 Measurement of the 235 U(n,f) cross section at n_TOF from thermal to 170 keV / Amaducci, Simone ; Amaducci, S ; Aberle, O ; Andrzejewski, J ; Audouin, L ; Bacak, M ; Balibrea, J ; Barbagallo, M ; Bečvář, F ; Berthoumieux, E et al. The $^{235}$U(n,f) cross section plays a key role for nuclear physics due to its widespread use as a standard reference for neutron cross section measurements and for neutron flux measurements. Recent experimental data of the fission cross section have suggested the presence of discrepancies around 6–8% with respect to the most used libraries, precisely in the range between 10 keV and 30 keV.

 A Proton Recoil Telescope for the characterisation of the neutron beam at n_TOF / n_TOF Collaboration The neutron induced fission cross section of $^{235}$U is extensively used as a reference for neutron fluence measurements in various applications. At intermediate energies, the $^{235}$U(n,f) cross section plays an important role also for fundamental nuclear physics.

 Status and perspectives of the neutron time-of-flight facility n_TOF at CERN / Mingrone, F (CERN) ; Massimi, C (Bologna U.) /n_TOF Collaboration The neutron time-of-flight facility of CERN, called n_TOF, started its operation in 2001, and since then it plays a major role in the field of neutron cross-section measurements. The two beam-lines available provide an excellent combination of good energy resolution and high instantaneous neutron flux, combining the time-of-flight method with a powerful neutron spallation source.

 n + $^7$Be Cross-Sections of Astrophysical Interest at the CERN n_TOF Facility / Mastromarco, Mario (CERN ; Manchester U.) ; Damone, Lucia Anna (INFN, Bari ; Bari U.) ; Barbagallo, Massimo (CERN ; INFN, Bari) /n_TOF Collaboration One of the possible explanations of the so-called Cosmological Lithium Problem (CLIP), i.e., the large overestimate of the primordial$^7$Li abundance by the standard Big Bang Nucleosynthesis theory (BBN), is related to an incorrect underestimation of the 7 Be destruction rate by neutron-induced reactions. To verify this possibility, the n + $^7$Be reactions have been investigated at n_TOF (CERN) in a wide neutron energy range, taking advantage of the new high-flux experimental area (EAR2) and specifically developed experimental setups.

TORCH is a time-of-flight detector, designed to provide charged $\pi/K$ particle identification up to a momentum of 10 GeV/c for a 10 m flight path. To achieve this level of performance, a time resolution of 15 ps per incident particle is required. [...] arXiv:1812.09773.- 2020-02-01 - 4 p. - Published in : Nucl. Instrum.

 Review and new concepts for neutron-capture measurements of astrophysical interest / n_TOF Collaboration The idea of slow-neutron capture nucleosynthesis formulated in 1957 triggered a tremendous experimental effort in different laboratories worldwide to measure the relevant nuclear physics input quantities, namely ($n,\gamma$) cross sections over the stellar temperature range (from few eV up to several hundred keV) for most of the isotopes involved from Fe up to Bi.

One of the reactions that could have an impact on the problem is $^7$Be(n,p)$^7$Li.
