Ultracold gases in optical lattices have turned out to be an excellent platform to study topological phenomena such as transitions between topological materials in particular in the presence of interactions. In [Gächter, Zhu et al., Science 2024] we found indications for topological edges which are purely induced by the presence of interactions. To improve access to the microscopics of such phenomena, we are currently building a fast parallelized quantum gas microscope for fermionic potassium and bosonic rubidium.  The main goals of the new apparatus are to have a fast experimental cycle time on the order of one second as well as to realize a new way of generating optical lattice potentials which promises unprecedented flexibility while retaining similar stability compared to traditional techniques.

We want to achieve the fast cycle time through a combination of big MOT-beams, strong magnetic gradients (1000 G/cm) for evaporation, fast imaging in the microscope through a novel accordion technique as well as parallelizing the experimental steps.

In this poster, I will present a progress report on the building as well as a detailed outlook on the future steps of this new experimental machine.
