Spacecraft data reveals a nonuniform ambipolar electric field transverse to the magnetic field in a thin magnetotail current sheet that leads to intense ExB velocity shear and non-gyrotropic particle distributions. The ExB drift far exceeds the diama

Plasma impedance probes are often used in laboratory experiments as well as in space to make measurements of important plasma parameters such as the electron density. Conventional impedance probe methods involve sweeping the frequency applied to the

Electron extraction from a hollow cathode plasma discharge through a primary anode, biased with a dc accelerating potential, is modulated to produce pulsed or continuous electron beams without the interruption of the plasma cathode discharge. This is

Impedance probe measurements are made at ionospheric (F-region) plasma conditions ( $n_{e}\approx 10^{4}$ – $10^{6}$ cm $^{-3}$ and $\lambda _{D}\approx 1$ –10 cm) created in the Space Physics Simulation Chamber at the Naval Research Laboratory.

Electron extraction from a hollow cathode plasma discharge through a primary anode, biased with a DC accelerating potential, is controlled to produce either a pulsed or a continuous electron beam without interruption of the discharge. The beam is on

For a wide variety of laboratory and space plasma environments, theoretical predictions state that plasmas are unstable to inhomogeneous flows over a very broad frequency range. Such sheared flows are generated in the Earth's magnetosphere and intens

A small RF signal is applied to the anode of a low pressure (P ≤ 200 mTorr), low temperature (Te ≤ 3 eV) direct current (DC) glow discharge operating at an electron density of ne ∼ 106 cm-3. The discharge is modeled as a collection of capacitiv
