摘要
Results from comprehensive kinetic microinstability calculations are presented, showing the effects of toroidicity on the ion temperature gradient mode and its relationship to the trapped-electron mode in high-temperature tokamak plasmas. The corresponding particle and energy fluxes have also been computed. It is found that, although drift-type microinstabilities persist over a wide range of values of the ion temperature gradient parameter ηl ≡ (d ln Τl/dr)/ (d ln ni/dr), the characteristic features of the dominant mode are those of the ηi-type instability when ηi> ηic ∼ 1.2-1.4 and of the trapped-electron mode when ηi, < ηic. © 1990 American Institute of Physics.
