Abstract In inertial confinement fusion (ICF), a fuel target containing deuterium and tritium is used. In recent ICF experiments on the Gekko XII LFEX facility at the Institute of Laser Engineering at Osaka University (ILE-Osaka), a target comprised of a polystyrene capsule filled with D2O liquid and a solution of X-ray tracer materials, such as copper, titanium, or chlorine, was developed. In this study, an additional T2O doping technique by which tritium can be mixed uniformly has been developed. The T2O is synthesized by T2 gas using a CuO oxidation catalyst. The T2O is agglutinated by cold trap and transferred to a target cell in which a D2O-solution-filled target is placed. Because polystyrene is slightly permeable for T2O and D2O, D2O is exchanged by T2O and completely mixed. Thus, a uniform tritium-doped ICF target with various materials can be fabricated. The T2O synthesizing and doping system is developed and tested using H2 as a cold run. The H2O is successfully doped to a D2O prefilled target at approximately 50% doping. This scheme will be utilized in future fast ignition experiments at ILE-Osaka.

在 Gekko XII-LFEX 设施开发用于惯性约束聚变的氚示踪剂掺杂液体燃料靶

摘要 在惯性约束聚变（ICF）中，使用含有氘和氚的燃料靶。最近在大阪大学激光工程研究所 (ILE-Osaka) 的 Gekko XII LFEX 设施上进行的 ICF 实验中，目标由充满 D2O 液体的聚苯乙烯胶囊和 X 射线示踪材料（例如铜）的溶液组成，钛或氯被开发出来。在这项研究中，开发了一种额外的 T2O 掺杂技术，通过该技术可以均匀混合氚。T2O 是由 T2 气体使用 CuO 氧化催化剂合成的。T2O 被冷阱凝集并转移到一个目标单元中，其中放置了一个充满 D2O 溶液的目标。由于聚苯乙烯对 T2O 和 D2O 具有轻微渗透性，因此 D2O 被 T2O 交换并完全混合。因此，可以制造具有各种材料的均匀掺氚的 ICF 靶。T2O 合成和掺杂系统是使用 H2 作为冷运行开发和测试的。H2O 以大约 50% 的掺杂成功掺杂到 D2O 预填充目标。该方案将用于未来 ILE-Osaka 的快速点火实验。
