abstract: This thesis describes the ongoing construction of an ultra-cold atomic
mixture experiment using sodium (23Na) and potassium (39K). The
planned experimental setup consists of a two-dimensional trap geometry with a high-resolution imaging system for observing the atoms.
This new setup aims to provide a robust and stable mixture experiment, ensuring as much flexibility and independence of the two species
as possible.
In this experiment, sodium atoms have been cooled to degeneracy, and
Feshbach resonance measurements of thermal potassium in the optical
dipole trap have been conducted [1]. The achievement of a dual-species
degeneracy has been impeded by considerable three-body losses between sodium and potassium to date.
This thesis describes the experimental setup, focusing on the vacuum
system and the two-dimensional magneto-optical trap, and provides a
critical discussion of these components. These components influence the
efficient loading of atoms into the subsequent stages of the experiment.
In addition, this thesis describes the design and optical characterisation of the two-dimensional optical dipole trap and the vertical high
numerical aperture imaging system. Both are important steps towards
the two-dimensional geometry of the system and the first experiments
after achieving the dual species condensate.
