Magnetron injection guns derived from theorectical space-charge flow solutions

  • N. J. Taylor


During the past three years we have had occasion to design and build magnetron-injection guns for producing hollow beams. These guns have been designed both from a planar space-charge flow which has been described by Kino and Taylor [1] and more recently from one of the axially-symmetric flows described by Kirstein [2]. Though these flows may be a gross simplification of what might actually occur in a crossed-field gun of this type wehave found that they enbale us to predict perveance and cathode current-density distribution to a most useful degree of accuracy.
