Our magneto-optical trap allows the study of ultracold atoms.

The coldest atoms in Kansas can be found in our Magneto-Optical Trap (MOT).
Stuck in the "optical molasses" of six intersecting laser beams and the
field of a magnet, atoms can be cooled to just a fraction of a degree above
absolute zero. This greatly reduces the random thermal motions of the atoms
and makes it possible for us to study the details of collisions of ions with
these atoms to an unprecedented degree of precision.
The cold, trapped atoms can be probed with either laser light or slow ion beams.
These techniques are known as MOTRIMS, or magneto-optical trap recoil-ion momentum
"Team MOTRIMS" is headed by Professor
