Quantum bubbles atoms confined to a closed surface offer a unique platform for studying topological phenomena, including vortex dynamics and collective modes on curved manifolds. Creating these potentials requires RF-dressed states, where the direct interaction between atoms and the RF field makes the system highly sensitive to source noise. The Quantumania project targets these geometries using the MAIUS-1 payload in the Einstein-Elevator at Leibniz University Hannover. To ensure sufficient field quality, we have initiated the design of a custom RF source specifically to minimize heating and noise. We present the technical specifications of this new source and our strategy for antenna optimization. These efforts aim to achieve robust atom dressing in the Einstein-Elevator. Furthermore, characterizing these bubble potentials contributes to the optimization of experimental schemes within our collaboration with the Cold Atom Laboratory on the International Space Station.
