摘要：
A space charge lens is proposed to focus intense beams of negative hydrogen ions. The focal length of the lens is determined as a function of the parameters of the beam and the gas medium. It is demonstrated experimentally that the lens efficiently focuses H-ion beams with currents of up to ∼30 mA and energies of ∼10 keV. The measured focal lengths are in good agreement with the calculated ones.
