ROTATING WHEEL ELECTRODE DEVICE FOR GAS DISCHARGE SOURCES COMPRISING WHEEL COVER FOR HIGH POWER OPERATION

摘要

The present invention relates to an electrode device (1, 2) for gas discharge sources and to a gas discharge source having one or two of said electrode devices (1, 2). With the proposed design of the cover (8), an efficient cooling of the electrode wheel (7) is achieved, allowing high electrical powers for operating gas discharge sources with such an electrode device.
