Journal ArticleDOI

Performance of the neutron time-of-flight facility n_TOF at CERN

Carlos Guerrero, +116 more
TL;DR: In this paper, the authors present the characteristics of the new neutron beam in the currently available configurations, which correspond to two different collimation systems and two choices of neutron moderator, including the intensity and energy dependence of the neutron flux, the spatial profile of the beam, the in-beam background components and the energy resolution/broadening.
Journal ArticleDOI

7Be(n, p)7Li Reaction and the Cosmological Lithium Problem: Measurement of the Cross Section in a Wide Energy Range at n_TOF at CERN

Mario Barbagallo, +133 more
TL;DR: The energy-dependent cross section of the ^{7}Be(n,α)^{4}He reaction, of interest for the so-called cosmological lithium problem in big bang nucleosynthesis, has been measured for the first time from 10 meV to 10 keV neutron energy.
Journal ArticleDOI

The new vertical neutron beam line at the CERN n_TOF facility design and outlook on the performance

C. Weiß, +136 more
TL;DR: The design of the beam line and the experimental hall was based on FLUKA Monte Carlo simulations, aiming at maximizing the neutron flux, reducing the beam halo and minimizing the background from neutrons interacting with the collimator or backscattered in the beam dump as discussed by the authors.
Journal ArticleDOI

The n_TOF Total Absorption Calorimeter for neutron capture measurements at CERN

Carlos Guerrero, +117 more
TL;DR: The Total Absorption Calorimeter (TAC) as discussed by the authors was designed for measuring neutron capture cross-sections of low-mass and/or radioactive samples with the accuracy required for nuclear technology and stellar nucleosynthesis.
Journal ArticleDOI

The data acquisition system of the neutron time-of-flight facility n_TOF at CERN

U. Abbondanno, +110 more
TL;DR: A scalable and versatile data solution has been designed based on 8-bit flash-ADCs with sampling rates up to 2 GHz and 8 Mbyte memory buffer for high accuracy measurement of neutron capture, fission and (n, xn) cross-sections at CERN.
