Abstract
Electrical probes are an excellent tool for local measurements of basic plasma parameters, fluctuations and plasma flow studies. However, the application of a probe diagnostics is usually accompanied by theoretical restrictions, practical limitations and problems. In this paper we describe the new probe system recently developed for the TOMAS toroidal device (Forschungszentrum Jülich, Germany). This system comprises multi-collector Gundestrup probe for flow measurements and Langmuir probe for plasma characterization. During development of such a system, several physical and technical issues, which are common for probe applications, were solved or essentially suppressed.
