Orthogonal directions constrained gradient method for beam optics correction

An Orthogonal Directions Constrained Gradient Method (ODCGM) has been developed and experimentally used for optimization and correction of H- optical beam parameters for laser assisted charge exchange injection (LACE) experiments. LACE experiment requires precise tune up of H- beam parameters for high efficiency stripping. High precision tuning of beam parameters cannot be done in one step due to miscellaneous errors of power supplies and other factors. Then, subsequent application of the optic correction method considered here can do fine tune up of the beam. A simple experimental demonstration of ODCGM is presented.
