Integral Experiments in the GELINA Target Hall – 238U and natCu: Description of the first two integral experiments in the GELINA target hall

This report describes the first two integral experiments carried out in the GELINA target hall. In these experiments neutron and gamma flux attenuation through large thickness of materials is measured. The results are of interest for nuclear data evaluators as a means of validation of neutron inelastic scattering cross sections. The GELINA pulsed white neutron source has recently been employed to perform two such measurements, 238U and natCu. A 15-cm stack of several depU disks available at JRC Geel were used in the first experiment, and a 60-cm stack of six natCu plates form ENEA, Frascati, were used in the second. Activation foils of various materials were used between the disks to measure the neutron flux. The feasibility to perform experiments of this type in the GELINA target hall was proven, and the data analysis is ongoing.
