  • Ultra-cold-matter system with thermally-isolated nested source cell
    Patent number: 9117563
    Abstract: In a disclosed embodiment, an ultra-cold-matter (UCM) system includes a source cell nested within a hermetically-sealed ultra-high-vacuum (UHV) enclosure. Source particles, e.g., strontium atoms, can be generated within the source cell by heating a non-vapor-phase source material. The source cell is thermally isolated, e.g., by UHV, from the enclosure. Accordingly, heat is retained in the source cell, reducing the amount of heat that must be generated in the source cell to generate the vapor-phase source particles. Particles can exit the source cell to an UHV ultra-cold region where the source particles can be cooled to produce ultra-cold particles thermally isolated from the heat within the source cell.
