May 9, 2005 - More than 1,200 national and international accelerator scientists and engineers will convene at the Knoxville Convention Center (KCC) May 16-20, 2005, for the 21st biennial Particle Accelerator Conference (PAC05). The world's largest conference of its kind will cover cutting edge developments in all aspects of the science, technology, and specifically the use of particle accelerators.

Topics of interest at this year's conference revolve around the "World Year of Physics," a special title declared by the United Nations marking the 100th anniversary of Albert Einstein's "miraculous year" of 1905, when he published three papers that revolutionized the physical sciences.

Tennessee Gov. Phil Bredesen, a physics graduate of Harvard University, will welcome the conference attendees on May 16. Cecilia Jarlskog of Lund University, a member of the Nobel Prize committee, will describe in the opening remarks how Einstein won the Nobel Prize for Physics in 1921.

An "Einstein and the World Year of Physics" special session on May 18 will feature talks by Nobel Laureate Carlo Rubbia and the National Science Foundation's Michael Turner. Also on May 18, local physical science teachers will have the opportunity to learn more about particle accelerators and Einstein's discoveries during "Teacher's Day." Finally, the day's events will culminate with the "Einstein-in-the-City" celebration, beginning at 6:00 pm in the World's Fair Park. This event will be an opportunity for the public to celebrate and learn more about Einstein's legacy alongside the conference attendees. Planned for the "Einstein-in-the-City" celebration is a science fair for local high school students from Roane, Anderson, Knox and Blount counties, live demonstrations, children's activities, a science discussion chaired by Dr. Bill Madia, former director of ORNL, food and drinks from local restaurants as well as live entertainment.

The PAC05 is organized under the joint auspices of the Institute of Electrical and Electronics Engineers (IEEE), through its Nuclear and Plasma Sciences Society (NPSS), and the American Physical Society (APS), through its Division of Physics of Beams (DPB). The conference series, which began in 1965, also serves as the annual meeting of the DPB and is supported in part by the U.S. Department of Energy and the National Science Foundation. Additionally, Oak Ridge National Laboratory's (ORNL) Spallation Neutron Source (SNS) and the Thomas Jefferson National Accelerator Facility are the hosting organizations of the PAC05.

Approximately 120 industrial exhibitors from 60 international companies are expected to attend the conference. These vendors will represent companies that have commercial interests in particle accelerator components, accelerator construction and related technologies. A special vendor reception hosted by Knoxville and Oak Ridge community and economic development leaders will be held at 5:30 p.m. May 16 at the Knoxville Museum of Art.

Previous PACs were held in San Francisco, Dallas, Vancouver, New York, Chicago and Portland (OR). While 50% of conference attendees hail from the United States, 25% come from Europe and the Commonwealth of Independent States (former Soviet Union) and 25% from come from Asia. All attendees will stay in downtown Knoxville hotels during the five day conference with many arriving earlier or remaining after the conference to take advantage of customized tours of the local attractions. The tours were developed by the Knoxville Tourism & Sports Corporation (KTSC).

The conference chair is Dr. Norbert Holtkamp of ORNL's SNS. The PAC05 Scientific Program Committee, chaired by Swapan Chattopadhyay of Jefferson Lab, has arranged the scientific program of the conference. The program, publication instructions, and all other relevant information are available on the conference web site at www.sns.gov/pac05. The head of the Local Organizing Committee is Stuart Henderson of ORNL/SNS.

Accelerators are large science instruments that are used as microscopes. Charged particles, heavy or light, are accelerated in order to probe the constitution of matter directly by having them hit other matter, or indirectly by creating very intense light that is then used to shine on matter. All around the world, particle accelerators are used for different applications of this principle and help to resolve puzzles in astrophysics, physics, engineering, material research and biology. Some smaller scale industrial applications exist in areas of homeland security, food irradiation, cancer therapy and inspection.

The KTSC projects that the PAC05 will have a local economic impact of $2,208,000.
