First 3D-trapped atoms! September 2014

This month our three-dimensional magneto-optical trap (3D MOT) went live with the installation of the last magnetic field compensation coils. This achievement is directly based on the recent realisation of a 2D MOT in our lab, which now loads the 3D MOT. At maximum our setup allows us to stabily trap about 5 billion atoms of Potassium 39. Eventually this reservoir will be used to load optical dipole traps.

The atoms levitated at the centre of our experimantal chamber fluores brightly in the image. Fascinatingly, the atom cloud can also easily be seen by the bare eye.
