摘要

结果表明，使用无低温磁体可以消除冷头操作产生的时间磁场畸变，获得高质量的固态魔角自旋核磁共振结果。无低温磁体的紧凑设计允许探针从底部插入(如在大多数核磁共振系统中)，或者更方便地从顶部插入。磁场斜坡后，磁场沉降时间可短至一小时。因此，单个无低温磁体可以用于不同的固定场。磁场可以每天改变而不影响测量分辨率。

Cryogen-free 400 MHz (9.4 T) solid state MAS NMR system with liquid state NMR potential

We show that the temporal magnetic field distortion generated by the Cold Head operation can be removed and high quality Solid-State Magic Angle Spinning NMR results can be obtained with a cryogen-free magnet. The compact design of the cryogen-free magnets allows for the probe to be inserted either from the bottom (as in most NMR systems) or, more conveniently, from the top. The magnetic field settling time can be made as short as an hour after a field ramp. Therefore, a single cryogen-free magnet can be used at different fixed fields. The magnetic field can be changed every day without compromising the measurement resolution.
