Publicación Sólo datos Cryogenic buffer gas beam source design for laser cooling radioactive molecules(Universidad EIA, 2025) Muñoz Arias, Samuel; Rodríguez Fernández, JohnnatanABSTRACT: This thesis presents the design of a cryogenic buffer gas beam source with the scientific goal of applying laser cooling techniques to radioactive molecules. Laser cooling enables controlled manipulation of molecules, making it a valuable tool for precision measurement experiments with radioactive species. Particularly, radium-containing molecules that exhibit octupole-deformed nuclei offer a unique opportunity to explore physics beyond the Standard Model (Garcia Ruiz et al., 2020). Despite the interest in the study of these molecules, the production of cold and slow molecular beams presents significant challenges due to the cryogenic conditions required. This foundational work will establish the experimental basis for laser cooling of radium-containing molecules, enabling subsequent experiments that could provide the opportunity to study some of the main open questions in our understanding of the universe. The project will combine both quantitative and qualitative approaches. Data collected through simulations, analytical calculations, expert insights, and reference designs will guide each stage of development. Key objectives include determining suitable materials for cryogenic operation, developing a high vacuum chamber to sustain low pressures, analyzing thermal conductance inside the beam source and integrating a real-time temperature monitoring system.
