Abstract

In this report the goal is to find a way to improve the light collection at the experiment concerning the electron electronic dipole moment (eEDM). The main signal in this atomic physics experiment is based on resonant photon scattering of several optical transitions in the barium monofluoride (BaF) molecule. Improving the light collection has been done by designing a light collection system which fits the spatial requirements of the already existing part of the experiment. The light collection is quantified with a Thorlabs’ FDS1010 photodiode as a detector and an LED as a light source. An important aspect is that the fluorescence light of the BaF-EDM experiment is not originating from a single point, but from an extended region of about 1 cm3. Therefore, the designed system has been tested for a number of geometries. By doing this, the light collection has been fully characterized with respect to the volume of the light source. The improvement has been determined reading up to 340 ± 10 times more than without the light collection system.
