We present the conceptual design of a polarized ${}^3$He target to be used for high luminosity scattering experiments within high magnetic field environments. This two-cell target will take advantage of advancements in optical pumping techniques at high magnetic field to create 60% longitudinally polarized ${}^3$He gas in a pumping cell within a uniform magnetic field above 1 T. By transferring the polarized gas to a cryogenic target cell, the gas density is increased to create a target thickness suitable for high luminosity applications. We discuss the general design of this scheme, and plans for its application in Jefferson Lab’s CLAS12 detector.

极化的概念 ${}^3$他的目标是在高磁场环境中进行高亮度散射实验

我们展示了极化的概念设计 ${}^3$他的目标是用于高磁场环境中的高亮度散射实验。这种双细胞目标将利用高磁场光泵浦技术的进步来产生 60% 的纵向极化${}^3$He 气体在高于 1 T的均匀磁场内的泵送单元中。通过将极化气体转移到低温目标单元，气体密度增加以创建适用于高亮度应用的目标厚度。我们讨论了该方案的总体设计，并计划将其应用于杰斐逊实验室的 CLAS12 探测器。
