DEVICE FOR THERMOSTATTING A SAMPLE IN MAGNETIC RESONANCE SENSOR Russian patent published in 2008 - IPC G01N24/08 G01R33/20 

FIELD: resonance radio-spectroscopy, possible use for managing and maintaining given temperature in volume of sample being examined, in particular in experiment of measurement of magnetic relaxation using nuclear magnetic resonance method.

SUBSTANCE: device for thermostatting a sample in magnetic resonance sensor contains receiving-transmitting coil, which forms the thermostatted volume, temperature sensor, connected to input of temperature control block, to output of which heating element is connected, where receiving-transmitting coil is wound on heat-isolating frame, inside which heating element is positioned, and temperature sensor is positioned directly on heating element. As heating element, hollow metallic cylinder is used with through longitudinal cut, or heat-emitting cover of thermo-resist, applied onto internal surface of heat-isolating frame and having longitudinal track 2 mm wide without cover for removing vortex current, or a coil of bifilar wire. Hollow metallic cylinder has cuts for creation of heating current channels, starting alternately at upper and lower ends of cylinder and not reaching the opposite end for distance, which approximately equals the distance between opposite cuts. Metallic cylinder may protrude beyond the limits of polar tips of magnets.

EFFECT: reduced gradient of temperatures in volumetric sample, reduced time of reaching the thermostatting mode and decreased level of electromagnetic interferences.
