External RBS analysis setup at U niversity of G öttingen: RBS analysis for liquid samples

Abstract

In this work, we describe new developments in the external analysis setup at University of Göttingen. The aim of this work is to expand the ability of the setup for performing Rutherford backscattering spectrometry (RBS) in atmospheric condition. This work presents the detail of the developed device for external RBS, as well as the initial result of RBS analysis for a volatile liquid sample. We also made an electrochemical cell with a Si 3 N 4 window designed for external RBS analysis. By using this setup, we have successfully acquired the change of composition around an electrode/liquid electrolyte interface. Since RBS can give us quantitative depth information, the external RBS developed here will open a way to characterize a solid‐liquid interface quantitatively and understand the chemical reaction of the interface.
