Magnetic Ring Stores Cold Atoms

Facebook X LinkedIn Email
Researchers at Georgia Institute of Technology in Atlanta have demonstrated a magnetic storage ring for the control of 87Rb atoms. The device, called the Nevatron, may find application as an interferometric gyroscope for aircraft guidance or as a source for continuous-wave "atom lasers." The researchers guide clouds of 3-µK atoms from a magneto-optic trap to the ring using a pair of copper wires that are separated by 4 mm at the trap and by 840 µm at the storage ring. The 2-cm-diameter ring also comprises two wires, separated by 840 µm and carrying a current of 8 A. In the initial...Read full article
