Abstract:
A method and apparatus for stabilizing glow plasma discharges by suppressing the transition from glow-to-arc includes a perforated dielectric plate having an upper surface and a lower surface and a plurality of holes extending therethrough. The perforated dielectric plate is positioned over the cathode. Each of the holes acts as a separate active current limiting micro-channel that prevents the overall current density from increasing above the threshold for the glow-to-arc transition. This allows for a stable glow discharge to be maintained for a wide range of operating pressures (up to atmospheric pressures) and in a wide range of electric fields include DC and RF fields of varying strength.

Each of the micro hollows has dimensions selected to produce a micro hollow discharge at the prescribed pressure. Preferably, each of the micro hollows has a cross-sectional dimension that is on the order of the mean free path of electrons in the gas. Electrical energy is coupled to the cathode and the anode at a voltage and current for producing micro hollow discharges in each of the micro hollows in the cathode. The discharge device may include a discharge chamber for maintaining the prescribed pressure. A dielectric layer may be disposed on the cathode when the spacing between the cathode and the anode is greater than about the mean free path of electrons in the gas. Applications of the discharge device include fluorescent lamps, excimer lamps, flat fluorescent light sources, miniature gas lasers, electron sources and ion sources.
Abstract:
A display apparatus includes a pair of substrates connected to each other via a pre-set gap for delimiting a hermetically sealed space, an ionizable gas charged into this space, and discharging electrodes formed at least on one of the substrates to incur discharge in the space. The discharging electrodes are coated with a protective skin film formed by the electro-deposition method. The protective skin film is an electro-deposited and sintered mixture of boride or carbon containing electrically conductive powders and glass powders. In electro-deposition, the mean particle size of the electrically conductive powders and the glass powders is not larger than 10 nullm or in a range from 1 to 3 nullm. The electrically conductive powders and the glass powders are mixed in a volumetric ratio in a range from 9:1 to 3:7, with the film thickness of the protective skin film being in a range from 1 to 20 nullm. This enables suppression of deterioration of the discharging electrodes with lapse of time, while enabling the lowering of the discharge voltage.

Abstract:
Apparatus for forming an electron beam sheet includes a cathode member having a slot in a front surface thereof, a grid electrode and the anode of a thyratron. When it is desired to trigger the thyratron into conduction, a suitably large potential difference is applied between the cathode member and the grid, resulting in an electron beam sheet being produced extensive of a slot formed in the front surface of the cathode member. This produces ionisation and a main discharge current is established between the main anode and cathode of the thyratron.
