Studies of Rare Gas-Sodium Arcs with the Use of Collertors

Abstract

In the He, He+Na, Ne, Ne+Na, A, A+Na ares with hot eathodes the SPAN Potential, electron current denalty and electron temperature were determined by probe method(1) near the eatbode and anode and in the positive column. The variations of cathode fall, potential gradient in the positive column, anode fall and of electron temperature with the kind of rare gases and with vapor premure of sodium were studied from the above measurementa
