Abstract

Power supply lines (41, 42) connect poles of an alternating current power source (43) to respective cathodes (58, 59) in compartments (32, 39), included among a plurality of adjacent compartments (32-39'), which together form a vacuum chamber (31) and which are connected to each other by a passageway (60). The two compartments (32, 39) with the cathodes (58, 59) are separated from each other by intermediate compartments (32'-38'), at least some of which are equipped with additional sputter cathodes (61-66).
