Abstract
The study of the resonant structures in neutron-nucleus cross-sections, and therefore of the compoundnucleus
reaction mechanism, requires spectroscopic measurements to determine with high accuracy the energy of
the neutron interacting with the material under study. To this purpose, the neutron time-of-flight facility n_TOF has
been operating since 2001 at CERN. Its characteristics, such as the high intensity instantaneous neutron flux, the
wide energy range from thermal to few GeV, and the very good energy resolution, are perfectly suited to perform highquality
measurements of neutron-induced reaction cross sections. The precise and accurate knowledge of these cross
sections plays a fundamental role in nuclear technologies, nuclear astrophysics and nuclear physics. Two different
measuring stations are available at the n_TOF facility, called EAR1 and EAR2, with different characteristics of intensity
of the neutron flux and energy resolution. These experimental areas, combined with advanced detection systems lead
to a great flexibility in performing challenging measurement of high precision and accuracy, and allow the investigation
isotopes with very low cross sections, or available only in small quantities, or with very high specific activity. The
characteristics and performances of the two experimental areas of the n_TOF facility will be presented, together with
the most important measurements performed to date and their physics case. In addition, the significant upcoming
measurements will be introduced.
