Online and FREE access to plasma physics experiments
Nukleonika, 2023 Remote controlled laboratories had a great push during the COVID-19 pandemic. In fact, they were already out there but lacking in visibility. This external trigger pushed the academy to face a global challenge to start offering remote experiments more ...

DC Langmuir Probe for Measurement of Space Plasma: A Brief Review [PDF]
Journal of Astronomy and Space Sciences, 2015 Herein, we discuss the in situ measurement of the electron temperature in the ionosphere/plasmasphere by means of DC Langmuir probes. Major instruments which have been reported are a conventional DC Langmuir probe, whose probe voltage is swept; a ...

Floating potential probe Langmuir probe data reduction results [PDF]
40th AIAA Aerospace Sciences Meeting & Exhibit, 2002 During its first five months of operations, the Langmuir Probe on the Floating Potential Probe (FPP) obtained data on ionospheric electron densities and temperatures in the ISS orbit. In this paper, the algorithms for data reduction are presented, and comparisons are made of FPP data with ground-based ionosonde and Incoherent Scattering Radar (ISR ...

The digital mirror Langmuir probe: Field programmable gate array implementation of real-time Langmuir probe biasing [PDF]
Review of Scientific Instruments, 2019 High bandwidth, high spatial resolution measurements of electron temperature, density, and plasma potential are valuable for resolving turbulence in the boundary plasma of tokamaks. While conventional Langmuir probes can provide such measurements, either their temporal or spatial resolution is limited: the former by the sweep rate necessary for ...

Comparative measurement of plasma potential with tube probe and Langmuir probe
AIP Advances, 2018 Plasma potential measurements using the conventional Langmuir probe may cause an error due to the space charge effect. To solve the problem, a tube probe is proposed in this study which can minimize the space charge effect by collecting electrons with an
