Neutron Capture Measurements on Minor Actinides at the n_TOF Facility at CERN : Past, Present and Future

The successful development of advanced nuclear systems for sustainable energy production and nuclear waste management depends on high quality nuclear datalibraries. Recent sensitivity stud- ies and reports [1-3] have identi ed the need for substantially improving the accuracy of neutron cross-section datafor minor actinides. The n TOF collaboration has initiated an ambitious exper- imental program for the measurement of neutron capturecross sections of minor actinides. Two experimental setups have been constructed for this purpose: a Total Absorption Calorimeter (TAC) [4] for measuring neutron capturecross-sections of low-massand/or radioactive samples and a set of two low neutron sensitivity C6D6 detectors for the less radioactive materials.
