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

The n_TOF neutron time-of-flight facility features a white neutron beam produced by spallation through 20 GeV/c protons impinging on a lead target. The facility, aiming primarily at the measurement of neutron-induced reaction cross sections, has been operating at CERN since 2001 and underwent a major upgrade in 2008, which marked the start of the second phase (n_TOF-Phase2) experimental program. This paper presents in detail all 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. The characteristics discussed include the shape and intensity of the neutron flux, the spatial profile of the beam, the in-beam background components and the energy resolution/broadening. The discussion of these features is based on dedicated measurements and on Monte Carlo simulations, and includes estimations of the systematic uncertainties in the mentioned quantities.
