A Langmuir probe is a device used to determine the electron temperature, electron density, and electric potential of a plasma. It works by inserting one or more ...
The Planar Langmuir Probe (PLP) is a dual-disk probe designed to provide in situ measurements of plasma density and density fluctuations. Low time-resolution density measurements are intended as inputs for background ionosphere models and high time-resolution density irregularity measurements to specify disturbance conditions.
This is known as the single-probe method. (b) The surface areas are very small in comparison with the dimensions of the vessel containing the plasma and approximately equal to each other. This is the double-probe method. Conventional Langmuir probe theory assumes collisionless movement of charge carriers in the space charge sheath around the probe.
Irving Langmuir (/ ˈ l æ ŋ m j ʊər /; [2] January 31, 1881 – August 16, 1957) was an American chemist, physicist, and metallurgical engineer.He was awarded the Nobel Prize in Chemistry in 1932 for his work in surface chemistry.
Dual Segmented Langmuir Probe (DSLP) is an instrument developed primarily by Czech researchers and engineers to study the magnetospheric background plasma flown on board the spacecraft of the European Space Agency Proba 2. [1] Data acquired by DSLP will be used to reach these specific scientific goals: [2]
Schematic picture of a single ball-pen probe. Ions (in red) have a large gyromagnetic radius and can reach the collector more easily than electrons (in blue). A ball-pen probe [1] is a modified Langmuir probe used to measure the plasma potential [2] in magnetized plasmas. The ball-pen probe balances the electron and ion saturation currents, so ...
In 1964, the General Electric Foundation took over the financial backing of the prize, which was renamed the Irving Langmuir Award and the modern selection process was created. In 2006 the GE Global Research took over sponsorship of the award, and since 2009 the award has been co-sponsored between GE Global Research and the ACS Division of ...
High frequency Langmuir probe (LP): Two novel high frequency Langmuir probes developed by PRL to measure electron density and fluctuations. In double mounted configuration One probe will perform the sweep and other will monitor plasma potential. [5] [4] Electron Temperature Analyser (ETA) by SPL [5]
