CLIC detector

CLICdp, the CLIC detector and physics study, is an international collaboration presently comprising 30 institutes.

The CLIC detector concept

The collaboration performs detector and physics studies for the future Compact Linear Collider (CLIC), a high-energy electron-positron accelerator which is one of the options for the next collider to be built at CERN. CLIC is foreseen to be built and operated in three energy stages, starting with a first stage at 380 GeV, followed by successive stages at 1.5 TeV and 3 TeV.

The physics programme for CLIC adresses precision measurements of the Higgs boson and the top quark, as well as direct and indirect searches for physics Beyond the Standard Model (BSM). The three CLIC energy stages each provide unique information on these physics subjects.  
 
clic_d_with_particle.pngThe CLIC detector has to fulfil precision requirements driven by the physics goals, while at the same time operating under challenging beam-induced background conditions. The detector comprises a precise low-mass vertex and tracking system based on silicon detector technology. It is surrounded by a fine-grained calorimeter system, composed of an electromagnetic calorimeter (ECAL), based on tungsten absorbers and silicon sensors, and a hadron calorimeter (HCAL), based on steel absorbers and small scintillator tiles read out by silicon photomultipliers. The tracking and calorimeter systems are placed inside a superconducting solenoid with a 4 Tesla field. Fine-grained electromagnetic calorimeters (BeamCal and Lumical) are surrounding the beams in the forward directions. All detector have time-stamping capabilities in the 1-10 ns range, allowing for efficient suppression of beam-induced backgrounds in the data.

The CLICdp collaboration actively pursues cutting-edge R&D in silicon-based vertex and tracking detectors and in fine-grained calorimetry.
