Development and Realisation of a Transportable Cold Atom Machine

NaKa’s o- and e-rack


Transportable cold atom experiments open up a new path for applications in e. g. geodesy, where the differential gravitational red shift can be measured by comparing two spatially separated atomic clocks. This thesis describes the design and set-up of a transportable cold atom experiment. Furthermore, the stability, performance and reliability of the electronical, optical and mechanical components before and after transport were investigated. The machine consists of two standardised 19-inch racks, where one is designated for electronical devices. The second one is home-built and features four retractable drawers for mounting optical elements, the λ = 767 nm laser and the vacuum system. After completing the full set-up at the University of Heidelberg, the experiment was partially disassembled, transported to and reassembled at a server room at the European Honda Research Institute in Offenbach (Main) within 20 hours. Controlling and observing the experiment fully remotely, we were able to achieve and characterise a two-dimensional magneto-optical trap for 39K atoms in both locations.
