method and device for the deposition of thin films by cathodic spruzzamento superconducting niobium cavities with muffled on to quarter wave in copper for the acceleration of heavy ions.

摘要

method for the production of a thin film coating the inside of cavity with muffled to quarter wave in copperconsisting of the deposition spruzzamento cathode (sputtering) diode polarised in continuous current of a superconducting material, in particular niobium.in the form of micro layer to a thickness that is practically constant and the cylindrical surface of the cavity, and the flat plate which forms the bottom of the same.by having a form that follows cathodes emitters geometrically the management of the land to play.
