Summary
As part of the IFMIF-DONES project, we propose to study and define the performance of a neutron line dedicated to various applications such as neutron imaging or scattering. These studies will be carried out using the Geant4-based TOUCAN code. They will be used to define the lines that will be installed in the facility.
Full description
The IFMIF-DONES facility (International Fusion Materials Irradiation Facility DEMO Oriented Neutron Source) is currently under construction in Granada (Spain). It will be dedicated to the irradiation and study of materials used for the structure and cladding of a nuclear fusion reactor. It will produce an unprecedented flow of neutrons over an energy range of up to 50 MeV. A large proportion of these neutrons will not interact with the irradiated materials, and will be lost. This is why it is planned to use some of these neutrons for other applications in a dedicated adjacent room. Possible uses are still being defined, but a preliminary study carried out by our team [1] has shown that IFMIF-DONES has the potential to be a first-class facility.
In this internship, we propose to continue the work started in [1], by studying and defining neutron lines that can be used for various applications such as radiography of objects, to probe materials by neutron scattering, or to produce radioelements. The work will involve simulating the entire neutron transport chain, from slowing neutrons down in the moderator to detecting them, using the Geant4-based code TOUCAN. The aim will be to assess the performance of such lines, and to optimize the moderator-extractor combinations that will improve performance.
This work will complement that already carried out, and will be the starting point for choosing and defining the characteristics of the instruments that will take their place in the installation.
