Abstract
A resistance heating system prevents the generation of magnetic fields by constructing the heating section as a looped current circuit. The heating current circuit as a whole is connected to the potential in order to, at the same time, use the heating section in a process chamber as a process electrode. In an AC-connection of the heating current circuit, a capacitive shielding prevents a reaction of the electrode operating potential with respect to the primary side of a transforming heating current actuator.
