Abstract:
As a joint project of the Quantum Electrical Metrology Section and the Thermometry Section of the National Metrology Institute of Japan, AIST, we have initiated a project on developing a system for the Johnson Noise Thermometry (JNT). This paper describes the objective, how we combine the technologies, the various phases of the projected plan for the system development, as well as the results of the of the project up to the present.
