DEVICE FOR STABILIZATION OF TEMPERATURE OF SAMPLE IN MAGNETIC RESONANCE SPECTROMETER Russian patent published in 1998 - IPC

FIELD: magnetic resonance spectral measurements, in particular, for experiments which measure time of magnetic relaxation and coefficients of self-diffusion using nuclear-magnetic resonance methods. SUBSTANCE: device has transceiver coil and coil of magnetic field gradient in frame. Said coils border thermostatic chamber. In addition device has temperature detector, which is connected to temperature control unit, and heating element. Goal of invention is achieved by introduced two temperature detectors, heating element, temperature gradient control unit and unit which switches direction of heat carrier flow. EFFECT: active control of temperature and keeping constant temperature gradient for given temperature. 2 dwg
