AbstractDuring the World War II theory of the magnetron was developed by S. Tomonaga in collaboration with M. Kotani. Assuming a parabolic potential between the cathode and the cylindrical anode of the magnetron, he calculated the electron orbits perturbed by the oscillating field of the anode. Secular change of the electron orbit results in the formation of rotating space charge inside the split-anode magnetron, which is found to enhance the oscillating field when a resonance condition is satisfied.
