Description
A large multicusp negative ion source has been constructed to generate H- or D- ions for high-energy neutral beam systems. With the presence of cesium, the source has produced a steady-state H- ion beam current greater than 1 A with an impurity level less than 1%. The vertical and horizontal profiles of the self-extracted beam have been measured with a gridded Faraday cup. The gas efficiency of the source and the electron component in the accelerated beam have been measured for two different pumping conditions
