Abstract
The dynamic ergodic divertor (DED) perturbation coil system of TEXTOR is designed to be resonant with the magnetic field lines of the q = 3 surface at r(res) = 43 cm and for beta(pol) = 1. These parameters dete rmine the pitch of the perturbation coils. In this section the effect of a deviation from the design parameters is analyzed. It is found tha t-within reasonable limits-a deviation from the design parameters can be compensated by a repositioning of the plasma and-or a variation of the plasma current.
