Measurement and analysis of electron-neutral collision frequency in the calibrated cutoff probe
K. H. You,Shin-Jae You,Dae-Woong Kim,Byung-Keun Na,Byonghoon Seo,Jin-Gyu Kim,Hong-Young Chang +6 more
TL;DR: Kim et al. as mentioned in this paper measured the electron-neutral (e-n) collision frequency in the plasma using a calibrated cutoff-probe, and compared the measured e-n collision frequency with that obtained using a Langmuir probe, with the latter being calculated from the measured electron energy distribution functions, in wide range of gas pressure.

Measurement of electron density using reactance cutoff probe
K. H. You,Shin-Jae You,Dae-Woong Kim,Byung-Keun Na,Byonghoon Seo,Jin-Gyu Kim,D. J. Seong,Hong-Young Chang +7 more
TL;DR: In this article, the reactance spectrum of the plasma in the cutoff probe system instead of the transmission spectrum was measured using the full two-port error correction and automatic port extension methods of the network analyzer.

Reproducibility of the cutoff probe for the measurement of electron density
Dae-Woong Kim,Shin-Jae You,Joonhyuk Kwon,K. H. You,Byonghoon Seo,Jin-Gyu Kim,Jin-Hui Yoon,Wang-Yuhl Oh +7 more
TL;DR: In this paper, a comparative study among the different cutoff probe measurements was performed, which revealed remarkable result: the cutoff probe has a great reproducibility for the electron density measurement, i.e., there are little differences among measurements by different probes made by different experimenters.

Investigation of reliability of the cutoff probe by a comparison with Thomson scattering in high density processing plasmas
TL;DR: In this paper, the authors compared the accuracy of the cutoff probe with Thomson scattering in a low temperature, high density processing plasma and showed that the discrepancy of the two results becomes smaller as the gap between the two tips increases and/or the neutral gas pressure decreases.
Determination of a macro- to micro-scale progression leading to a magnetized plasma disruption
TL;DR: In this paper, the authors report the observations of a plasma jet evolving through a macro-to micro-scale progression sequence, leading to a fast magnetic reconnection that results in the jet breaking off from its originating electrode and forming a force free state.
