	Now the cyclotron seems as the most suitable accelerator for production of proton beams with energy up to Ep= 800 MeV and the power Pp=10 MW. There are some offers on creation of such complexes, all of them have common properties. A full cycle of acceleration consists of three stages: high-voltage injection with bunching of continuous beam, then preliminary acceleration in fore sectors cyclotron and acceleration up to the maximal energy 500-800 MeV in the ring cyclotron with six or more sectors. At the first stage of acceleration instead of high-voltage injection one can use the parallel work of two cyclotrons with injection in the subsequent cascade of a beam of the double intensity. In our department of New Accelerators the magnetic and high-frequency systems of a ring cyclotron on the energy 50 - 800 MeV (so-called “supercyclotron”) have been developed. A project of cyclotron injector with energy of protons about 10 MeV has been suggested as injector for Fasotron JINR LNP. It is offered to continue development of the project of cyclotron facility with energy of protons Ер ~ 800 MeV and average current of beam up to 10 mA.
