最近，人们越来越关注将灵敏的 fl 衰变不对称检测核磁共振 (fl-NMR) 技术应用于生物学研究。 ISOLDE 建立了液体样品 fl-NMR 装置，以进行此类研究并在核物理中使用液态 NMR 的分辨率增益。作为该装置的一部分，开发了磁场锁定系统、一组印刷电路板匀场线圈、一个样品交换系统、一组紧凑型荧光探测器和一个定制实验真空室。通过锁定系统将主磁场稳定至 ppm 级，同时允许直接确定绝对磁场。磁场均匀性改善为
Recently there has been an increased interest to apply the sensitive fl-decay asymmetry detected nuclear magnetic resonance (fl-NMR) technique to biological studies. A liquid-sample fl-NMR setup was build at ISOLDE to allow such investigations and to use the resolution gain of liquid-state NMR in nuclear physics. As part of this setup a magnetic field locking system, a set of printed circuit board shimming coils, a sample exchange system, a set of compact fl-detectors and a custom experimental vacuum chamber were developed. The main magnetic field was stabilized down to the ppm level by the locking system while allowing the direct determination of the absolute magnetic field. The homogeneity of the magnetic field was improved to
