摘要： A switch has a gas discharge chamber in which two electrodes, namely a cathode (11) and an anode (12), are arranged at a distance (d) apart and are separated from each other by an electrically insulating wall (9a) of ceramic material or glass. The cathode (1) has a hole (5) and the electrodes (11, 12) are connected to the insulating wall (9a) through a dense metal-ceramic compound or fused material. The gas discharge chamber contains an ionizing low pressure gas under a pressure p such that ignition of a gas discharge occurs between the electrodes (11, 12) at a voltage on the left, descending branch of the Paschen curve. For at least one of the two electrodes (11, 12), the connecting lines (4) at which the respective electrodes (11, 12), the gas and the wall (9a) meet, are located at a minimal distance from the opposite electrode (12, 11) greater than (d), provided that the corresponding electrode (11, 12) is separated from the wall (9a) by a gap (3) whose width is less than (d).

摘要： A discharge plasma device includes a discharge tube (A). The discharge tube (A) has a hermetic vessel (1) filled with a discharge gas. The hermetic device (1) contains a pair of discharge electrodes (2a, 2b), an electron source (3) for supplying electrons into the discharge gas, and a grid electrode (4) opposing the electron emitting surface of the electron source (3). The discharge plasma device includes power source (5) for applying voltage across the discharge electrodes (2a, 2b), discharge detection means (6) for detecting a discharge state of the discharge tube (A), and control means (7) for controlling the potential of the electron source (3) so as to suppress collision of plus ions to the electron source (3) when discharge start of the discharge tube (A) is detected by the discharge detection means (6). The grid electrode (4) has an opening for passing electrons emitted from the electron source (3). The electron source (3) and the grid electrode (4) constitute a discharge plasma generation auxiliary device.

摘要： A device suitable for switching large currents includes, within a gas filled envelope, an anode (1), electrodes (2 and 3) and a thermionic cathode (4). Initially, the device holds off a voltage until a triggering pulse is applied to electrode (3). This causes an electron current to be established between the thermionic cathode (4) and anode (1). When the current reaches a sufficiently large value, further conduction through the device occurs via current drawn from the surface of the electrode (2) in cold cathode mode, bypassing the cathode (4).

摘要： An electrical discharge apparatus, such as a gas laser, in which a glow discharge is to be produced in a gas between two electrodes (1, 2), at least one pre-ionising member (5, 6) is placed near the discharge space and extending between the electrodes so that current flows in the member which is made of intermediate resistivity material such as crystalline semi-conductor material. As a result, the discharge space is pre-ionised which assists initiation of the main discharge. The pre-ionisation may be due to the formation of numerous small arcs between the electrodes and the member and the resulting production of ultra-violet light.
摘要翻译：一种放电装置，例如气体激光器，其中在两个电极（1,2）之间的气体中产生辉光放电，至少一个预电离部件（5,6）放置在放电空间附近并且在电极之间延伸，使得电流在由诸如结晶半导体材料的中等电阻率材料制成的构件中流动。结果，放电空间被预电离，这有助于主放电的开始。预电离可能是由于在电极和构件之间形成许多小弧，并且由此产生紫外光。
