Abstract
A temperature-control system for an NMR magnet system. A permanent magnet arrangement () with a central air gap () generates a homogeneous static magnetic field inside the air gap. A probehead () transmits RF pulses and receives RF signals from a test sample (). An H0 coil changes the amplitude of the static magnetic field. A shim system () in the air gap further homogenizes the magnetic field. A first insulation chamber () surrounds and thermally shields the permanent magnet arrangement and includes an arrangement () controlling a temperature T1 of the first insulation chamber. The shim system, the H0 coil and the NMR probehead are arranged outside the first insulation chamber in the air gap. A heat-conducting body () is arranged between the shim system and the H0 coil on one side and the permanent magnet arrangement on the other, thereby enhancing field stability and suppressing drift.
