Abstract
Original neutron generator on the base of pulse accelerating vacuum tube with two targets, symmetrically located on both sides of deuteron source, is discussed. Two immersion lenses in front of each other use as accelerating and focusing systems. Lenses cathodes are Faraday cups with targets for neutron production on the bottom. Symmetric ring magnetic elements cover immersion lenses for correcting focusing conditions. Computer simulation allows us to choose electrodes geometry and accelerating pulse value for electron flow from ion–electron emission oscillate between the targets and provide device operation as reflex triode. Estimations show that four times less energy for deuteron flow acceleration requires to obtain neutron flow production at the level of the best sealed accelerating tubes with the same tube geometry sizes.
