Untersuchungen zu den Existenzbereichen und Typen von ac‐Entladungen. II. Das Verhalten der Entladungstypen in Ne/Ar‐Gemischen und der Vergleich mit Ne/N₂‐Gemischen

Abstract

The investigations on the transition between the discharge modes in Ne-N, mixtures are described in [l]. I n the present paper we investigate Ne-Ar mixtures with a view to comparing the behavionr of these different mixtures. The measurements confirm the transition mechanism between the bistable pulse mode and the non-bistable continuous mode in Ne-Penning mixtures. The life time of metastable atoms is important for the existence of the continuous mode. If the life time is changed by varying the cross sections for the Penning ionization QP (e.g. in other mixtures), the transition frequency of both these discharge modes shows a corresponding shift, which, for both mixtures, is in good agreement with literature values of Qp. The second part presents a study of the quasiglow mode. The transition between the pulse mode and the quasiglow mode correlates to the ion transit time. The three discharge modes are represented in the existence diagram.
