A long-distance delivery system for laser-polarized 129 Xe that uses a capillary tube is described. To our knowledge, this is a first nuclear magnetic resonance (NMR) study of laser-polarized 129 Xe fluid behavior that focuses on the effects of the length and inner diameter of the delivery tube of the system. It is found that the maximum signal intensity of laser-polarized 129 Xe in a laminar flow is hardly affected by depolarization, even when a tube with a length of 10 m is used under continuous flow conditions. The sensitivity of Xe to its local magnetic environment was successfully applied to demonstrate the usefulness of fused silica capillary tubes with inner diameters ≤0.53 mm. Extensions of this technique should enable the more efficient delivery of 129 Xe gas with the sustainable polarization of laser-polarized 129 Xe.

使用毛细管长距离传输激光偏振129 Xe

描述了一种使用毛细管的用于激光偏振129 Xe的长距离传输系统。据我们所知，这是对激光偏振129 Xe流体行为的首次核磁共振（NMR）研究，重点研究系统输送管的长度和内径的影响。发现即使在连续流动条件下使用长度为10 m的管时，层流中激光偏振129 Xe的最大信号强度也几乎不受去极化的影响。Xe对其局部磁性环境的敏感性已成功应用于证明内径≤0.53mm的熔融石英毛细管的有用性。这项技术的扩展应该能够使129 Xe气体更有效地传输，并且激光偏振129 Xe具有可持续的极化能力。
