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

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.

Whistler waves are a common feature of ionospheric and magnetospheric plasmas. While the linear behavior of these waves is generally well understood, a number of interesting observations indicate that much remains to be learned about the nonlinear ch

Laboratory observations of oscillatory motion of charged microparticles have been made in an argon dc glow discharge plasma created within a strong dc magnetic field. Measurements of the oscillation frequency and amplitude are consistent with the gyr

Laboratory experiments have been conducted to simulate the dynamics of highly localized magnetospheric boundary layers. These regions, such as the plasma sheet boundary layer and the magnetopause, are primary regions of solar wind mass, energy, and m

A method for approximating arbitrary axial magnetic field profiles for a given solenoidal electromagnet coil array is described. The method casts the individual contributions from each coil as a truncated orthonormal basis for the space within the ar

Summary form only given. There have been a number of interesting in situ and laboratory observations of whistler wave propagation and stimulated emissions over the past few decades. For example, Stenzel [1975] reported on the self-ducting of large am
