Abstract
Introduction of a magnetic spectrometer for the analysis of nuclear reaction products can open a new dimension in structure studies as well as reaction studies through the capability of achieving high-resolution and low-background measurements. Ion-optical matching methods to achieve better energy (momentum) resolutions than those inherent to the incident beam causing the reaction are described for a magnetic spectrometer using beams from an accelerator. They are the lateral dispersion matching, focus matching and also the kinematic correction. In addition the angular dispersion matching should be performed if better resolution of the scattering angle is important. These conditions are described in the first order approximation of ion optics. The diagnostic methods to realize the conditions of lateral dispersion matching and angular dispersion matching condition are briefly presented. The method described here can be applied for a good resolution spectroscopy of a reaction using a beam from ion source or a secondary beam with a larger energy spread.
