The probe is the spherical part, 50 mm in diameter and made from titanium with a surface coating of titanium nitride. 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 electrodes into a plasma, with a constant or time-varying electric ...
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.
2009-059B. Orbit. Low Earth. 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 ( ESA) Proba 2. [1]
Plasma oscillation. Plasma oscillations, also known as Langmuir waves (after Irving Langmuir), are rapid oscillations of the electron density in conducting media such as plasmas or metals in the ultraviolet region. The oscillations can be described as an instability in the dielectric function of a free electron gas.
PROBA-2. PROBA-2 is the second satellite in the European Space Agency 's series of PROBA low-cost satellites that are being used to validate new spacecraft technologies while also carrying scientific instruments. [3] PROBA-2 is a small satellite (130 kg) developed under an ESA General Support Technology Program (GSTP) contract by a Belgian ...
The Langmuir adsorption model explains adsorption by assuming an adsorbate behaves as an ideal gas at isothermal conditions. According to the model, adsorption and desorption are reversible processes. This model even explains the effect of pressure; i.e., at these conditions the adsorbate 's partial pressure is related to its volume V adsorbed ...
Dynamics Explorer 2 (DE-2 or Explorer 63) was a NASA low-altitude mission, launched on 3 August 1981. It consisted of two satellites, DE-1 and DE-2, whose purpose was to investigate the interactions between plasmas in the magnetosphere and those in the ionosphere. The two satellites were launched together into polar coplanar orbits, which ...
Explorer 27 (or BE-C or Beacon Explorer-C, Beacon-C or S-66C) was a small NASA satellite, launched in 1965, designed to conduct scientific research in the ionosphere. [ 2] It was powered by 4 solar panels. One goal of the mission was to study in detail the shape of the Earth by way of investigating variations in its gravitational field. [ 3]
