Performance of the reaction-product transport line associated with the TOFI spectrometer

Abstract

A reaction-product transport line with a solid-angle acceptance of 2.8 msr and a momentum-to-charge acceptance of 28% has been constructed to deliver neutron-rich nuclei produced in heavy-target fragmentation reactions to the time-of-flight isochronous (TOFI) spectrometer. The design and performance of the transport line, which incorporates a mass-to-charge filter to reduce the rate of uninteresting ions entering the spectrometer, is described.
