Method of producing radiofrequency resonating cavities of the weldless type

摘要

A method of producing weldless resonating monolithic cavity comprising the steps of: arranging a die which can be disassembled into sectors and having the form of the internal cavity of the resonator; spinning a foil by using said die so as to provide a monolithic weldless body of metal sheet which coats exactly and completely the die; and disassembling and removing the sectors of the die through one opening of the resonator.
