Bon MOT: Innovative Atom Trap Catches Highly Magnetic Atoms (image) National Institute of Standards and Technology (NIST) Share Print E-Mail Caption Trapped erbium: Color-enhanced image of a cloud of erbium atoms trapped and cooled and a narrow-line MOT using a single laser beam. The laser beam is coming down from the top of the image, which measures about 1 millimeter square. The atoms collect along the ellipse of a constant magnetic field (dashed line) where they come into resonance with the laser. A faint cloud of residual, higher temperature atoms caught in the magnetic trap can be seen as well.
