Patent number: 9960025Abstract: A cold-atom cell is formed by machining a block of silicon to define sites for an atom source chamber, an atom manipulation chamber, and an ion-pump chamber. A polished silicon panel is frit-bonded to an unpolished (due to machining) chamber wall (which would be difficult and costly to polish). The polished panel can then serve as a reflector or a sight for anodic bonding. A solid-phase atom source provides for vapor phase atoms in the source chamber. The source chamber also includes carbon and gold to regulate the atom pressure by sorbing and desorbing thermal atoms. The atom manipulation chamber includes components for magneto-optical trap and an atom chip, e.g., for forming a Bose-Einstein condensate. The ion-pump chamber serves as the site for an ion pump. By integrating the ion pump into the body of the cold-atom cell, a more compact, reliable, and robust cold-atom cell is achieved.Type: GrantFiled: November 11, 2014Date of Patent: May 1, 2018Assignee: ColdQuanta Inc.Inventor: Steven Michael Hughes
