Influence of chamber temperature on properties of the corona discharge system

This paper investigates the influence of the chamber temperature on properties of the corona discharge system. It is found that the critical voltage V-c required for the corona discharge breakdown is inversely proportional to the chamber temperature T. The electrical energy w(c) required for corona discharge breakdown is inversely proportional to the square of the chamber temperature T. Thus, the electrical energy consumption for the corona discharge system decreases significantly as the temperature increases. The plasma generation by corona discharge in a hot chamber is much more efficient than that in a cold chamber. (C) 1999 American Institute of Physics. [S1070-664X(99)00802-2].
