Abstract

The gas discharge cell has connections through which refrigerating medium is pumped and is used for plasma chemistry and laser techniques. The device has a hollow metal casing (1) covered with a layer (5) of high temperature dielectric material. This may be in the form of a foil. In the emission zone (2) is a metal layer (6) which may be mobium or titanium. In another design, is a plate shaped extension (7) across the top of the metal casing (1) which exters a slot (2) across a cover (10) in the emission zone. Alternatively, instead of plate, the top surface has a pattern of pegs which pass through holes in the cover (10).

Description

(54) ЭЛЕКТРОДНЫЙ ЭЛЕМЕНТ Э.ПЕКТРОРАЗРЯДНОГО ЛАЗЕРА(54) ELECTRODE ELEMENT E. PECTRO DISCHARGE LASER

Изобретение относитс  к области квантовой электроники и может быть использовано при создании электроразрлдных лазеров.The invention relates to the field of quantum electronics and can be used to create electro-discharge lasers.

Известны электродные элементы, из которых набираетс  электродна  плата электроразр дного лазера fl. .Каждый электродный элемент в этом устройстве представл ет собой по- . лый металлический брусок с плоской рабочей стенкой, покрытой снаружи, за исключением эмиттирующего участка на нем, слоем высокотемпературного диэлектрика, внутренний объем бруска соединен патрубками с системой охлаж жени . Слой высокотемпературного диэлектрика, нанесенного наповерхность металлического бруска, практически всегда имеет отдельные дефекты (микротрещины, микропоры), которые привод т к электрическим пробо м между отдельными элементами и выходу из стро  электродной платы.Electrode elements are known from which the electrode of the electric discharge laser fl is accumulated. Each electrode element in this device is a. A metal bar with a flat working wall, covered outside, with the exception of the emitting section on it, with a layer of high-temperature dielectric, the internal volume of the bar is connected by pipes to the cooling system. A layer of high-temperature dielectric deposited on the surface of a metal bar almost always has separate defects (microcracks, micropores), which lead to electrical breakdowns between individual elements and failure of the electrode plate.

Известны также электродные элементы , из которых набрана электродна  плата лазера того же типа 2 . На рабочей поверхности каждого из этих электродных элементов, составл ющих плату, выполнен выступ, а слой высокотемпературного диэлектрика изготовElectrode elements are also known, of which a laser electrode of the same type 2 is dialed. A protrusion is made on the working surface of each of these electrode elements constituting the board, and a layer of high-temperature dielectric is made

лен в виде составного чехла, состо lijero из корпуса, в котором размещен полый металлический брусок (вкладыш) и крышки с днищем, причем в днище выполнена прорезь, в которую входит выступ. Так как материалы крышки и эмиттера имеют разные коэффициенты линейного расширени , тов процессе работы в диэлектрической крышке возникают упругиеНапр жени , привод щие к растрескиванию диэлектрика, что снижает над1Ежность работыэлектродного элемента. В процессе изготовлени  элементы составного чехла крышка и корпус, изготавливаемые из высокотемпературного: диэлектрика, проход т обжиг при температурах, при которых материал корпуса и крышки переходит в пластическое состо ние.Flax in the form of a composite cover, consisting of a body in which a hollow metal bar (liner) and a lid with a bottom is placed, with a slot in the bottom that includes a protrusion. Since the materials of the cover and the emitter have different linear expansion coefficients, elastic workloads occur in the dielectric cover, leading to cracking of the dielectric, which reduces the electrical potential of the electrode element. In the process of manufacturing, the elements of the composite cover, the cover and the case, made of high-temperature: dielectric, are fired at temperatures at which the material of the case and the cover turns into a plastic state.

Это приводит к изменению геометрической формы деталей, особенно крьЕцки, в днище которой выполнена прорезь, снижающа  жесткость конструции . Это затрудн ет сборку электродных элементов.This leads to a change in the geometrical shape of the parts, especially krietski, in the bottom of which a slot is made, reducing the rigidity of the structure. This makes it difficult to assemble the electrode elements.

Цель изобретени  - повышение надежности и упрощени  технологии изготов .лени  электродного элемента.The purpose of the invention is to increase the reliability and simplify the manufacturing technology of the electrode element.

Это достигаетс  тем, что эмиттер выполнен составнцм в виде заклепокThis is achieved by the fact that the emitter is made in the form of rivets.
