The magnetic field of the proton syncharotron at the Joint Institute for Nuclear Research is characterized by the following parameters: peak magnetic field intensity at the equilibrium orbit (R = 2800 cm), H/sub max/ = 13,000 gauss; field intensity at injection, H/sub o/ = 150 gauss; gap height between the poles at the equilibrium orbit, delta = 40 cm; and width of the pole piece, b = 200 cm. Because of the need for meeting extremely severe magnetic tolerances, it was necessary to work out effective methods for correction of the magnetic field before the accelerator was built. A small model was built for preliminary investigation of the magnetic characteristics; the final study of the magnetic charaeteristics and the development of methods for correcting the magnetic field were performed on segments, each segment being 1/48 of the circular magnet. The methods used in deriving the static and dynamic characteristics are given in detail. The magetic characteristics obtained in studies of the individual segments and the methods of field correction developed were completely verified during the tents and adjustments of the assemabled electromagnet. (J.S.R.) The most important feature of the high-energy electron synchrotron is the intense electromagnetic radation due to the relativistic motion of the electrons in the magnetic field of the accelerator. It is shown that the electron motion may be considered classical up to the maximum possible energies. However, account must be taken of the statistical nature of the quantum fluctuations of the radiation itself in treating the electron motion. The motion of an electron in an accelerator with an axially symmetric magnetic field with radiation present is considered, and the equations for the change of amplitude of the betatron and synchrotron oscillations are derived within the framework of the classical theory starting with the relativistic equation for the motion for a point electron. The effect of radation fluctuations on electron motion in an accelerator with an axially symmetric field is next considered, and the equation for the amplitude of the z oscillations is given. Betatron oscillations in periodic magnetic systems in the presence of radiation and the damped-oscillation method are discussed. Several methods of overcoming radiation blow-up'' are suggested. The effect radiation fluctuations on betatron and synchrotron oscillations in periodic magnetic systems is analyzed. To compete the description of the electron motion in accelerators, the effect of the discrete action of the accelerating gaps is considered. (J.S.R.)
