固相中高极化的氢分子是核物理实验中的“极化靶”和惯性约束聚变(ICF)中的极化燃料。在法国-意大利Graal的合作下，我们正在建造一个新的极化高清目标工厂，植入IPN Orsay。它包括一个强大的稀释冰箱(10 mK时12μW)，配备16.5T超导磁体和几个辅助的低温恒温器，用于冷凝、存储、转移和运输极化的HD样品。主要目标是生产偏振高清目标(HYDILE项目)，用于光生实验，使用Graal偏振高能真实光子束，从激光对格勒诺布尔ESRF环中存储的电子的后向散射获得。其他地点的靶子的生产是可以预见的。文中将描述该系统，并给出已获得的HD样品静态极化的结果。讨论了研究HD的动态极化方法并将其应用于DT以生产用于聚变的极化DT燃料的可能性。
Highly polarized hydrogen molecules in the solid phase are of primary interest as “polarized targets” for Nuclear Physics experiments and polarized fuel for Inertial Confinement Fusion (ICF). Within the French–Italian GRAAL collaboration, we are constructing a new Polarized HD Target Factory, implanted at IPN Orsay. It consists of a powerful Dilution Refrigerator (12μW at 10mK) equipped with a 16.5T superconducting magnet and several ancillary cryostats for condensation, storage, transfer and transport of polarized HD samples. The primary objective is to produce polarized HD targets (HYDILE project) for the photoproduction experiments with the GRAAL polarized high energy real photon beams, obtained from backscattering of laser light against the electron stored in the ESRF ring at Grenoble. Production of targets for other sites is forseen. The system will be described and the results already obtained for the static polarization of a HD sample will be given. The possibility to investigate dynamic polarization methods for HD and apply them to DT in order to produce polarized DT fuel for fusion will be discussed.
