论文摘要
IFMIF-DONES设施将致力于计划在未来的融合反应堆（例如演示融合发电厂）中使用的结构材料的辐射。在这项工作中介绍了IFMIF-DONES设施通过其他实验来补充其主要目的的潜力。它涉及一项基于模拟的研究，以评估用于互补实验的大厅中IFMIF-DONES的中性性能，这些实验可以运输中子。通过在这项工作中研究的简单梁管几何形状为4.5厘米的入口直径，我们表明，在大厅内提供了约2〜10 $^{10} $ 〜n/cm $^2 $/s的准确中性光束。在带有中子提取线的大厅中添加主持人将允许获得大约〜10 $^{6} $ -10 $^{7} $ 〜n/cm $ $^2 $/s的热中子梁，用于专用实验。结果表明，对于大多数中子应用，IFMIF-DONE的潜力是中型中子设施。
The IFMIF-DONES facility will be dedicated to the irradiation of structural materials planned for the use in future fusion reactors such as DEMO (Demonstration Fusion Power Plant). The potentialities of the IFMIF-DONES facility to complement its principal purpose by other experiments that would open the facility to other communities is addressed in this work. It concerns a study based on simulations to evaluate the neutronic performances of IFMIF-DONES in an hall dedicated to complementary experiments where neutrons can be transported. With the simple beam tube geometry of 4.5~cm entrance diameter studied in this work we have shown that a collimated fast-neutron beam of about 2~10$^{10}$~n/cm$^2$/s is available in the hall. Adding a moderator in the hall with neutron extraction lines would allow to get thermal neutron beams of about ~10$^{6}$-10$^{7}$~n/cm$^2$/s for dedicated experiments. The results show that IFMIF-DONES has the potentialities to be a medium-flux neutron facility for most of the neutron applications.
