However, such a corona generator element cannot generate uniform negative mode corona. It has been found that when a metal wire is used to generate a negative

In order to compensate for this phenomenon and to generate a corona that is substantially uniform, various solutions have been proposed. One is to use one

FIG. 1 shows a corona generator element in its entirety <EMI ID = 14.1>

  
corona generator element 11 on the top surface 17.

  
The corona generator element 11 consists of a wire 19,

very intensive coronas substantially uniformly distributed over the entire length of the wire 19.

  
 <EMI ID = 19.1> lie in a plane going through the longitudinal axis of the wire 19. The slightly inclined portion 29 has a thickness smaller than the diameter.

  
 <EMI ID = 20.1>

When the wire 19 is energized, the corona power supply 13 will generate a very intensive corona along the sharp edges 27 of each portion 25. The final result is

The thin planar portions 21 and diamond-shaped portions 25 are disposed close together along the length of the wire 19, resulting in a substantially uniform over the entire length of the wire.

Naturally, the resulting corona generator element can also be used in the positive mode.
