“…Many lessons were learned during the development of the different activities. These may be useful for future neutron source facilities such as DONES [22], F-ANS [23] or other installations involving accelerators with similar requirements. The main conclusions and lessons learned are the following:…”

The International Fusion Materials Irradiation Facility (IFMIF) is a project aiming to investigate candidate materials to be used in the most exposed zones of future fusion reactors. The Linear IFMIF Prototype Accelerator (LIPAc), presently under commissioning in Rokkasho, Japan, is a prototype of the frontend section of one of the IFMIF accelerators. Eight quadrupole magnets, six pairs of corrector magnets and one dipole are responsible of generating the magnetic fields needed for a proper beam handling along the ten meters long LIPAc High Energy Beam Transport line, which connects the end of the Superconducting Radio Frequency linac with the Beam Dump. A novel design of combined magnets with the correctors integrated in the quadrupole poles is chosen for compactness reasons. The different stages of the production of the combined magnets, from the magnetic and mechanical design to their manufacturing and testing, including exhaustive characterization of the magnetic performance are described in this work. The results from the tests revealed the quality of the magnetic field produced. The materials selection was done carefully, to withstand the high levels of ionizing radiation expected at the magnet locations. This paper focuses on the activities performed in Europe, before sending the magnets to Japan for their installation and commissioning at the Rokkasho site.

“…Its performance is limited by the power handling capability of the target. Facilities in which a D-beam interacts with light ions in liquid metals constitute the IFMIF family of devices, including the IFMIF proposal (Knaster et al, 2014)], IFMIF-DONES (Ibarra et al, 2017), A-FNS (Ochiai et al, 2020) and BISOL (Liu et al, 2019)). The principle is based on Li(d,xn) nuclear reactions taking place in a liquid Li target when bombarded by a deuteron beam.…”

“…The International Fusion Materials Irradiation Facility (IFMIF) is such a facility, and prototype components are presently being tested in a collaboration between Europe and Japan (Knaster et al, 2017). To accelerate the path to the realization of such a neutron source, Europe and Japan are now each proposing smaller neutron sources, IFMIF/DONES in Europe (Ibarra et al, 2018), and the Advanced Fusion Neutron Source in Japan (Ochiai et al, 2020). Spherical tokamak based devices have also been proposed as volumetric neutron sources, denoted 'Component Test Facility'.…”

An accelerator-based neutron source using d-Li reactions is one of the most promising neutron sources for fusion material irradiation facilities such as IFMIF, where 40 MeV deuterons bombard a liquid lithium target. The neutron yield estimation including angular neutron spectra is one of the most important issues in the design of such irradiation facilities. Recently, JAEA released deuteron nuclear data of JENDL/DEU-2020 in ACE format file for Monte Carlo codes such as MCNP, and in Frag-Data format for the PHITS code. We carry out the benchmark calculations of d-Li neutron yield by using PHITS with Frag-Data, MCNP with JENDL/DEU-2020, and MCNP/PHITS with built-in nuclear reaction models. Those calculation results are compared with experimental data. It is confirmed that PHITS with Frag Data and MCNP with JENDL/DEU-2020 reproduce well the experimental data. Those are useful for the neutron yield estimation and also the irradiation field characterization of IFMIF and similar facilities.
