Abstract

This research focuses on the development of a miniature ultrahigh vacuum system for cold-atom-based magnetometry. Comprised of a modular cold-atom source, and high quality optical cell in a double-MOT system, the approach primarily utilizes passive pumping technologies to facilitate sensitive magnetometry experiments with a cell volume less than 125 cm3. The source module will integrate all vacuum components necessary to prepare an alkali vapor and maintain ultrahigh vacuum. High quality cells will enable precise optical trapping, manipulation, and interrogation superior to conventional miniature cells. Further development will address handling of thermal alkali species while eliminating trace impurity gasses in their dispensing.
