At the neutron time-of-flight facility n_TOF at CERN a new vertical beam
line was constructed in 2014, in order to extend the experimental
possibilities at this facility to an even wider range of challenging
cross-section measurements of interest in astrophysics, nuclear
technology and medical physics. 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
back-scattered in the beam dump.
The present paper gives an overview on the design of the beam line and
the relevant elements and provides an outlook on the expected
performance regarding the neutron beam intensity, shape and energy
resolution, as well as the neutron and photon backgrounds.
