Superconducting technology chosen for international project

摘要

The international committee for Future Accelerators (ICFA) announced on August 20 that it has chosen a supercooled, superconducting magnet approach for the proposed International Linear Collider (ILC), an electron-positron accelerator with peak energy in the range of 0.5 to 1.0 TeV. In making its decision, the ICFA agreed with its International Technology Recommendation Panel (ITRP), which favored the superconducting approach over a room-temperature "X-band" approach. The decision, announced at a conference in Beijing, China, was the first major step in the process toward shifting high-end particle physics research to worldwide organizations, as the demands of the field increasingly can be met only by several nations collaborating and sharing costs.
