Description

"Vorrichtung zum Erzeugen von erzwungener Infrarotemission, IraserK "Apparatus for Generating Forced Infrared Emission, Iraser K

Die Erfindung bezieht sich auf eine Vorrichtung zum Erzeugen von erzwungener Infrarotemission, einen Iraser, mittels einer elektrischen Entladung in Kohlensäuregas, dem Stickstoff und Helium zugesetzt sind.The invention relates to a device for generating forced infrared emission, an Iraser, by means of an electrical discharge in carbonic acid gas to which nitrogen and helium are added.

Bei bekannten Irasern enthält die Gasfüllung ausserdem Wasserdampf mit einem Druck von einigen Zehnteln Torr zur Erhaltung eines optimalen Gemisches mit höherem Wirkungsgrad und höherer ausbeute. Argon und Krypton haben einen ungünstigen Einfluss auf den Wirkungsgrad und der Druck dieserIn known iras, the gas filling also contains Water vapor at a pressure of a few tenths of Torr to maintain an optimal mixture with higher efficiency and higher yield. Argon and Krypton have an unfavorable one Influence on the efficiency and the pressure of this

Es hat sich herausgestellt, dass der Zusatz des Wasserdampfes nicht nur eine Verdopplung des Wirkungsgrades und der Ausbeute ergibt, sondern dass ausserdem die Lebensdauer bedeutend verlängert wird.It has been found that the addition of water vapor not only doubles the efficiency and the yield, but also that the service life is significantly extended.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. An embodiment of the invention is shown in the drawing and is described in more detail below.

In der Zeichnung ist 1 ein ^uarzrohr mit einer Länge VQn 1,5 Ja und einer lichten Weite von 20 mir.. 2 ist ein h-»hl geschliffener '^uarzblock, Krümmungsradius 2,4 n, der mit einer Goldschicht 3 bedeckt ist. 4 ist eine flache Germaniumplatte mit einer Dicke von 2 mm. Hohle Platinzylinder 5 und 6 in den Seitenrohren bilden die Elektroden.In the drawing, 1 is a quartz tube with a length of 1.5 and a clearance of 20 mm. 2 is a h- »hl ground '^ uarzblock, radius of curvature 2.4 n, which with a gold layer 3 is covered. 4 is a flat germanium plate with a thickness of 2 mm. Hollow platinum cylinders 5 and 6 in the side tubes form the electrodes.

Die Füllung des Kohrs besteht aus 1 Torr CO2, 2,5 Torr N2, 11 Torr He und 0,2 Torr H0. Bei einem Entladestrom von 40 mA und. einer Betriebsspanmmg von gut 1 3»5 kV tritt bei 7 ein Bündel mit einer Fellenlänge von 10,6 /un und einer Intensität von 60 W aus. Der Wirkungsgrad beträft also 11 $. Die Lebensdauer beträgt über 1Ü00 Jtunden.The filling of the tube consists of 1 Torr CO 2 , 2.5 Torr N 2 , 11 Torr He and 0.2 Torr H 0 . With a discharge current of 40 mA and. With an operating voltage of a good 1 3 »5 kV, a bundle with a fur length of 10.6 / un and an intensity of 60 W emerges at 7. So the efficiency is $ 11. The service life is over 100 hours.
