Permanent magnet assembly for an NMR system with a device for supporting and adjusting the permanent magnets

摘要

The device has a first rigid fork (10) of non-magnetic material that clamps the individual permanent magnet (30) laterally in fixed manner. A second rigid fork of non-magnetic material engages first rigid fork through slide-way system oriented along radial direction. The first rigid fork is adjusted radially relative to stationary support (40) to which second rigid fork is attached. The second rigid fork is provided with adjustment portion (24) to adjust the position relative to the stationary support in a direction perpendicular to the main faces of permanent magnet. Independent claims are included for the following: (1) a magnetized structure applied to nuclear magnetic resonance apparatus; and (2) a method of creating a main magnetic field of a spectroscopy.
