Mr Yuan with the BIPM Josephson Voltage Standard system.

Mr Yuan Gao, National Institute of Metrology (NIM), China, started his five month secondment in the BIPM Physical Metrology Department on 4 January 2016.

He will be working on the macroscopic quantum electrical standard for the measurement of the coil current of the BIPM watt balance. His work focuses on the metrological characterization and the validation of a measurement system including a programmable Josephson Voltage Standard (JVS) and a high-precision digital voltmeter.
