The opticlock consortium [1] will provide a demonstrator for a transportable optical frequency standard using laser cooled trapped ions. Clocks based on single trapped ions already provide excellent accuracy as optical frequency standards, which can be further improved by using multiple ions. Within opticlock, we already work on the next generation of the soon to be expected single-ion demonstrator by combining transportability with the low frequency uncertainties of a multi-ion frequency standard. A novel segmented four layer ion trap featuring low micromotion is combined with a dedicated compact vacuum interface, excellent optical access and customized vacuum setup. We will report on the overall design concept, the vacuum and optical layout, and the status of the setup.
[1] opticlock is supported by the bmbf under grant no. 13N14385.
