Abstract

Experimental data on obtaining electron beam by the magnetron gun with a cold cathode are presented. Two possible emission mechanisms such as electron secondary emission and explosive emission as well as methods of identifying it are discussed. Data on measuring amplitude and form of the beam current pulses and the beam diameter with variation of the electric and magnetic fields are given. The final aim of this research is production of a stable pulse beam with currents of nearly 100 amperes and a long lifetime of the gun. The research has been carried out to create a magnetron injection gun for the high power cluster klystron for the Next Linear Colliders
