We study structural defects (kinks) in Coulomb crystals of Mg-Ions in dependency on the ratio of radial to axial confinement and cooling conditions [1].
The formation of kink configurations and the transformation of kinks to different structures are investigated. We compare the properties of extended (2D) and blurred (3D) kinks for crystals consisting of 30 ions [2]. Furthermore, different creation and control processes are studied in detail.
