Abstract
The technique of emission current stabilization for high current guns is considered. It is based on the using of two anodes. The first one is powered through the resistor and has floating potential due to small current intercept. This approach allows decreasing variations of beam current more than two orders of magnitude at fluctuations of emission or anode voltage
