Design of A Magnet with Constant gradient field for Nuclear Magnetic Resonance

The principle of constant gradient field NMR is same with the logging expert system, the state-of-the -art technology in the world, wherein, gradient design and 2D spectrum inversion algorithm are adopted to quicken the instrument measurement speed while the diffusion coefficients of a fluid can be measured and the information obtained via the measurement of instrument can be more complete and authentic. The Article mainly introduces a magnet for gradient constant field NMR from such aspects as the parameter calculation of the gradient field, the selection of magnetic materials, finite element calculation and analysis, and detector installation and debugging. Experimental data shows that the design can completely realize fast NMR inspection and 2D spectrum inversion.
