Apparatus for generating a uniform magnetic field in a cylindrical oriented post cathode. The vacuum chamber has a cylindrical wall of non-magnetic material and end walls of magnetic material. An array of bars of magnetic material is disposed to surround the vacuum chamber and to form a magnetic circuit including the end walls of the chamber and a region extending through and adjacent to the post cathode. Solenoid windings are positioned between the cylindrical wall of the chamber and the bars of magnetic material.
