Abstract
The basic data on a cyclotron with a pole-piece diameter of 120 cm are given. The arrangement of the principal parts of the system, the design features of the individual units, the radio frequency (rf) installation, the method of measuring and correcting the magnetic field, the features of the deflection system, and the method of focusing the beam on a remote target are all described. Deuterons are accelerated to an energy of 13.7 Mev in this machine. The use of a deflection system with focusing properties makes it possible to use magnetic quadruple lenses with small apertures which bring practically the entire deflected beam to a remote target. The parameters of the machine are such, that it will be possible to increase significantly theenergyof the accelerated ions in the future.
