    Abstract: A plasma source comprises a thermionic emitter (2) heated by an induction coil (7), which also provides radiofrequency energy within an electrically insulated cylindrical former (1). A cylindrical anode (10) is concentric with emitter (2) and axially displaced therefrom, generating a potential difference between anode (10) and emitter (2). The potential difference between anode (2) and ground and axial magnetic fields causes the plasma to be extracted from the source. Emitter (2) is held at negative potential via a conductive support (5). Process gas is introduced near emitter (2) and a secondary gas injected in the anode space. Radiofrequency excitation of emitter (2) generates electrons via thermionic and field effects, resulting in efficient plasma generation. Both electron generation effects contribute to a broad energy spectrum of electrons, providing effective neutralization of the plasma. Moreover, the time varying axial magnetic field induced by coil (7) in the vicinity of emitter (2) provides enhancement of plasma generation and confinement of plasma to minimize erosion of emitter (2).

    Abstract: Electrons are arranged so they circulate along a spiral path in a vacuum. The path has a hollow symmetrical shape which is defined by a surface of a toroid. The shape is controllable by a magnetic field and the electrons can be contained within the shape. A containing force can be created by external electromagnetic fields, ions within the vacuum, or by interactions between the orbiting electrons themselves. The contained electrons store energy for later retrieval.

    Abstract: A low-pressure mercury vapor discharge lamp with a discharge vessel (10) having first and second end portions (11). The discharge vessel encloses a discharge space provided with a filling of mercury and an inert gas in a gastight manner. Each end portion (11) supports an electrode (20) which is arranged in the discharge space and secured to current supply conductors (30A, 30B) which are passed through the end portion (11) so as to project outside the discharge vessel (10). A segment (31A) of at least one current supply conductor (30A), which extends between the end portion (11) and the electrode (20), is covered with an amalgam. The region (35A) is situated at a distance da from the end portion (11). The amalgam can be relatively easily applied in the discharge lamp according to the invention.
