  • Hollow anode optical radiation source
    Patent number: 4906890
    Abstract: In a discharge tube for use in a housing for a vacuum, an improved optical radiation source is formed by a cathode and a hollow anode. The hollow anode has at least one first surface defining a hollow, partly closed space. The first surface is disposed for cooperation with the cathode. The hollow anode also has at least one second surface that also could cooperate with the cathode. Only the first of the first and second surfaces is conductive. Electrodes are respectively connected to the cathode and hollow anode.

  • Hollow-anode ion-electron source
    Patent number: 4871918
    Abstract: An ion-electron source based on a new type of gas discharge in a hollow anode is presented. A small surface of the exit aperture and a high density of the current enable high brightness of the source; high efficiency and simple construction make possible low production price and long lifetime of the source.
