Qualification of integration technologies for miniaturized op-tical setups in UHV — •Anne Stiekel1,2, Marc Christ1,2, and Markus Krutzik1,2 — 1Institut für Physik, Humboldt-Universität zu Berlin — 2Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik, Berlin
Development of compact atomic quantum sensors based on cold atoms enable novel applications (e.g. timekeeping, sensing and communications) in mobile devices and in space. Besides physics package and electronics, this also requires miniaturization of the optical distribution and beam manipulation systems. Precise alignment and micro-integration of the optical components is necessary for miniaturized and rugged optical setups, eventually being used within ultra-high vacuum (UHV) assemblies. Hence the used materials, components and integration technologies have to meet challenging demands regarding thermal and mechanical durability, as well as ultra-low out-gassing.
To qualify the UHV-compatibility, an adaptable system is being set up for residual gas analysis and measurement of total gas rates down to 5 · 10−10 mbar l s−1. This poster gives an overview on the UHV-system architecture and first results towards its commissioning.
