Abstract: A high performance hollow cathode lamp comprises an common anode and an open-ended hollow cylinder as primary cathode consisting of a selected element adapted to produce a primary electric discharge, which give rise to an atomic vapor of said element by cathode sputtering from the primary cathode, between the anode and the primary cathode. An auxiliary cathode in form of hollow cylinder with one or two open ends is provided to produce a secondary electric discharge. A shielding tube covering the anode and the primary cathode serves to constrain the electron stream of the secondary discharge extending from the auxiliary cathode to the common anode to pass through the primary cathode to excite further the atoms in the vapor to emit radiation characteristic of said element.
