Abstract
The invention provides a support member which carries at least one axially aligned corona electrode, and a conductive biasing member wrapped around both the support member and the electrode. The biasing member is preferably a wire wrapped about the support and electrode to form a coil and preferably there are four electrodes. A conductor extends the length of the coil to ensure continuity should the biasing member fail locally.
