Abstract
QUANTUS-2 is a mobile high-flux rubidium BEC source used for experiments in microgravity in the drop tower in Bremen. To further decrease the expansion rate of the BEC, magnetic lensing - also known as delta-kick collimation - is crucial for observations after long evolution times in the range of seconds. Long evolution times are desirable, because the sensitivity of atom interferometers enhances quadratically with the interrogation time. An observability of the BEC of up to 2.0 s after free expansion was demonstrated. We present new analysis methods and results from simulations to increase our understanding of the used magnetic lens.
