Outline of Final Research Achievements

We have been developing a Johnson noise thermometry system using quantum voltage noise source toward redefinition of the Boltzmann constant k. Johnson noise thermometry is based on Johnson-Nyquist Equation. Power spectrum density of a sensor resistor is measured with respect to power spectrum density of the quantum voltage noise source. The noise power of the quantum voltage noise source is expressed in terms of the Planck constant h, electric charge e, sampling frequency of a pulse pattern generator f, and a given numerical factor. k obtained in our measurements has offset of +(40±20) ppm form the CODATA value. In order to contribute to redefinition of the Boltzmann constant, it is necessary to overcome this offset problem and reduce the uncertainty 1/20 times smaller than the current value.
