Abstract:
An apparatus for producing a stream of atomic particles in the form of free atoms or radicals, said apparatus comprising:an elongated heat-conductive and thermally conductive tube formed at one end with means for connecting said tube to a source of a gas capable of being thermally decomposed to form said atomic particles, said tube being formed at an opposite end with an outlet for said stream of atomic particles;at least one heating wire extending along said tube and spaced from said tube over at least a major portion of a length of said wire whereby said tube is radiantly heated by said wire to a temperature sufficient to thermally decompose said gas and form said atomic particles, said wire having an electrical contact with said tube at a location proximal to said outlet and being spaced from said tube over a remainder of a length of said wire juxtaposed with said tube; andan electrical energy source connected to said wire for passing an electric current therethrough to cause said wire to radiantly heat said tube.
