Twisted magnetic flux ropes show complex dynamic behaviour on different temporal and spacial scales. A prominent example for these confiugurations are arch-shaped solar prominences which can be stable for long periods before becoming eruptive. The FlareLab experiment is designed to investigate the evolution of expanding arch-shaped magnetic flux ropes. Recently, the experiment has been equipped with a new plasma source which provides more flexibility in the magnetic field configuration. It is aimed at following the model considerations proposed by Titov and Démoulin [1] as a descriptive model for a certain class of solar phenomena. First results obtained with the improved plasma source are presented in this contribution. Differences of the magnetic topology as compared to the previous plasma source design are shown and the corresponding influence on the discharge evolution is investigated.
