CERN's Upgraded n_TOF Facility and New NEAR Experimental Station Now Operational

CERN's neutron time-of-flight (n_TOF) facility has transitioned into its fourth operational phase following comprehensive infrastructure upgrades completed during the second long shutdown (LS2) from 2019 to 2021. Key developments include the replacement of the spallation target with a third-generation assembly and the establishment of an entirely new NEAR experimental station, situated approximately three meters from the spallation target, designed to provide an extraordinarily high neutron flux for activation and irradiation studies. The facility is now ready to support challenging nuclear physics investigations, including actinide fission studies and experimental validations of neutron beam filtering techniques.
