Six Argonne scientists inducted into American Physical Society

ARGONNE, Ill. — Six scientists from the U.S. Department of Energy’s Argonne National Laboratory were recently elected fellows of the American Physical Society (APS) for 2010. Argonne’s contingent of new fellows for this year is larger than that of any other laboratory, university or corporation in the world.

“We take great pride in the honor bestowed upon these Argonne scientists by the APS, the primary professional association of physicists in the United States,” said Argonne director Eric Isaacs. “That so many of our scientists and engineers would be named fellows in a single year is a testament to the vision and talents of the laboratory’s researchers and the importance of the work they are doing.”

Argonne accelerator physicist Wei Gai, chemist Julius Jellinek, X-ray scientists George Srajer and Jin Wang and particle physicists Rikutaro Yoshida and Cosmas Zachos were inducted for a wide range of different research that spans a wide gamut of fundamental chemistry and physics research.

Gai earned election to the APS for pioneering an alternative form of acceleration of particle beams, known as wakefield acceleration, which enables scientists to create great energy densities in small accelerators.

Srajer and Wang were both recognized for their contributions to condensed matter physics. Srajer’s work focused on applying the synchrotron radiation generated by Argonne’s Advanced Photon Source to examine phase transitions and magnetic properties of different crystalline structures. Similarly, Wang used high-energy X-rays generated by the Advanced Photon Source to characterize nanoparticle thin films and the dynamics of liquid sprays, like those from fuel injectors in cars.

The careers of Yoshida and Zachos have focused more heavily on theoretical and fundamental science. Yoshida helped to develop and manage the ZEUS detector, a particle detector based at a collider in Hamburg, Germany while Zachos pioneered the field of supersymmetry, which tries to relate different elementary particles to each other to create a unifying physical model.

Finally, Jellinek was inducted for his contributions to simulations of nanoscale systems.  In his career at Argonne, Jellinek led research into a wide range of properties for atomic and molecular clusters.

The American Physical Society ( is the leading physics organization, representing 48,000 members, including physicists in academia, national laboratories, and industry in the United States and internationally. APS has offices in College Park, MD (Headquarters), Ridge, NY, and Washington, DC.
