Measurements of the time evolution of the current-density distribution in ASDEX show that lower-hybrid current drive leads to broader profiles, whereby q increases from qapprox. 1 in the plasma central region. Simultaneously, the electron temperature

The electromagnetic fields excited by an azimuthally symmetric gap in a plasma filled waveguide are described as a superposition of radial eigenmodes. This results in a radially confined energy flow along the resonance cone. The effect of a finite ga

Interaction of lower hybrid waves at 1.3 GHz with ions and electrons was studied in the density range 0.2-5*1013 cm-3 in the ASDEX tokamak. At high densities, ne>or approximately=4*1013 cm-3, fast ions with mainly perpendicular velocities are produce

The authors consider an array of azimuthally symmetric gaps in a plasma filled waveguide at a frequency omega > omega LH. Using normal mode analysis they calculate the input admittance seen at each gap, which depends upon the relative distance, phase

The sawtooth oscillations in tokamak discharges with Ohmic and neutral-beam heating could be suppressed when a large part of the plasma current was driven by lower-hybrid waves (I/sub HF//I/sub p/approx. =0.5). The stabilization is due to a flattenin

The Buchsbaum-Hasegawa equation describing the r.f. electric field within a one-dimensional magnetoplasma slab has been re-derived from first principles. In a laboratory plasma the electron collisions are sufficiently numerous, in which case the mult
