提出了一种基于强磁场光泵作用下低能~ 3 He ~+离子与极化碱金属原子（Rb）的自旋交换碰撞的极化~ 3 He离子源。为了将~ 3 He ~+离子的电子极化转移到~ 3 He核，我们提出了基于非绝热跃迁方法的索纳跃迁。为了有效地将3 He+离子电离成3 He 2+离子，在加速3 He+离子后，用气体/箔剥离器剥离3 He+离子。作为极化~ 3 He ~+离子的小型电离器，还提出了一种强磁场工作的EBIS（电子束离子源）电离器。
A proposal is presented on the polarized3He ion source based on the spin-exchange collisions of the low-energy3He+ion with polarized alkali-metal atoms (Rb) which are optically pumped under the strong magnetic field. To transfer the electron polarization of3He+ion to the3He nucleus, we offer to use the Sona transition based on a non-adiabatic transition method. For efficiently ionizing3He+ion to form3He2+ion,3He+ion is stripped with a gas/foil stripper after accelerating3He+. As a compact ionizer for polarized3He+ions, an EBIS (Electron Beam Ion Source) ionizer operated with a high magnetic field is also proposed.
