- Abstract
An active fission target has been developed for the FIPPS instrument at ILL, enabling for the first time an efficient suppression of β -delayed γ rays in high-resolution and high-efficiency γ -ray spectroscopy of fission fragments at a neutron beam. The target is based on a liquid scintillator in which the actinide is dissolved, resulting in a 4 π fragment detection. Measurements have been performed with 233 , 235 U, with a fission tagging efficiency of 97.8(25)%. The high efficiency, together with the good time resolution of the scintillator target, provide high-selectivity data for γ -ray spectroscopy studies of fission fragments.
