International Panel Recommends "Cold" Technology for Future Particle Accelerator Beijing, China—The International Committee for Future Accelerators (ICFA), meeting during an international physics conference here, today (August 20) endorsed the recommendation of a panel of physicists charged to recommend the technology choice for a proposed future international particle accelerator.
"Both the 'warm' X-band technology and the 'cold' superconducting technology
would work for a linear collider," the ITRP’s Barish said. "Each offers its
own advantages, and each represents many years of R&D by teams of extremely
talented and dedicated scientists and engineers. At this stage it would be too
costly and time consuming to develop both technologies toward construction. The
panel had our first meeting in January 2004 and started our evaluation of the two
technologies. The decision was not an easy one, because both technologies were well
advanced and we knew the selection would have significant consequences for the
participating laboratories. On the basis of our assessment, we recommended that
the linear collider design be based on the superconducting technology."

Fermilab Prepares to Follow ILC Decision Fermilab is now preparing to commit its own efforts in "cold" or superconducting technology in line with the endorsement of the International Linear Collider Steering Committee and the International Committee for Future Accelerators. "The technology decision is a big step towards the ultimate goal, which is the construction and operation of a linear collider," said Steve Holmes, Associate
Holmes, also a member of the American Linear Collider Steering Committee, continued: "This decision will allow a consolidation of resources, both at Fermilab and within the world community, in pursuit of that goal." Shekhar Mishra, Head of Fermilab's ILC efforts, added: "Physicists from around the world have yet again shown that we can make a tough choice. There is still a tough road ahead on the ILC. Fermilab will work with SLAC, KEK, DESY and other institutions around the world to make the ILC a truly international project." Fermilab has contributed to research and development in both warm and cold technology ("Linear Collider R&D at Fermilab," Fermilab Today, Friday, July 16, 2004).
Concluded Holmes: "We will be working hard over the next several weeks to meet
the challenge of organizing ourselves and working with collaborators throughout
the world to establish an effective global design effort aimed at a superconducting
linear collider."

From the Stanford Report, August 18, 2004 Task force tackles role of particle physics in universe Deciphering the laws govering dark matter and dark energy by Davide Castelvecchi
A string of recent discoveries in astronomy has left scientists with an unsettling realization: The stuff we know and understand makes up less than 5 percent of the universe. The rest has to be yet-unknown forms of "dark matter" and "dark energy."

Witherell: ILC Offers Compelling Physics
The linear collider would provide such compelling physics opportunities that particle physics laboratories around the world have chosen to take a unified approach to developing the final design. The recent technology decision, taken by the international linear collider community as a whole, is an important and historic milestone in this approach. With the technology decision behind us, the particle physics community can now begin work on a global design for the ILC. Fermilab is a strong advocate of the physics that would come from a linear collider. Fermilab people have worked on the R&D for both of the technologies developed for the linear collider. We have committed to be a major participant in the International Linear Collider, whatever the technology choice. Now we are ready to work with our colleagues at SLAC, KEK, DESY and other institutions in establishing the global design effort. Although the technology decision presents a great opportunity to advance the ILC, we need to recognize the challenges ahead. Scientists and engineers at SLAC and at KEK have led a highly successful effort to establish the feasibility of the X-band approach, and we at Fermilab are proud to have built many of the accelerating structures that demonstrated that feasibility. It will take courage, effort and time for those who have invested their creative effort into the X-band R&D to put their hearts and minds into developing the superconducting design. To build an ILC, however, we will need their active participation and leadership.
For Fermilab and the field of particle physics, I congratulate and thank
the people who have made heroic efforts to develop two technologies. Both
would work for the linear collider. We need the best ideas from all of these
experts to develop the design for the ILC. For Fermilab's part, we will work
together with our colleagues around the world to realize the shared dream of
a linear collider and the great science that it will produce.
