| description | A new high flux experimental area has recently become operational at the n TOF facility at
CERN. This new measuring station, n TOF-EAR2, is placed at the end of a vertical beam line at a
distance of approximately 20 m from the spallation target. The characterization of the neutron beam, in
terms of flux, spatial profile and resolution function, is of crucial importance for the feasibility study and
data analysis of all measurements to be performed in the new area. In this paper, the measurement of the
neutron flux, performed with different solid-state and gaseous detection systems, and using three neutron-
converting reactions considered standard in different energy regions is reported. The results of the various
measurements have been combined, yielding an evaluated neutron energy distribution in a wide energy
range, from 2 meV to 100 MeV, with an accuracy ranging from 2%, at low energy, to 6% in the high-energy
region. In addition, an absolute normalization of the n TOF-EAR2 neutron flux has been obtained by
means of an activation measurement performed with 197Au foils in the beam. |
