The n_TOF facility at CERN is a neutron Time-Of-Flight facility based on a spallation neutron source. During the Second Long Shutdown (LS2) , a new experimental zone was designed and delivered. This new experimental area -the NEAR station - is located very close to the lead spallation target, at a distance of just ~3m. In this way, the high luminosity of the n_TOF neutron spallation source can be fully exploited. Towards the characterization of the new experimental area as well for the benchmarking of the performed simulations, the multi-foil activation measurement will be implemented. Eleven threshold and seven capture reference reactions will be utilized for the unfolding of the NEAR neutron beam energy spectrum that stretches from the meV to the GeV region.
During the second long shutdown period of the CERN accelerator complex (LS2, 2019-2021), several upgrade activities took place at the n_TOF facility. The most important have been the replacement of the spallation target with a next generation nitrogen-cooled lead target. Additionally, a new experimental area, at a very short distance from the target assembly (the NEAR Station) was established. In this paper, the core commissioning actions of the new installations are described. The improvement in the n_TOF infrastructure was accompanied by several detector development projects. All these upgrade actions are discussed, focusing mostly on the future perspectives of the n_TOF facility. Furthermore, some indicative current and future measurements are briefly reported.
Studies of (n, cp) reactions are important for a variety of fields, such as Nuclear Astrophysics, Nuclear Medicine, and nuclear energy applications. Accordingly, towards the development of innovative detection systems that could address these needs, within this contribution, the proposed validation of a new annular neutron-Transmutation Doped (nTD) double-sided silicon strip detector (DSSSD) will be overviewed. The most important characteristics will be given along with the expected performance and abilities within the n_TOF facility at CERN. Furthermore, the adopted particle identification technique based on pulse shape discrimination will be outlined. Finally, some preliminary experimental results will be discussed.
