Apparatus for Cooling and Trapping Potassium Atoms

We describe our experimental apparatus for cooling and trapping potassium at Creighton University. There are three unique aspects of our experiment: a hybrid quadrupole/octupole 3D magneto-optical trap, a high-Q radio-frequency resonator to induce a Feshbach resonance, and a modified White and Scholten compact diffraction wavemeter for laser characterization.
