Abstract

The article considers a proton accelerator containing seven independent beams arranged on the accelerator radius. The current in each beam is one hundred milliamps. The initial part of the accelerator consists of shielded spiral waveguides assembled in the common screen. The frequency of the acceleration: three hundred megahertz, high-frequency power twenty-five megawatts, the length of the accelerator six meters. After reaching the proton energy of six megaelektronvolts the protons using lenses with the azimuthal magnetic field are collected in one beam. Further beam acceleration is performed in the array of superconducting cavities tuned to the frequency one and three tenths gigahertz. The acceleration rate is equal to twenty megavolt per meter, the high-frequency power consumption fifteen megawatts per meter.
