Abstract
Each electrode comprises a shaft (,) and a head (,), the shaft being sealed in a vacuum-tight fashion in each case in an end region (,) of the discharge vessel. At least one electrode is cooled by virtue of the fact that its shaft contains a cooling tube system in which a coolant (,) circulates. Said cooling tube system is surrounded at a spacing by an additional enveloping tube (,), the interspace (,) between the enveloping tube and cooling tube system being fitted with a means of thermal insulation.
