Abstract A poloidally varying electrostatic potential due to a plasma heating anisotropic in velocity space is investigated in the collisionless regime for an axisymmetric plasma. Based on a linearized drift kinetic equation in a presence of external energy-source term, an analytic expression for this electrostatic potential is derived by means of an eigenfunction technique and a variational method. By using this analytic expression, the enhancement of the neoclassical transport coefficients by the anisotropic heating is discussed.
