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 ...
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.
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 ...
A Langmuir–Taylor detector, also called surface ionization detector or hot wire detector, is a kind of ionization detector used in mass spectrometry, developed by John Taylor [1] based on the work of Irving Langmuir and K. H. Kingdon.
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. The frequency depends only weakly on the ...
Irving Langmuir was born in Brooklyn, New York, on January 31, 1881.He was the third of the four children of Charles Langmuir and Sadie, née Comings. During his childhood, Langmuir's parents encouraged him to carefully observe nature and to keep a detailed record of his various observations.
A test probe is a physical device used to connect electronic test equipment to a device under test (DUT). Test probes range from very simple, robust devices to ...
