Abstract:
This disclosure provides a device for heating a cathode of a magnetron, which includes a heater for heating the cathode of the magnetron, a heater current detecting module for detecting a value of heater current that flows into the heater, and a control module for determining the completion of preheating of the magnetron based on a change in the heater current.
