Physics
Physics What is the most important physics measurement for CLIC to make? There are many interesting physics measurements that can be made at CLIC, and we might not know which ones are important until afterwards! Unexplained new physics from LHC data would certainly be a priority. Higgs measurements complementary to LHC results are also particularly

Detector
Detector What is the general design of the CLIC detector? The CLIC detector is actually a series of sub-detectors, working together to record the event. The different detectors fit together in concentric layers, with the collision happening at the centre. The inner layers are for particle tracking. They are very thin and light, so as

Beams
Beams What particles make up the beams? Why these particles? Why polarise electrons? The CLIC beams will be made of point-like particles: electrons (in one beam) and positrons (in the other beam). These two particles are matter-antimatter partners. When they come into contact in the collision they will annihilate each other, liberating all their energy

Accelerator
Accelerator What is special regarding the CLIC accelerating scheme? In a classical approach, the linear accelerators used to accelerate the beams would be powered by Radio Frequency (RF) power supplies, called klystrons. In the CLIC acceleration scheme, the klystrons are replaced with an intense particle beam, called the drive beam. The kinetic energy in the

Construction
Construction Where will CLIC be built? It is presently assumed that CLIC will be built underground, near to CERN in the area close to Geneva. However, the CLIC design could also be implemented elsewhere. What length will the CLIC tunnel be? The length of the accelerator complex varies according to the centre-of-mass energies: What diameter

General
General What does CLIC stand for? Why is this accelerator “compact”? CLIC stands for the Compact Linear Collider. Despite a main accelerating part of 44 km in length, the accelerator is “compact” due to its high accelerating gradient of 100 MV/m. To achieve the same centre-of-mass energy with LHC acceleration (5 MV/m) would require a
