On the problem of a cyclotron for particles with relativistic increase in mass

The paper deals with the problem of circular accelerators with time constant magnetic field and constant frequency of the accelerating voltage. An analysis is made of the possibility of compensating the change in time of revolution (caused by the increase in mass during energy growth) by simultaneous axial and radial displacement of the equilibrium orbit. It is found that the problem can be solved only with certain approximations. The approximate numerical parameters of the accelerator are given and the approximations used are discussed. The paper is based on 1].
