Abstract

We present the design and operation of an ytterbium ion trap experiment with a setup offering versatile optical access and 90 electrical interconnects that can host advanced surface and multilayer ion trap chips mounted on chip carriers. We operate a macroscopic ion trap compatible with this chip carrier design and characterize its performance, demonstrating secular frequencies >1 MHz, and trap and cool nearly all of the stable isotopes, including ¹⁷¹Yb⁺ ions, as well as ion crystals. For this particular trap we measure the motional heating rate \ensuremath⟨\mathrmn\ifmmode \else \.\fi\ensuremath⟩ and observe an \ensuremath⟨\mathrmn\ifmmode \else \.\fi\ensuremath⟩\ensuremath∝1/\ensuremathω² behavior for different secular frequencies \ensuremathω. We also determine a spectral noise density S_E(1 MHz)=3.6(9)\ifmmode×\else\texttimes\fi10^\ensuremath-11 V² m^\ensuremath-2 Hz^\ensuremath-1 at an ion electrode spacing of 310(10) \ensuremathμm. We describe the experimental setup for trapping and cooling Yb⁺ ions and provide frequency measurements of the ²S_1/2\ensuremath↔²P_1/2 and ²D_3/2\ensuremath↔³D[3/2]_1/2 transitions for the stable ¹⁷⁰Yb⁺, ¹⁷¹Yb⁺, ¹⁷²Yb⁺, ¹⁷⁴Yb⁺, and ¹⁷⁶Yb⁺ isotopes which are more precise than previously published work.
