Advances in neutron-induced resonance reaction cross section studies at GELINA

Abstract

Abstract. The neutron time-of-flight facility GELINA at the IRMM Geel, Belgium has been especially designed for neutron-induced reaction cross section studies in the resonance region. It is a multi-user facility, serving up to 10 different experiments simultaneously, and providing a pulsed white neutron source, with a neutron energy range between 1 meV and 20 MeV, a time resolution of 1ns and flight path lengths ranging from 10 m to 400 m. The main effort of the experimental program at GELINA is devoted to applied research. Over the last decade, the IRMM has made an intense effort to improve the quality of neutron-induced cross section data in the resolved and unresolved resonance region. Due to the progress made, neutron-induced reaction cross section data, including full covariance information, can be obtained at GELINA from thermal up to the unresolved resonance region.

Development of 24 and 59 keV Filtered Neutron Beams for Neutron Capture Experiments at Dalat Research Reactor

“…A new beam line for accurate neutron capture cross sections measurements with used a high resolution 4π Ge spectrometer has been developed at the J-PARC facility [3]. The neutron time-of-flight facility GELINA, with a neutron flight path lengths ranging from 10 m to 400 m, has been especially designed for neutron-induced reaction cross section measurements [4]. An inexpensive aspect of neutron sources for reaction cross studies is the use of filtered neutron beams from research reactors.…”
