Abstract :
We report on the progress achieved at PTB in setting up an experiment for the realization of a quantum capacitance standard based on the controlled charging of a capacitor by single electrons. An experiment of this kind was suggested and first performed by NIST. In order to enhance the accuracy of the experiment, we use a new kind of single-electron pump and a capacitor with improved design features. The main components for the experiment are presented and discussed.
