  • Magneto-optical trap ion source
    Patent number: 7709807
    Abstract: A system and method are disclosed for producing a source of ions, and particularly, a focused ion beam. The system and method use a magneto-optical trap (MOT) to produce a population of neutral atoms. A laser is then utilized to ionize atoms and produce a population of ions. An extraction element is then used to transfer the ions so that they can be used in a wide array of applications.
    Type: Grant
    Filed: May 7, 2008
    Date of Patent: May 4, 2010
    Assignee: United States of America as represented by the Secretary of Commerce, The National Institute of Standards and Technology
    Inventors: Jabez J. McClelland, James L. Hanssen, Marcus Jacka, Shannon B. Hill
