Welcome to the ILD web site
International Large Detector (ILD)
ILD is a system of particle detectors which is being developed for the ILC. ILD combines excellent tracking and finely-grained calorimetry systems. This gives ILD the ability to reconstruct the energy of individual particles, known as the Particle Flow approach. The precision that can be achieved by ILD is ideal for studies in particle physics which call for accurate measurements of particles and their properties.

The International Linear Collider (ILC)
The ILC will be a particle accelerator to collide electrons against positrons. Because the positron is the anti-particle of the electron, the electron-positron pair will annihilate into pure energy. Depending on how the quantum mechanical die plays out, the pure energy could then turn into something interesting, such as the highly anticipated Higgs boson. Because the starting point is a pool of pure energy, when a Higgs boson emerges, it will be accompanied by relatively few other particles, which will make it particularly easy to identify the Higgs boson. This is very unlike the case at the LHC, where the proton-proton collisions result in many fragmented pieces of what was originally a proton, each fragment producing its own shower of particles.
Conventional particle accelerators are arranged into a ring, where the particles are gradually accelerated as they go around the ring many times. This method faces a limit as it becomes progressively more difficult to accelerate particles at higher energies, because the particles lose energy by emitting radiation when they are bent around the ring; this phenomenon is known as synchrotron radiation. To overcome this difficulty, the ILC accelerates electrons and positrons in a straight line. The challenge then is to develop accelerators which are powerful enough to impart the desired energy into the electrons and positrons in just one go.
