n_TOF Collaboration(Cano-Ott, D. et al), Domingo-Pardo, C., & Tain, J. L. (2011). Neutron Capture Measuremetns on Minor Actinides at the n_TOF Facility at CERN: Past, Present and Future. J. Korean Phys. Soc., 59(2), 1809–1812.
Abstract: The successful development of advanced nuclear systems for sustainable energy production and nuclear waste management depends on high quality nuclear data libraries. Recent sensitivity studies and reports [1-3] have identified the need for substantially improving the accuracy of neutron cross-section data for minor actinides. The n_TOF collaboration has initiated an ambitious experimental program for the measurement of neutron capture cross sections of minor actinides. Two experimental setups have been constructed for this purpose: a Total Absorption Calorimeter (TAC) [4] for measuring neutron capture cross-sections of low-mass and/or radioactive samples and a set of two low neutron sensitivity C(6)D(6) detectors for the less radioactive materials.

n_TOF Collaboration(Sanchez-Caballero, A. et al), Babiano-Suarez, V., Balibrea-Correa, J., Domingo-Pardo, C., Ladarescu, I., & Lerendegui-Marco, J. (2026). Low-uncertainty measurement of the 239Pu(n,f) cross section at n_TOF in a very broad energy range from 0.02 eV up to 10 MeV. Phys. Lett. B, 872, 140070–8pp.
Abstract: The Pu-239(n,f) cross section was measured with uncertainties below 4% from 20 meV up to 10 MeV of neutron energy at CERN's n_TOF facility using a novel fission fragment detector with a 185.59 m flight path. Measured cross section was normalized to 1059(6) eV center dot b in the 9-20 eV energy range, and is consistent within uncertainties with the standard thermal value and the IAEA reference Pu-239(n,f) cross section. Experimental key values include the integral ratio I-3/I-1= 41.20(42) defined by Duran et al. 2024 and the spectrum averaged cross section in Cf-252(sf) reference neutron field of 1802(40) mb.
