Measurement of the nTOF beam profile in the second experimental area (EAR2) using a silicon detector

A new beam line and a second experimental area (EAR2) have been recently built at the neutron Time-Of-Flight (nTOF) facility at CERN. The characterization of the neutron beam in terms of spatial profile is a prerequisite for high accuracy cross-sections measurements. A silicon strip detector equipped with a neutron converter has been used to determine the beam profile as a function of incident neutron energy, in particular neutron beam profile has been measured from thermal energy up to 10 eV. Preliminary results have been compared with those collected with a MicroMegas detector also installed during the measurement.
