Space-charge lens for focusing negative ion beam
The idea of a space-charge lens for focusing intensive negative hydrogen ion beams is presented. Estimations of focal length of the lens are performed independent of parameters of the beam and gaseous medium. The effectiveness of the focusing H − ion beam with current up to ∼30 mA and energy of ∼10...
