    摘要: A spectral source comprises a lamp containing an anode and a cathode in an inert gas. The anode and cathode are different in shape and connected to a high-frequency power source to produce a high-frequency discharge between the anode and cathode to cause both sputtering of the cathode and excitation of a radiation having the spectrum according to the material sputtered from the cathode. The application of solely high-frequency power prevents adherence of the sputtered material to the interior walls of the lamp bulb thereby allowing a reduction of the dimensions of the lamp bulb, prolongating the life time of the lamp and increasing the stability and intensity of the radiation. A magnetic field may be applied to the radiation for Zeeman modulation. Due to the relatively small dimensions of the lamp bulb, relatively small and inexpensive magnets may be used.

    摘要: A spectral source comprises a lamp containing an anode and a cathode in an inert gas. The cathode has a hollow portion therein, and a opening at its side wall. The anode is positioned to face the opening of the cathode. The anode and cathode are different in shape and connected to a high-frequency discharge power source. A magnetic field is arranged in perpendicular to the direction of the axial center of the opening.
