This paper presents the experimental pressure dependence, in the range 1.01 x 10(5)-1.6 x 10(5) Pa, of the I - V characteristic of a N-2 positive corona discharge. The pressure raise is related to the gas flow increase into the chamber where the corona is ignited. Experimental measurements confirm Townsend's I - V characteristic. For a fixed potential difference between the electrodes, corona currents decrease as the gas flow increases (pressure increase): this has been ascribed to a lower ionization rate close to the stressed electrode and a lower charge mobility in the drift region. Both these processes result in a lower current generated by the discharge

Abstract

This paper presents the experimental pressure dependence, in the range 1.01 x 10(5)-1.6 x 10(5) Pa, of the I - V characteristic of a N-2 positive corona discharge. The pressure raise is related to the gas flow increase into the chamber where the corona is ignited. Experimental measurements confirm Townsend's I - V characteristic. For a fixed potential difference between the electrodes, corona currents decrease as the gas flow increases (pressure increase): this has been ascribed to a lower ionization rate close to the stressed electrode and a lower charge mobility in the drift region. Both these processes result in a lower current generated by the discharge
