This paper is concerned with plasma properties of a medium-vacuum nitrogen arc discharge with the titanium cathodes. The arc chamber used is 400 mm in diameter and 600 mm, respectively. The experimental conditions are as follows: Pressure range = 1 {times} 10{sup {minus}3} {approximately} 2 {times} 10{sup {minus}1} torr; N{sub 2} gas flow rate = 6 ml/min; arc current = 50 A. Electric probe characteristics are measured as a function of pressure and distance from the cathode surface. The analytical results obtained from these measurements show that the electron energy distribution takes 1-Mx at pressures above 1 {times} 10{sup {minus}2} torr, whereas 2-Mx at pressure under 4 {times} 10{sup {minus}2} torr and the electron density have a maximum value at a certain pressure.
