perturbation strength and its connection with the essential lattice parameters: horizontal emittance, betatron tunes, and natural chromaticity. The analytical results are compared with the computer simulation.

A carbon ion or proton beams are a superior tool to x-rays in both physical and biological doses in treating a cancer. A carbon beam has an advantage in treating radiation resistant and deep-seated tumors. The main limitation of wide application is a high cost of facility. This problem can be solved by our proton and carbon ion accelerator facility proposal on the base of Cold Beam Synchrotron. The main feature of the facility is an application of electron cooling device. The ion beam is cooled down and the beam emittance and an energy spread are decreased. The final high quality cold ion beam with small transverse emittance and momentum spread allows to decrease significantly the aperture of the synchrotron and components of high energy beam transfer lines.

The rapid cycling booster synchrotron is used as pre-accelerator for carbon ion facility for cancer therapy. Booster provides about 1010 carbon ions per second at extraction energy 30 MeV/unit, at a repetition rate of 10 Hz. At the same time the booster can be used for acceleration of protons and delivers about 1012 protons per minute at a maximum extraction energy of 250 MeV in separate irradiation port.
