An aluminum optical clock setup and its evaluation using Ca+

Abstract

This thesis reports about the progress of the aluminum ion clock that is set up at the German National Metrological Institute, Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig. All known relevant systematic frequency shifts are discussed. The systematic shifts were measured on the co-trapped logic ion 40Ca+, which is advantageous due to its higher sensitivity to external fields compared to 27Al+. The observation of the clock transition of 27Al+ and an analysis of the detection error is described.
