A 3d micro-structured trap with low axial micromotion and high field gradients — •Delia Kaufmann, Timm F. Gloger, Peter Kaufmann, Michael Johanning, and Christof Wunderlich — Department Physik, Universität Siegen, 57068 Siegen, Germany

We present the status of a second generation 3d micro-structured segmented ion trap with built in solenoids for the creation of inhomogeneous magnetic fields. The new design is based on a trap, which, among other things, was used to demonstrate rf single ion addressing [1] and fault tolerant Hahn-Ramsey-spectroscopy [2]. To overcome the present limitations in terms of finite gradient size and axial micromotion and make it better suitable for the application of MAgnetic Gradient Induced Coupling (MAGIC) [3], and the formation of tailored entangled states [4], the new trap features a redesigned middle layer for lower axial micromotion and improved connectivity for higher solenoid current damage threshold. We discuss the design, simulations and the status of the experimental setup.
