Abstract

We describe the experimental set-up used at LNE for closing the quantum metrological triangle (QMT) experiment and also testing the quantization of a current generated by a single electron device. Our present device is an R-electron pump composed of 3 tunnel junctions. The influence of the pumping frequency on the noise and on the current stability is firstly investigated. Then preliminary results are given about the quantized current measured with the complete QMT set-up. A relative random uncertainty of a few parts in 10⁶ has been found for a 100 MHz pumping frequency.
