Where will CLIC be built?
It is presently assumed that CLIC will be built underground, near to CERN in the area close to Geneva.

How much power will CLIC use?
Designed to be a high luminosity, high energy linear collider, CLIC will inevitably need high power. Compared to an accelerator using superconducting technology, CLIC nevertheless has very low power consumption in stand-by or “waiting-for-beam” mode. A preliminary analysis of the overall CLIC energy consumption per year for the various stages shows that the first stage

Why does CLIC have sectors?
The two main CLIC linacs are each divided into 24 sectors. Each sector is 878 m long, and contains around 3000 accelerating structures. A fresh drive beam is injected into each sector to accelerate the main beam. At the end of the sector, the spent drive beam is dumped and a new drive beam is

What is special about CLIC accelerating cavities?
CLIC accelerating structures are designed and built to run very stably at a very high accelerating gradient (100 MV/m). The structures are built to micron-level tolerances to ensure that the beam quality is not degraded by beam-to-structure misalignment effects.

How many two-beam modules are needed for CLIC? How many accelerating structures?
Each 21 km main linac has 10,380 two-beam modules. Each two-beam module contains up to four PETS. Each PETS generates the RF power for two accelerating structures. CLIC therefore has 71,460 PETS and some 143,000 accelerating cavities in total. The LHC uses 8 accelerating cavities per beam.

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 drive beam is converted into RF power, which in

What does CLIC stand for? Why is this accelerator “compact”?
CLIC stands for the Compact Linear Collider. Despite a main accelerator of 42 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 distance of 840 km! Or alternatively, 700 km of LEP2 acceleration (6

EU project lights up X-band technology
EU project lights up X-band technology Advanced linear-accelerator technology developed at CERN and elsewhere will be used to develop a new generation of compact X-ray free-electron lasers (XFELs), thanks to a €3 million project funded by the European Commission’s Horizon 2020 programme. Beginning in January 2018, “CompactLight” aims to design the first hard XFEL based

CLIC in CERN Courier
CLIC in CERN Courier “An updated baseline-staging scenario for CERN’s Compact Linear Collider focuses on an optimised initial-energy stage at 380 GeV that will be significantly cheaper than the original design, say Philipp Roloff and Daniel Schulte..” Recent article in CERN Courier: “CLIC steps up to the TeV challenge”
