Experimental Setup in the Niels Bohr Laboratory (image) University of Copenhagen Share Print E-Mail Caption The experimental setup in the laboratory. The atoms are captured in the magneto-optical trap in a vacuum chamber in the middle of the image using ultraviolet laser light (blue rays). The magnetic coils sit inside the chamber. The red laser light is used to transfer the atoms to the metastable state. Credit Niels Bohr Institute Usage Restrictions None.
