The optimum conditions for focusing a negative ion beam are discussed. The distribution of the current between the Faraday cup and a large ring collector, surrounding this cup, has been investigated experimentally and theoretically, at constant extraction voltage (1.9 kV), with the acceleration voltage being varied in a wide range. The effects of beam space charge, negative ion temperature, and stripping are analyzed.
