Design and Analysis of the Novel Test Tube Magnet for Portable NMR Device
The paper presents a novel test tube magnet (TTM) for Portable NMR device, which is composed of a dipole cylinder magnet and a hemi-cylinder or a hemi-sphere magnet. The hemi-cylinder or the hemi-sphere magnet is attached to one end of the dipole cylinder magnet, so that the whole magnet is shaped like a test tube. TTM generates a wide diameter spherical volume (DSV) with a high magnetic field homogeneity, which makes the device more applicable for portable NMR. The two configurations were simulated with three-dimensional finite-element methods. Flux density elements are effectively corrected in the DSV. The homogeneity increases, the magnet volumes and mass are markedly decreased, and the construction is very reasonable. Taken together the new designs have improved characteristics for portable NMR.
