Simulating a cyclic electron path in a magnetron
Magnetrons are typically used in microwave ovens and certain radar applications. The inside conductor is the cathode and the cylindrical shell on the outside is the anode. A coil is wrapped around the tube so that a magnetic field that is parallel to the axis of the tube is produced. The electric and magnetic fields are perpendicular to each other.
Electrons move from the cathode to the anode, they are forced to travel on a path that is bent due to the magnetic field.
The trajectory of an electron in a magnetron can be simulated based on the fields present in the space between the cathode and the anode.
Using Simcenter MAGNET, Simcenter MAGNET Electric and the Trajectory Evaluator, the electric and magnetic field strengths are adjusted so that the path of the electron does not reach the anode and forms a cyclic trajectory.Open Report (Model 0095)
