Description

After a halt of four years, the n TOF spallation neutron facility at CERN has resumed operation in November 2008 with a new spallation target characterized by an improved safety and engineering design, resulting in a more robust overall performance and effcient cooling. Therst measurement during the 2009 run has aimed at the full characterization of the neutron beam. Several detectors, such as calibrated ssion chambers, the n TOF Silicon Monitor, a Mi-croMegas detector with10B and235U samples,...[Show more]

dc.description.abstractAfter a halt of four years, the n TOF spallation neutron facility at CERN has resumed operation in November 2008 with a new spallation target characterized by an improved safety and engineering design, resulting in a more robust overall performance and effcient cooling. Therst measurement during the 2009 run has aimed at the full characterization of the neutron beam. Several detectors, such as calibrated ssion chambers, the n TOF Silicon Monitor, a Mi-croMegas detector with10B and235U samples, as well as liquid and solid scintillators have been used in order to characterize the properties of the neutron fluence. The spatial prole of the beam has been studied with a specially designed "X-Y" MicroMegas which provided a 2D image of the beamas a function of neutron energy. Both properties have been compared with simulations performed with the FLUKA code. The characterization of the resolution function is based on results from simulations which have been veried by the study of narrow capture resonances of56Fe, which were measured as part of a new campaign of (n,γ) measurements on Fe and Ni isotopes.
