Segmented linear multi-ion traps for a next generation of transportable high-precision optical clocks — •Florian Köppen1, Hendrik Siebeneich1, Pedram Yaghoubi1, Michael Johanning1, Alexandre Didier2, Malte Brinkmann2, Stefan Brakhane3, Tanja Mehlstäubler2, Dieter Meschede3, and Christof Wunderlich1 — 1Naturwissenschaftlich-Technische Fakultät, Department Physik, Universität Siegen, Walter-Flex-Str. 3, 57072 Siegen, Germany — 2Physikalisch-Technische Bundesanstalt, Bundesallee 100, 38116 Braunschweig, Germany — 3Institut für Angewandte Physik der Universität Bonn, Wegelerstr. 8, 53115 Bonn, Germany
Trapped atomic ions are well suited for realizing accurate and stable optical clocks. The opticlock consortium [1] develops a compact transportable optical clock for non-specialist users, utilizing a quadrupole transition with a wavelength near 436 nm in a single 171Yb+ ion, with a projected uncertainty of order 10−16. Based on this system we develop a next-generation optical clock along [2] combining the accuracy of a multiple ion frequency standard with the compactness of the opticlock-demonstrator. For this purpose we use a segmented four layer ion trap and a compact vacuum interface, allowing for excellent optical access. We will present details of the chip carrier, chamber and cuvette, as well as the optical, electrical and software design.
