Abstract

A method for improving service life of a magnetron, which belongs to the technical field of microwave applications, includes: taking anode working voltage range is taken as n voltage values U1 . . . Un constituting an arithmetic sequence; taking the voltage value as the anode voltage; in each voltage value, adjusting the magnet coil current between I min and Imax by the coil current control part , so that the output power P of the experimental magnetron is equal to the target power P0, and measuring the cathode filament temperature at this time by the temperature measuring part, which is denoted as Ti; measuring all the cathode filament temperatures Ti as the temperature data set corresponding to P0 by the temperature measuring part; taking out the minimum temperature value Tmin in the temperature data set, and using the anode voltage value and the magnet coil current value corresponding to Tmin as the working magnetron, wherein the output power is the anode voltage value and the magnet coil current value of P0. The present invention provides a method for improving the service life of a magnetron, which adjusts the electric field and the magnetic field, finds the synergy between the magnetic field and the electric field, and improves the service life of the magnetron.
