Abstract

Die Erfindung bezieht sich auf eine Vorrichtung zur Erzeugung eines Strahls von Atomen oder Radikalen durch thermische Dissoziation eines Gases, mit einem Rohr (1), das an seinem einen Ende an eine Gasquelle (2) anschließbar ist und an seinem anderen Ende eine Gasaustrittsöffnung (3) aufweist, und einer Heizvorrichtung (4), um das Rohr (1) zu erwärmen, welche dadurch gekennzeichnet ist, daß die Heizvorrichtung (4) wenigstens einen Heizdraht (5) zur Erwärmung des Rohrs (1) durch Wärmestrahlung aufweist und der Heizdraht (5) das Rohr (1) im Bereich der Gasaustrittsöffnung (3) unter Herstellung eines elektrischen Kontakts berührt, im übrigen aber mit Abstand umgibt.
