Title: Nuclear spectroscopy with low energy reaction thermal neutrons in ILL


Abstract: Institute Laue-Langevin (ILL) is a reactor based European neutron source, which delivers neutron with highest intensity in the Europe for ~40 different instruments. There are two nuclear physics instruments in ILL, which use actinide targets. Lohengrin [1,2] is a fission recoil separator with very high mass and energy resolving power (A/ΔA =1500, E/ΔE = 100 1000). Series of successful experimental campaign was carried out with different detection setups such as fast timing, conversion electron and fission studies using fission fragments. The overview of the campaign and preliminary results of the experiments will be presented. FIPPS [3,4] is the new nuclear physics instrument of ILL for the prompt γ-ray spectroscopy of nuclei produced in neutron-induced reactions. Currently, (Phase 1) FIPPS consists of an 8 array of HPGe clover detectors and a pencil-like intense thermal neutron beam. The overview of the first fission experimental campaign with an active actinide target diluted in scintillator will be presented. In the near future upgrade of the instrument (phase 2) will be carried out using anti-Compton shield and the Gas-Filled-Magnet (GFM). The newly proposed GFM and physics opportunities in ILL will be discussed.
