Method of the nanosecond microstructure creation of the negative ion beam

Abstract

The method of the nanosecond microstructure creation of the negative ion beam with nanosecond edge times is presented. The method of creation does not destroy the beam compensation by the residual gas, so it is available for low-energy beams. Such effects as a beam divergence and, therefore, a bad beam transport are overcome. The two-plate travelling wave chopper is used. The special shape of the plate deflecting voltage is needed. The estimations and a comparison with the existing methods of a beam deflection are presented.
