Abstract : Three problems related to the effect of electrostatic trapping on dissipative trapped electron instabilities are investigated: (1) the linear theory of the dissipative trapped electron mode for the case in which there is both a magnetic well and an electric well (or anti-well), (2) the nonlinear stability of a drift wave (in a straight constant magnetic field) whose amplitude is large enough to trap electrons, and (3) the nonlinear saturation of the dissipative trapped electron mode in a tokamak-type magnetic well via the mechanism of electric trapping and detrapping by wave electrostatic potential perturbations along B.
