Cryo-cooled high-power window for high-frequency plasma heating. Thermodynamic study of the single-disk concept with liquid nitrogen edge cooling

Technical Report:

Abstract

Within the framework of gyrotron window development, IMF pursues the concept of a single-disk window with edge cooling. Compared to a double-disk window with surface cooling, this concept offers a number of advantages in terms of safety, reliability, and ease of design and fabrication. The coolants which can be used for this purpose are liquid nitrogen and helium at very low temperature. (orig.). [Deutsch] Im Rahmen der Gyrotronfensterentwicklung wird vom IMF das Konzept eines Einscheiben-Fensters mit Randkuehlung verfolgt. Dieses Konzept bietet gegenueber dem Doppelscheibenfenster mit Flaechenkuehlung mehrere Vorteile in den Punkten Sicherheit, Zuverlaessigkeit und einfache Bauweise. Als Kuehlmittel kommen fluessiger Stickstoff und Helium bei sehr niedriger Temperatur in Betracht. Im vorliegenden Bericht werden thermodynamische Rechnungen zur Randkuehlung mit fluessigem Sticksotff behandelt. Es werden Auswirkungen von verschiedenen Parametern und Faktoren auf die Leistungsgrenze gezeigt. (orig.).
