Moving Magnetic Trap

Supersonic beams generate ensembles of cold and very fast paramagnetic atoms or molecules.

We can load them in a 3D moving magnetic trap and bring them to rest in the laboratory frame of references without losses!



Enables preparation of pure atomic beams with a narrow velocity distribution. Atomic beams such as O, N, H, D, He, Ne, are important in low temperature interstellar chemistry whereas atomic beams of Ni, Fe, Cr and other elements might find technological applications.
