Descripción
Neutron-dominated mixed field irradiation testing stations at CERN are employed for scientific, technological, and industrial application. Currently operating infrastructure include the NEAR irradiation station at the n_TOF facility and a similar infrastructure at ISOLDE, called ISIS (ISOLDE Irradiation Station). NEAR is operating to the neutron time-of-flight (TOF) facility n_TOF [1] served by a Pb spallation target and producing a high-intensity pulsed white-spectrum neutron field covering almost 11 orders of magnitude, from thermal neutrons to several GeV. Close to the neutron source target, a “i-NEAR station” is located, focusing on MGy/y material. In parallel, thanks to an opening in the target area shielding a “a-NEAR station” [2] is operated, focusing on activation for physics measurements. A similar facility, ISIS, is operating parasitically downstream the ISOLDE targets, in a mixed proton/neutron field. In a longer term, a potential high-intensity facility in the CERN’s North Area, if coupled with a high-Z production target [3], will provide a unique source of mixed field radiation (up to 400 MGy/y), coupled with access to high intensity proton beam could be equipped with (semi) parasitic facilities. The goal of this talk will be to give a brief overview of existing and future testing station opportunities at CERN.
