Abstract

In the Bachelor thesis electrostatic hexapoles and quadrupoles are investigated by simulations done in Python. These hexapoles or/and quadrupoles had the goal to increase the number of accepted molecules in a Stark decelerator. This Stark decelerator is part of a bigger project. In this project the electron electric dipole moment will be measured for Barium Mono-Fluoride molecules. These simulations were done for all the practical problems the project has between the cryogenic source and the Stark decelerator. These problems mostly come from the transversal and longitudinal velocities of the molecules leaving the source. The highest achieved acceptance for this research is found when there are two guides placed. The front guide has to be a 125 mm hexapole of 4 mm inner radius at applied voltage of 6.5 kV. And the rear guide has to be a 50 cm hexapole of 4 mm inner radius at applied voltage of 6.9 kV. In Figure 29 this situation is displayed. For future research, this same simulation code is accessible for the NL-eEDM team.
