Langmuir Probe experiments

Experiment: Electrical Probes in a Plasma

Location:  Institute of Interfacial Process Engineering and Plasma Technology, University of Stuttgart

Description:  Two different types of electrical probes are used to investigate the plasma parameters in a glow discharge depending on external control parameters: the single Langmuir probe and the double Langmuir probe.

Target group:  The experiment is intended for master students and part of a general practical course. The size of the group is usually two students.

Use and access: Due to being part of a practical course, the experiment is regularly in use. Depending on the availability, use by other groups is in general possible.
