Stochastic acceleration of the beam of the 600-Mev synchrocyclotron was studied. The frequency program for the stochastic acceleration is described, and the acceleration mechanism is determined. Three-dimensional scattering and the constant of vertical scattering are analyzed. Beam loss near the center and in the region x, where r is much larger than h, is determined. The beam intensity is calculated, and methods to decrease the stochastic focalization are discussed. It is shown that a stochastic acceleration from a zero energy always causes a loss of particles because the focalization forces are too weak in the region where the energy is still very small. If the particles have attained an appreciable fraction of the final energy, the stochastic acceleration does not cause any loss of particles. It is possible to extract a beam from the accalerator in a stochastic method. An electrode placed at maximum enengy causes scattering of the beam on both sides of U/sub max/, that is, half the beam attains an energy highr than U/sub max/ and leaves the accelerator and the other half is decelerated and is lost.
