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.

Method of producing radiofrequency resonating cavities of the weldless

A method of providing a thin film for lining quarter-wave resonant cavities of copper comprises the deposition of a superconducting material, in particular niobium, in the form of a micro-layer having a substantially constant thickness covering both the cylindrical surface of the cavity and its bottom formed of a plane plate, by biased-diode d.c. sputtering through emitting cathodes in a form fitting geometrically the surfaces to be lined.
