Ion flux transmission along an insulating duct with an axial magnetic field

Mostrar todas las versiones(3)

An experimental study of the metallic ion flux in a pulsed copper vacuum arc with an annular anode and operated with an axial magnetic field is presented. It is employed an insulating drift duct surrounded by an external coil which generates an axial magnetic field. Operating the arc under vacuum co...
