DEVICE TO MEASURE TEMPERATURE PARAMETERS OF SUPERCONDUCTORS

摘要

FIELD: measurement equipment.SUBSTANCE: invention relates to devices for investigation of superconductors with the help of electric and magnetic means. Two inductance coils are installed in the device body. Axes of coils are aligned in parallel to each other and the surface of the sample placed between the coils. To reduce scattering field of the primary coil and to increase the value of signal fall during transition into superconducting condition, the inductance coils are made with a rectangular cross section and installed with a smaller side of a rectangle in parallel to the sample surface. A mechanism to adjust and fix the distance between the sample and the surface of the cryoagent provides for elimination of impact of convection vapours near the cryoagent surface. The device body is made of two halves. The sample of the superconductor is installed in the plane of the body joint to ensure accurate fixation of superconductor position relative to inductance coils and cryoagent surface.EFFECT: invention makes it possible to ensure high accuracy of measurement of temperature parameters of superconductors.5 cl, 5 dwg
