The International Linear Collider From Design to Reality

Particle accelerators have been the primary tool of particle physics for over 60 years. They have enabled great advances and discoveries, the latest being the discovery of the Higgs boson at the Large Hadron Collider at CERN. Using complementary approaches of colliding protons on protons as a broad-band discovery device and colliding electrons on positrons as a precision probe of the physics, we have uncovered the basic constituents of matter and fundamental symmetries in nature. The International Linear Collider is the next advance in accelerators and will be the complementary electron-positron collider for the Large Hadron Collider. The ILC will enable precision studies of the underlying physics of the Higgs, a completely new kind of particle responsible for the creation of mass in nature.
