Towards precision beta-decay measurements with laser cooled Ar-35

We present modeling and preliminary experimental results towards the development of our magneto- optical trap (MOT) setup and polarisation scheme for 35Ar. The atomic beam that is used for loading the MOT includes a novel transverse cooling arrangement based on a frequency broadened 'white-light molasses'. Our modeling shows that, under certain experimental conditions, such a setup can be beneficial in comparison to conventional transverse cooling techniques. We will report on experimental realization of such a setup.status: publishe
