Abstract:

Experimental results are reported on the transport of an electron beam with current in excess of the vacuum space-charge limited value, in a configuration directly applicable to gyrotron oscillators. The vacuum space- charge limit is circumvented by the introduction of a neutralizing background plasma which is produced by an array of four plasma guns placed immediately downstream of the electron gun anode. Keywords Super vacuum currents Plasma neutralization Gyrotron.
