Scientific News not always receive on-time recognition especially the ones coming from Japan.
Development of Voltage standards this is universal goal, and article below this is a proof of success which worth be shared and among ITTSB Blog readers.
The Quantum Electrical Standards Group of the Research Institute for Physical Measurement (Director: Yasuhiro Nakamura) of the National Institute of Advanced Industrial Science and Technology (AIST; President: Ryoji Chubachi), in collaboration with ADC Corporation (ADC; President: Hiroshi Mochida), has developed a compact direct current (DC) voltage standard with the world’s highest level of performance in temporal stability and temperature stability.
The developed DC voltage standard was achieved by employing a quantum standard for precise measurement of the voltage standard unit that serves as a reference standard and by utilizing circuit noise countermeasures, heat insulating packaging, and a modularization technology. High-precision voltage measurement becomes possible at R&D and quality management departments of manufacturers, universities, research institutions, and calibration facilities, and the efficiency of calibration operations is expected to improve dramatically.
