THPSC51	Ion Source Deuteron Beam Acceleration in Gas-filled Ion-optic System	444

	Deuteron beam acceleration in ion-optic system of gas-filled neutron tubes was investigated. PIC code SUMA* used for computer simulation of ionization and knock on processes and there influence on deuteron beam parameters. When deuteron and ionized particles space charge self-field forces become the same order of magnitude as external one, virtual cathode may occurs. It is happens because of injected from ion source deuterons cannot overcome their own space charge potential wall and move in transverse direction. However, electrons, produced by ionization, are trapped within the deuteron beam space charge potential wall and decrease it significantly. Thus, space charge neutralization of deuteron beams by electrons, may considerably increase target current and, as a result, output neutron flow. Moreover, own longitudinal electric field rise near the target leads to reduction of accelerating electrode – target potential wall, which was made to prevent knock on emission from the target. As a result, additional knocked on electrons may appear in the region and should be taken into account. The data obtained were compared with experimental results. * A.N. Didenko, V.I.
