New method of H- beam diagnostics

In the considered method of the H- beam diagnostics the information on beam parameters is taken out via the fast H degree atoms which are produced in definite quantum states at the charge-exchanging area of the transport line. The beam parameters are determined in the convenient area outside the transport line by means of a compact magnetic analyzer and electrons produced from a selective photoionization of the useful quantum state of the H degree atoms. The realization of such diagnostics at the area of the charge-exchanging H-→P injection of the meson factory storage rings is considered. If the information on the H- beam parameters is taken out via the fast H degree atoms in metastable 2s-quantum state the accuracies of correspondence between electron and ion distributions ∼10-2% in energy and ∼3x10-5 rad in angle coordinate can be obtained
