Abstract
AbstractAn active fission target has been developed for the FIPPS instrument at ILL, enabling for the first time an efficient suppression of $$\upbeta $$
β
-delayed $$\upgamma $$
γ
rays in high-resolution and high-efficiency $$\upgamma $$
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$$\pi $$
π
fragment detection. Measurements have been performed with $$^{233, 235}$$
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 $$\upgamma $$
γ
-ray spectroscopy studies of fission fragments.
