Construction of a magnetron be used in particular as a magnetron relativistic.

摘要

A magnetron includes a cathode (25) and an anode in a vacuum chamber (21) which is radially spaced apart from one another in order to define a region of interaction (28) in which a magnetic field is produced in a direction parallel to the region of interaction. The anode is applied to the positive high voltage pulses, whereas the cathode and that the vacuum chamber are at a reference potential (ground). The anode is an annular configuration positioned coaxially around the cathode, and it is provided with cavities (27) facing the cathode in order to define an annular region of interaction between the anode and cathode.
