Radially Convergent Proton Beams from a Cylindrical Double Diode.
Abstract
A cylindrical double diode is used to produce a radially convergent proton beam. This device exhibits both pinching and, to a lesser degree, reflexing of the electrons. The proton current density incident on the inner cathode is larger than the ion current density anticipated for bipolar space charge flow. The current density of ions extracted through the cathode has been intensified by at least a factor of 7 as a result of geometric focusing. (Author)
