Neutron Inelastic Scattering Experiments using GAINS at GELINA
A considerable effort was dedicated during last years to the upgrade of the setup used for measurements of neutron inelastic cross sections at GELINA. The completely renewed setup called GAINS (Gamma Array for Inelastic Neutron Scattering) is now operational at a 200 m flight path of the white neutron source GELINA.
GAINS consists of eight high-efficiency HPGe detectors placed at 110o and 150o in close geometry around the sample. The acquisition system is based on four 12 bits, 420 MHz digitizers with two input channels each.
The reliability of the system was already proven for 206Pb data (based on a comparison with a former measurement) and is now under further investigation via a 56Fe measurement.
The present contribution describes the new system together with the analysis method. It further emphasizes the difficulties of a highly accurate 56Fe(n, n¿¿) measurement and shows the preliminary available results.
