20. A low-temperature high-precision heat transport measurement device comprising the probe system comprising a sample loader where a sample is loaded,
wherein the sample loader comprises a first frame comprising a sample loading space, and a second frame comprising an open end coupled to the first frame to accommodate the sample loading space, and
wherein the first frame comprises:
a sample supporter on which electrical terminals for conducting electricity from outside are provided;
a plurality of first support rods provided on a surface of the sample supporter to extend in a direction away from the surface, made of a thermal insulator, and coupled to support lines;
a plurality of second support rods provided on a surface of the sample supporter to extend in a direction away from the surface, made of a high thermal conductor, and capable of holding the sample;
thermometers and a heater suspended between the first support rods by the support lines;
electricity supply lines connected from the electrical terminals to the thermometers and the heater;
wherein the probe system further comprises:
a probe head;
a probe connector connected to an end of the probe head; and
a heat sink comprising an end connected to another end of the probe connector,
wherein the sample loader is connected to another end of the heat sink,
and wherein the probe system further comprises a plurality of SrTiO3 capacitance thermometers, and
wherein the plurality of SrTiO3 capacitance thermometers are connected to one capacitance measurement bridge through coaxial relays.
