The CW high-current proton linac with superconducting devices for electronuclear purposes

The concepts in designing of the two types of high-current proton linacs having the electronuclear purpose with the output energy about 1GeV and currents 200-300mA (the first type) and 10mA (the second type) are developed. The major problems arising in both cases is ensuring high reliability and efficiency of linacs. For the first type the high reliability is mainly connected with solving of the problem of minimizing the particles losses down to the level of 10-5 and of building the reliable super high-power RF power supply system. For the second type the problem of increasing the efficiency is of major importance. In the report the ways to solving of these problems by means of using the superconducting solenoidal focusing together with the optimized RF power supply system (for the first linac type) and the superconducting accelerating cavities (for the second type) are shown
