Magnetron construction particularly useful as a relativistic magnetron

摘要

A magnetron includes a cathode and an anode in a vacuum chamber radially spaced from each other to define an interaction region in which a magnetic field is produced parallel to the interaction region. The anode is supplied with positive high-voltage pulses while the cathode and vacuum chamber are at a reference (ground) potential. The anode is of annular configuration located coaxially around the cathode and is formed with cavities facing the cathode, in the form of a rod, and is formed with cavities facing the cathode to define an annular interaction region between the anode and cathode.
