We report experimental observations of a low-frequency (≪ ion gyrofrequency) electrostatic wave mode in a magnetized cylindrical (Q machine) plasma containing positive ions, very few electrons and a relatively large fraction (n−/ne > 103) of heav

Linear and nonlinear analysis are presented for an electronegative dusty plasma system. Linear analysis shows that the dispersive nature of the plasma system changes considerably due to the presence of nonthermal q-nonextensive distributed electrons.

Experimental results are presented on the nonlinear effects related to the simultaneous excitation of three low-frequency instabilities in the magnetized plasma column of a Q-machine, namely the potential relaxation instability, the electrostatic ion

The specific history of collisionless drift waves is marked by focusing upon current-driven, shear-modified, and electron-temperature-gradient modes. Studies of current-driven collisionless drift waves started in 1977 using the Innsbruck Q machine an

An array of baffled probes for the real-time monitoring of oscillating values of space potential, electric field and electron/ion temperature in magnetized plasma is assembled and tested. The multi-probe array samples a region with dimensions on the

Dust ion-acoustic shocks in a Q machine device are considered. For their description the so-called hydrodynamic ionization source model is used. The model is appropriate for the description of the laboratory experiments in a Q machine device and cont

Q machines, which produce low-temperature, stationary and fully-ionized plasmas in magnetic fields, have been operated for over four decades. The results obtained using the Q machine have greatly contributed toward systematizing plasma physics. Their

Radial profiles of ion flow vd(r) are measured with laser-induced fluorescence for cases in which the flow direction is parallel (vd>0) and/or antiparallel (vd
