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
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
