An advanced laboratory course based on the construction and modeling of a magneto-optic atom trap

Undergraduate physics labs often entail the collection of data using an apparatus that is set up and sometimes even fully adjusted before the students arrive. Various physical phenomena and data analysis techniques can be explored with this approach; however, students are unlikely to develop the experimental design and construction skills that are necessary for conducting original research. We present a magneto-optical atom trap designed and constructed for use in an undergraduate lab class that is organized to address the shortcomings of the more traditional approach. While the basic design and necessary equipment are made available, the students are required to build a working atom trap starting from an empty optics table. Additionally, students must model and simulate the operation of the trap to determine the necessary operating parameters and their tolerances. The results of these simulations provide a basis for interpretation of data collected from the operating trap.
