An RF Excited Plasma Cathode Electron Beam Gun Design
Sofia del Pozo, Colin Ribton, David R. Smith

Cite as:

A plasma cathode electron beam (EB) gun is presented in this work. A radio frequency (RF) excited plasma at 84 MHz was used as the electron source to produce a beam power of up to 3.2 kW at -60 kV accelerating voltage. The ...  read more

Investigation of long-life cathode EB guns for welding of turbochargers
Sofia del Pozo, Colin Ribton

Cite as:

This paper describes a laser heated cathode gun design which uses a lanthanum hexaboride button in a diode configuration. Beam currents up to 40 mA at – 60 kV were generated by using laser powers in the range of 19 to 83 ...  read more
