The range of magnetron injection gun parameters

Here, for the first time, the computer designs of axially symmetric magnetron injection guns are given in detail, and the practical problems of computing the electrodes are discussed. These designs have been experimentally used, showing that the design procedure is sufficiently accurate for predicting the characteristics. The important design parameters such as perveance, area convergence and magnetic field required are given for the interesting range of the normalized "computer" parameters. A method is suggested for computation of the resulting hollow beam from a truncated cone cathode, and the design of a transition region is discussed.
