摘要:

A tantalum hollow cathode used in an argon ion laser as an electron emitter for large currents is described. If the emitter is used in combination with an auxiliary anode, which serves as a starting electrode and as an evaporation shield, we found this cathode a good choice especially for large currents in excess of 100 A.
