Abstract :
This paper deals with the improvements of the experimental setup devoted to high-accuracy measuring of current across the single electron pump carried out at the BNM-LNE (formerly BNM-LCIE). Preliminary results of measurements of current voltage characteristics of the three-junction Cr-Al R-pump fabricated at PTB are given.
