چکیده
It is demonstrated that a frequency selective Alfvén-wave resonator can be realized by applying a nonuniform magnetic field to a plasma region bounded between a cathode and a semitransparent mesh anode. When a current threshold is exceeded, selective amplification results in a highly coherent, large amplitude wave that propagates into an adjacent plasma column.

Differential equation model of an Alfvén wave maser
A mathematical model describing the operation of an Alfvén wave maser in a laboratory environment is constructed from a continuous differential equation. The model incorporates the essential features of maser operation, namely, a resonator with a semitransparent boundary, a unidirectional amplification region, and a nonuniform magnetic field that provides frequency filtering. The spectral featu...
متن کاملAn Alfvén wave maser in the laboratory
A frequency selective Alfvén wave resonator results from the application of a locally nonuniform magnetic field to a plasma source region between the cathode and anode in a large laboratory device. When a threshold in the plasma discharge current is exceeded, selective amplification produces a highly coherent sdv /v,5310−3d, large amplitude shear Alfvén wave that propagates out of the resonator...
متن کاملLaboratory realization of an ion‐ion hybrid Alfvén wave resonator
[1] In a magnetized plasma with two ion species, shear Alfvén waves (or guided electromagnetic ion cyclotron waves) have zero parallel group velocity and experience a cut‐off near the ion‐ion hybrid frequency. Since the ion‐ion hybrid frequency is proportional to the magnetic field, it is possible, in principle, for a magnetic well configuration to behave as an Alfvén wave resonator in a two‐io...
متن کاملCan Resonant Oscillations of the Earth Ionosphere Influence the Human Brain Biorhythm?
Within the frames of Alfvén sweep maser theory the description of morphological features of geomagnetic pulsations in the ionosphere with frequencies (0.1-10 Hz) in the vicinity of Schumann resonance (7.83 Hz) is obtained. It is shown that the related regular spectral shapes of geomagnetic pulsations in the ionosphere determined by ”viscosity” and ”elasticity” of magneto-plasma medium that cont...
متن کاملDirect measurement of electron sloshing of an inertial Alfvén wave
We report laboratory measurements of the parallel current carried by suprathermal electrons associated with inertial Alfvén wave excitation in the laboratory. The experiments presented here use a novel wave absorption diagnostic that measures the suprathermal tails of the electron distribution parallel to the mean magnetic field. The diagnostic is used to probe the electron distribution as an i...
