T1 CONTROL AND STABILIZATION OF TEMPERATURE (0.8÷300 K) IN THE CRYODIELECTROMETER OF A GIGAHERTZ FREQUENCY BAND JF Telecommunications and Radio Engineering JO TRE YR 2014 FD 2014-08-01 VO 73 IS 11 SP 993 OP 1003 K1 radiospectroscopy K1 dielectrometry K1 low temperatures K1 thermometry AB A problem of accurate temperature stabilization and measurement arises during the development of low-temperature radiospectrometers designed for material dielectric parameter measurement in the millimeter waveband and in the wide temperature range. Thermometers used for measurement of low and ultra-low temperatures are usually based on the temperature dependence of particular material properties. Electric resistance thermometers are the most suitable for designing the circuits for temperature measurement and stabilization under the above-mentioned conditions. The temperature controller-stabilizer, being a precise automated block, designed for measurement and stabilization of temperature of the disk dielectric resonator in the 0.8 K÷300 K temperature range is used in the cryodielectrometer of a gigahertz band. The four-wire circuit with alternating-current supply to the thermal sensors is applied. The specialized resistive sensors with different-sign temperature resistance coefficients are tested. The accuracy of resistance detection of about 0.05% is provided. The accuracy of temperature stabilization is higher than ±0.01 K. Results of test experiments on the measurement of low-loss dielectric material parameters at low temperatures are presented.
