摘要：

This paper outlines the groundwork we have done in preparation for our proposed experiment to measure the electric dipole moment of the electron in barium monofluoride molecules within a cryogenic parahydrogen matrix. We describe the experimental setup we use to grow and characterize the cryogenic crystals and produce a molecular source of barium monofluoride. The technique we present has the potential to improve the sensitivity to the electric dipole moment of the electron by increasing the number of molecules under measurement without affecting their spin coherence times. If successful, this approach would represent a significant advancement in precision measurements using molecules in cryogenic solid matrices.
