The first linear global electromagnetic gyrokinetic particle simulation on the excitation of toroidicity induced Alfvén eigenmode (TAE) by energetic particles is reported. It is shown that the long wavelength magnetohydrodynamic instabilities can be studied by the gyrokinetic particle simulation. With an increase in the energetic particle pressure, the TAE frequency moves down into the lower continuum together with an increase in the linear growth rate.

    Stochastic heating of dust particles resulting from dust charge fluctuations is considered in some laboratory situations, where high kinetic temperatures of dust particles have been suggested or could be observed. A particular case, in the conditions of the scrape-off layer in tokamak plasmas,...
