A computerized Langmuir probe system [PDF]

Review of Scientific Instruments, 2003
For low pressure plasmas it is important to record entire single or double Langmuir probe characteristics accurately. For plasmas with a depleted high energy tail, the accuracy of the recorded ion current plays a critical role in determining the electron temperature.

Characteristics of the Contaminated Langmuir Probe [PDF]

Journal of Astronomy and Space Sciences, 1995
Korea's third rocket, which is currently under development for launch on 1997, is expected to reach as high as 160km and thus, it will provide a good opportunity for the direct measurement of the plasmas in the E-region ionosphere of the Korean peninsula.

Determination of Self-Neutralization Phenomena of Ion Beams with Langmuir Probe Measurements and PIC-DSMC Simulations [PDF]

Applied Sciences
Small mN-class gridded ion thrusters are usually tested in a vacuum chamber without the use of a neutralizer, relying on self-neutralization of the ion beam due to interaction with facility walls.

Langmuir Probe Technique for Plasma Characterization during Pulsed Laser Deposition Process

Coatings, 2021
The history of pulsed laser deposition (PLD) and transient plasmas generated by laser ablation is intertwined with the development of various techniques for its fundamental understanding. Some diagnostic tools have been developed to better suit the rapid

The influence of probe spacing and probe bias in a double Langmuir probe setup

AIP Advances, 2021
Multi-needle Langmuir probes are mounted on satellites and sounding rockets for high-frequency characterization of plasma in the ionosphere. Mounted on a spacecraft, the recorded probe current often differs from expected results.

Triple Langmuir probe calibration in TOMAS ECRH plasma

AIP Advances, 2023
In the TOMAS device, a triple Langmuir probe is used to measure the electron temperature and density. The accuracy of this measurement depends on correct determination of the effective collecting area of the probe, which depends on complex plasma ...

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 ...

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 ...
