ABSTRACT:
A method of producing a magnetron is disclosed which has a getter on at least one of the opposed surfaces of two end shields of a cathode. The getter is formed in such a manner that after the cathode is assembled, a paste containing a getter metal powder is coated on at least one of the opposed surfaces of the end shields and dried before the filament of the cathode is carburized and then while the magnetron is being exhausted, the dried paste is sintered to produce a sintered substance of the getter metal powder.
