General Information on Pseudospark


Historical background

In the late 1950's J. Chritiansen worked on parallel plate avalancehe counters for nuclear phyusic experiments. Near the Paschen minimum, anomalous sparks at the edge zones of these counters resulted in erratic failures. Twenty years later he reestablished the research in this almost forgotten effect. quote from K. Frank and J. Christiansen, IEEE Trans. Plasma Sci. 17, 748 (1989).

In 1979, J. Christiansen and C. Shultheiss published a paper Production of high current particle beams by low pressure spark discharges, in Z. Phys. A 290, 35 (1979). In this paper, a low pressure fast discharge phenomenon between a hollow cathode and an anode is described and named as pseudo-spark.
