چکیده

A new measurement set-up for calibration of secondary DC voltage standards at the level of 1.018 V has been developed by the Bureau International des Poids et Mesures (BIPM). A metrological validation process was developed to ensure the correct operation of the new set-up and to demonstrate its consistency with the previous set-up. Firstly, a direct comparison of two primary voltage standards shows that the voltage references are equivalent within their stated uncertainties. Secondly, two different methods were applied to compare the calibration results of five different Zener voltage standards obtained with the old and the new set-up. All the results converge and confirm that the new automated measurement set-up is ready for operation. The new set-up is consistent with the previous system and metrological traceability to the previous Josephson voltage standard (JVS) is guaranteed.

Comparison of the Josephson Voltage Standards of the PTB and the BIPM

A comparison of the Josephson array voltage standards of the Bureau International des Poids et Mesures (BIPM) and the Physikalisch-Technische Bundesanstalt (PTB), Braunschweig, Germany, was carried out in October 2014 at the level of 10 V. For this exercise, options A and B of the BIPM.EM-K10.b comparison protocol were applied. Option B required the BIPM to provide a reference voltage for measu...

Comparison of the NIST and BIPM Air-Kerma Standards for Measurements in the Low-Energy X-Ray Range

. A direct comparison was made between the air-kerma standards used for the measurement of low-energy x rays at the National Institute of Standards and Technology (NIST) and the Bureau International des Poids et Mesures (BIPM). The comparison was carried out at the BIPM using the BIPM reference beam qualities in the range from 10 kV to 100 kV. The results show the standards to be in agreement t...

Rapport BIPM-2001/01: Instructions for ac measurements of gated QHE devices

The BIPM has developed a method using back-gates to optimize the ac behaviour of quantum Hall effect (QHE) devices. Using this method one can obtain a quantized Hall resistance featuring a low frequency coefficient, of the order of 1 to 2 parts in 10 per kHz, useful for capacitance and impedance metrology [1]. This report gives instructions for implementing the method. Although the method is ge...
