Stacking data analysis method for Langmuir multi-probe payload

Frontiers in Astronomy and Space Sciences
There are numerous small-scale electron density irregularities in the ionosphere. The coordination of multiple needle Langmuir probes (m-NLPs) enables in situ measurement of electron density with high spatial resolution. However, the theoretical analysis

Real-time control of divertor detachment in H-mode with impurity seeding using Langmuir probe feedback in JET-ITER-like wall

, 2017
Burning plasmas with 500 MW of fusion power on ITER will rely on partially detached divertor operation to keep target heat loads at manageable levels. Such divertor regimes will be maintained by a real-time control system using the seeding of radiative ...

Comparison between IRI and preliminary Swarm Langmuir probe measurements during the St. Patrick storm period

Earth, Planets and Space, 2016
Preliminary Swarm Langmuir probe measurements recorded during March 2015, a period of time including the St. Patrick storm, are considered. Specifically, six time periods are identified: two quiet periods before the onset of the storm, two periods ...

Diagnostics of low-pressure capacitively coupled RF discharge argon plasma

Iraqi Journal of Physics, 2019
Low-pressure capacitively coupled RF discharge Ar plasma has been studied using Langmuir probe. The electron temperature, electron density and Debay length were calculated under different pressures and electrode gap.

Development of the Langmuir probe under q-distribution for NCST

AIP Advances
The Langmuir probe is one of the important diagnostic methods for measuring the edge plasma parameters of tokamak. A quadruple Langmuir probe (QLP) system was designed and built on the NanChang Spherical tokamak (NCST).

Estimation of electron temperature for SiO2 plasma induced by laser

Iraqi Journal of Physics, 2019
In this work; Silicon dioxide (SiO2) were fabricated by pulsed laser ablation (PLA). The electron temperature was calculated by reading the data of I-V curve of Langmuir probe which was employed as a diagnostic technique for measuring plasma properties.

Real-time phase-selective data acquisition system for measurement of wave phenomena in pulsed plasma discharges [PDF]

, 1998
A novel data acquisition system and methodology have been developed for the study of wave phenomena in pulsed plasma discharges. The method effectively reduces experimental uncertainty due to shot-to-shot fluctuations in high repetition rate experiments.
