Over 200 physicists and engineers from Asia, Europe and
the Americas, including 21 people from SLAC, met at the KEK High Energy
Physics Laboratory in Tsukuba, Japan, to explore rapid development of a
conceptual design of the International Linear Collider (ILC).

Originally conceived as a meeting for some 30 people, the
organizers were overwhelmed with requests to participate. The enthusiasm
for this new project was clear throughout the meeting.
"KEK has been delighted to host this important workshop,"
KEK’s Director General Yoji Totsuka said. "For the first time the world’s
linear collider community is working together to start discussions on a
final design for the ILC. We have provided opportunities for accelerator
experts from various regions, who may have previously been working on
different projects, to get to know each other and start the important
process of creating a unified team."
"Last August, the international particle physics community
made a difficult but necessary decision in choosing
superconducting-technology for the accelerating system of the ILC. Cornell
University’s Maury Tigner, chair of the International Linear Collider
Steering Committee, said, "The decision opened the way for the world
particle physics community to unite and concentrate our combined resources
behind one technology. There is a long way to go and much hard work needed
before the final design of the ILC is established. However, the first
steps on a journey can sometimes be the hardest. The success of the KEK
ILC workshop has set us off in the right direction."
Working groups at the meeting focused on many aspects of
the future design of the accelerator including; the parameters of the main
linacs, the injector system, the beam delivery system, the design of the
high gradient radio-frequency cavities and how to effectively communicate
both within the ILC community and to the public. SLAC was represented in
all working groups.
"It has been a very stimulating meeting," said Tor
Raubenheimer, head of the SLAC’s Linear Collider Department. "Since the
technology decision is made, people will no longer be working with
opposite goals or different goals. We’ll be working towards a common goal
and that makes it very exciting."
