New experimental evidence of the correlation between edge sheared E×B flow and reduction of turbulence has been measured in the CASTOR tokamak (R = 0.4 m, a = 0.085 m, B T = 1 T). A biasing electrode is placed at the separatrix in a configuration wh

The interaction of high power lower hybrid waves with tokamak plasma results in a range of favourable but also unfavourable effects. This article deals with the effects observed by Langmuir probes on the small tokamak CASTOR. The most pronounced effe

Strong fluctuations of lower hybrid waves (LHW) amplitudes inside the plasma have been observed in experiments with different types of launchers. The fluctuation frequency is much higher than the frequency of plasma density fluctuations. This effect

Magnetic and electrostatic fluctuations are measured in the CASTOR tokamak with a reasonable spatial and temporal resolution to better understand the nature of turbulent processes in tokamaks. We have found that the broadband magnetic fluctuations in

Measurements of the radial magnetic field fluctuations, B{sub r}, have been performed with two sets of movable radial magnetic probes which are toroidally spaced in one set and poloidally spaced in the other set. The root mean square values (RMS) of

A diagnostic impulse arc source of a beam of lithium atoms was used for the measurement of electron density profile in front of the lower hybrid grill on the CASTOR tokamak. It was shown that this profile is modified significantly during lower hybrid

The plasma edge of the CASTOR tokamak ( R = 0.4 m, a = 0.1 m) has been investigated using a thermal lithium beam. The radial profiles of the electron density have been derived from the radiation profiles of the excited lithium atoms at λ = 671nm. Pr
