Two-species magneto-optical trap with 40K and 87Rb

open access: yes, 2001
We trap and cool a gas composed of 40K and 87Rb, using a two-species magneto-optical trap (MOT). This trap represents the first step towards cooling the Bose-Fermi mixture to quantum degeneracy.

Manufacturing a thin wire electrostatic trap (TWIST) for ultracold polar molecules

open access: yes, 2007
We present a detailed description on how to build a Thin WIre electroStatic Trap (TWIST) for ultracold polar molecules. It is the first design of an electrostatic trap that can be superimposed directly onto a magneto optical trap (MOT).
