Collisional drift waves in stellarator geometry

Collisional drift waves, in the linear approximation and for low-β plasmas, are studied in stellarator geometry. A system of three coupled, partial differential equations, describing the perturbed density, electrostatic potential and electron temperature, is derived. This system of equations is solved as an initial-value problem along the magnetic field line. Numerical results for the toroidal heliac H1-National Facility [S. M. Hamberger et al., Fusion Technol. 17, 123 (1990)] are presented.
