我们提出了在4.2 K的z轴0.866-T螺线管和x轴1.225-T偶极线圈，包括1.5-T/75-mm的室温孔魔角自旋核磁共振磁体在麻省理工学院弗朗西斯比特磁铁实验室开发的全电流测试结果。本文还介绍了将磁体组件浸入固体氮中以提高其热质量并在4.2-4.3 K温度范围内工作时磁体性能的结果。
We present results of full-current testing at 4.2 K of a z-axis 0.866-T solenoid and an x-axis 1.225-T dipole coil that comprise a 1.5-T/75-mm room temperature bore magic-angle-spinning nuclear magnetic resonance magnet developed at the MIT Francis Bitter Magnet Laboratory. Also included in the paper are results of the magnet performance when the magnet assembly is immersed, to enhance its thermal mass, in solid nitrogen, and operated in the temperature range of 4.2-4.3 K.
