Hg is increased to 100 to 300 mm Hg. The reduction of the radial distance between the coaxial electrodes requires no precision in the assembly of the electrodes. This promotion is achieved within the framework of the increase in price by the fact that the widened base part of the rod-shaped electrode is used as an electrode of coaxial cylinder with the same The outer diameter is designed as a nolalzylin & riscäie electrode and as the centering part of the rod electrode is aligned with the hollow cylindrical surface. If the outer jacket surfaces of the two electrodes match, there is therefore a reliable guarantee for the genstxe coaxiality of the active conductive surfaces.
