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.
