摘要

讨论了多步自旋转移极化技术中的退极化因素以及光泵极化氢离子源中最大极化的基本限制。详细研究了RHIC OPPIS的极化损耗,优化了光源参数,使OPPIS的极化率提高到86-90%。这使得AGS和RHIC的极化率增加了65 ~ 70%。

Towards 100% polarization in the optically-pumped polarized ion source
The depolarization factors in the multi-step spin-transfer polarization technique and basic limitations on maximum polarization in the OPPIS (Optically-Pumped Polarized H* Ion Source) are discussed. Detailed studies of polarization losses in the RHIC OPPIS and the source parameters optimization resulted in the OPPIS polarization increase to 86-90%. This contributed to increasing polarization in the AGS and RHIC to 65 ~ 70%.
