Ion Coulomb crystals for precision spectroscopy and dynamical studies — •Heather L. Partner, Karsten Pyka, Jonas Keller, Tobias Burgermeister, and Tanja E. Mehlstäubler — Physikalisch-Technische Bundesanstalt, Braunschweig

We present our experimental setup, in which we trap and store Coulomb crystals of 172Yb+ and 115In+ ions. We provide technical details of the chip-based segmented linear Paul trap which we developed for metrological applications. It is specifically designed for minimizing excess micromotion, includes a protected spectroscopy segment and provides three dimensional laser access. This well-controlled environment allows to create and perform spectroscopy on 1D, 2D, and 3D Coulomb crystals. Using these crystals, we create topological defects and study the dynamics in laser cooled coupled ion systems.
