A microwave conductor (20,20' . . .) is connected with a generator (19,19' . . .) for igniting a plasma in the area of channels formed by a sheet-metal shroud (2,2') matching the configuration of the hollow body (4). A closure (7,7') is provided through which the filler opening (6, 6') of the hollow body (4) can be closed pressure-tight, and a line (9,9') for the process gas passes through the closure.
