CARBON ION ACCELERATOR FACILITY FOR CANCER THERAPY

A carbon ion or proton beams are a superior tool to x- rays in both physical and biological doses in treating a cancer. The 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 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.
