Use of Mach probes and Langmuir probes in a drifting unmagnetized nonuniform plasma

Conference Oksuz, L ; Hershkowitz, N

Although Mach probes have been used to measure the ion drift velocities in fusion plasma applications, their operation in unmagnetized plasma is less well understood. The effects of nonuniform drifting plasma on Langmuir probes and Mach probes have been investigated in a multi-dipole plasma. The Mach probe data were collected for different probe sizes and for different noncollecting part biases. Controlling the voltage of the noncollecting part of the mach probe makes the collecting part of the I-V traces less noisy. While different biases applied to the noncollecting part perturbed the collected data, the current ratios didn't change if themore »« less

Edge effect correction for small planar Langmuir probes

Journal Article Johnson, J D ; Holmes, A J.T. - Review of Scientific Instruments; (USA)

One problem inherent in the use of small planar Langmuir probes to analyze low-density plasma is expansion of the space-charge sheath with increased probe potential due to the departure from planarity caused by a nonnegligible sheath edge. Experimental evidence showing the existence of significant edge effects in the ion saturation region of the characteristic obtained from such probes is presented. The extra ion current {Delta}{ital I}{sub +} collected as a result is shown to depend on the (negative) probe potential {ital V} according to the empirical relation {Delta}{ital I}{sub +}{proportional to}{ital V}{sup 0.75}. A theoretical justification for this is obtained.more »« less

Digital smoothing of the Langmuir probe I-V characteristic

Journal Article Magnus, F ; Gudmundsson, J T ; Department of Electrical and Computer Engineering, University of Iceland, Hjardarhaga 2-6, IS-107 Reykjavk - Review of Scientific Instruments

Electrostatic probes or Langmuir probes are the most common diagnostic tools in plasma discharges. The second derivative of the Langmuir probe I-V characteristic is proportional to the electron energy distribution function. Determining the second derivative accurately requires some method of noise suppression. We compare the Savitzky-Golay filter, the Gaussian filter, and polynomial fitting to the Blackman filter for digitally smoothing simulated and measured I-V characteristics. We find that the Blackman filter achieves the most smoothing with minimal distortion for noisy data.

Influence of Ohmic resistance of a cylindrical Langmuir probe on its I - V characteristic

Journal Article Shun'ko, E V - Review of Scientific Instruments; (United States)

The distortion of the cylindrical Langmuir probe {ital I}-{ital V} characteristic, connected with the ohmic resistance of its operating element, is investigated. The relations given in the paper enable one to reconstruct the shape of the undistorted {ital I}-{ital V} characteristic from the experimental data.
