<p>A compound plasma configuration can be formed from a device having pins (116), and an annular electrode (111) surrounding the pins (116). A cylindrical conductor (110) is electrically connected to , and coaxial with, the annular electrode (111), and a helical conductor (118) coaxial with the cylindrical conductor. The helical conductor (118) is composed of a plurality of wires with each wire connected to each pin (116). The annular electrode (111) and the pins are disposed in the same direction away from the interior of the conducting cylinder.</p> |
