Descripción
IFMIF-DONES is intended to be a powerful source of fast neutrons and as such it is of interest for various scientific and technology communities. Facility for Complementary Experiments is a part of DONES designed to broaden the scientific potential of the installation. With a dedicated experimental area of almost 300 m2 the facility will provide on-demand access to collimated neutron beam whenever the DONES Test Cell is operating.
The facility relies on major components: a neutron beam tube (NBT) which leads neutrons from the Test Cell to the room 160, a neutron beam shutter (NBS) which controls the neutron bram and ensures radiological safety for room R160 where the experiments with neutrons will take place.
At current conceptual it is expected that room 160 could facilitate from one up to 6 scientific setups depending on their size.
With the Neutron Shutter opened, according to neutronic simulation the room will provide access to collimated fast neutron beam of around 2·1014 m-2s-1 that can be delivered to research setups installed in R160.
Proposed design of NBS ensures safe for personnel radiological conditions in the R160 even during irradiations in the DONES Test Cell. Additionally proposed design of Neutron Beam Shutter shall also be fail-safe which means that under any failure (e.g. blackout) the NBS shall get its closed position in a highly reliable way.
Apart from high intensity Collimated neutron beam, the Facility for Complementary Experiments will provide scientific setups with necessary space, and media such as gasses and liquids.
The facility may be adjusted for potential application of FCE capabilities such as nuclear physics, applications of medical interest, basic physics studies and industrial application of neutrons.
The presentation will cover current assumptions, goals and ongoing efforts focusing on most imporant aspects of facility design.
