Abstract

1,020,224. Discharge lamps. HITACHI SEISAKUSHO KABUSHIKI KAISHA. Jan. 22, 1963 [Jan. 22, 1962], No. 2763/63. Heading H1D. An electron cyclotron resonance lamp for producing U.V. radiation of 2,000 Š or less comprises means (e.g. electrodes 2, 3) for creating a plasma (e.g. glow discharge in a gas at 1 Á) existing in a magnetic field (e.g. from coils 6 and 7) and means (e.g. waveguide 9) for supplying electromagnetic radiation at such a frequency that resonance absorption by the electrons in the plasma occurs, raising the kinetic energy of the electrons to the equivalent of 2À10<SP>4‹</SP>K. These electrons, upon collisions with gas molecules in the plasma, then cause hard U.V. emission. The electromagnetic field may be perpendicular or parallel to the magnetic field, and the resonance absorption may be obtained by varying the gas pressure, the magnetic field, or the frequency of the electromagnetic radiation.
