CURRENT DISTRIBUTION OF A SEGMENTED HALL GENERATOR,
Abstract
The paper describes an experimental and theoretical investigation of the current distribution in a segmented Hall generator with conductive side walls and insulating side walls respectively. The cathode emits in the arc mode; whereas the anode is an equi-potential. The current concentrates in the middle portion of the cathode and is very unsteady. The anode portion appears to be steady and the current spreads out somewhat evenly. The external load has little influence on the anode current distribution. In all load conditions, there is about 60% of the current flow into the anode, 15% flows to one side wall and 25% to the other side wall. The potential distribution on the anode side wall is linear and with a maximum potential drop of 40 volts. The cathode side wall appears to be an equi-potential surface. (Author)
