The neutron induced fission of $$^{235}$$U is extensively used as a reference for neutron fluence measurements in various applications. However, no data exist on neutron induced fission of $$^{235}$$U above 200 MeV. The neutron facility n_TOF offers the possibility to improve the situation. The measurement of $$^{235}$$U(n,f) relative to the differential n-p scattering cross-section, was carried out with the aim of providing accurate and precise cross section data in the energy range from 10 MeV up to 1 GeV. In this measurements, recoil proton telescopes are used to measure the neutron flux while the fission events are detected and counted with dedicated detectors. In this paper the measurement campaign and the experimental set-up are illustrated.
