Zusammenfassung

Ultrahochvakuum mit Basisdruck von weniger als 5 × 10−10 mm Hg wird routinemässig erzeugt und für mehrere Monate mittels einer Öldiffusionspumpe aufrechterhalten. Eine mit aktivierter Alumina beschickte Isolationsfalle von grossem Querschnitt ist zwischen Pumpe und Glassystem eingesetzt; so wird ohne irgendwelche Kühlung das Zurückströmen von Öldämpfen in die Experimentierapparatur vollkommen verhindert.
