The Large Detector Concept for the International Linear Collider is based on a large continuous gaseous tracker surrounded by a highly granular calorimeter.
The International Linear Collider (ILC) is a proposed linear particle accelerator. It is planned to have a collision energy of 500 GeV initially, and, if approved after the project has published its Technical Design Report, planned for 2012, could be completed in the late 2010s. A later upgrade to 1000 GeV is possible. The host country for the accelerator has not yet been chosen. Studies for a competing project called CLIC are also underway; it seems unlikely that both machines will be built.
The ILC would collide electrons with positrons. It will be between 30 km and 50 km (19-31 mi.) long, more than 10 times as long as the 50 GeV Stanford Linear Accelerator, the longest existing linear particle accelerator. The proposal was previously known by various names in different regions.
A revolution has begun in the way we see the universe.
In the past century, physicists have explored smaller and smaller scales, cataloguing and understanding the fundamental components of the universe, trying to explain the origin of mass and probing the theory of extra dimensions. And in recent years, experiments and observations have pointed to evidence that we can only account for a surprising five percent of the universe.
Scientists believe that the remaining 95 percent is a mysterious dark matter and dark energy, revealing a universe far stranger and more wonderful than they ever suspected. The global particle physics community agrees that a precision machine—the proposed International Linear Collider—will answer these questions about what the universe is made of and provide exciting new insights into how it works. Using unprecedented technology, discoveries are within reach that could stretch our imagination with new forms of matter, new forces of nature, new dimensions of space and time and bring into focus Albert Einstein’s vision of an ultimate unified theory.
