Abstract
An upgraded detection setup for neutron scattering measurements was recently completed at the GELINA neutron source of IRMM. A 200 m flight path is used. Eight HPGe detectors are placed at 110° and 150° with respect to the neutron beam and are read-out by fast digitizers. The neutron flux is monitored by a ²³⁵U fission chamber. The first inelastic scattering measurement with the new setup was performed for ^natFe.
