【Abstract】 The emission character and discharge character of a purchased LaMo cathode material applied in high current ion source are measured. It is found that the LaMo cathode is an efficient heat cathode emitter. When used in high current ion source, the cathode arc is in normal operation and the lifetime of cathode is longer than that of LaB 6. From the practical use of this cathode, the LaMo cathode is indecd a new kind applicable cathode of high current ion source.更多还原
