With pinpoint accuracy, the next generation of Linear Collider such as CLIC will collide electron and positron beams at a centre of mass energy of 3 TeV with a desired peak luminosity of 2*1034 cm⁻²s^{−1}. One of the many challenging features of CLIC is its ability to collide beams at the sub-nanometer scale at the Interaction Point (IP). [...]

Vibration Control Using a Dedicated Inertial Sensor
/ Balik, Gael (Annecy, LAPP) ; Caron, Bernard (Savoie U. (main)) ; Aimard, Benjamin (Annecy, LAPP) ; Brunetti, Laurent (Annecy, LAPP) ; Deleglise, Guillaume (Annecy, LAPP)
The Compact Linear Collider (CLIC) project is right in the development phase. In this prospect, the main objective of the final focus stabilization is to succeed in damping ground motion vibration at the sub-nanometer scale to avoid any unwanted motion of the two last final focus magnets. [...]

Proof of Concept of CLIC Final Focus Quadrupoles Stabilization
/ Balik, Gael (Annecy, LAPP) ; Aimard, Benjamin (Annecy, LAPP) ; Brunetti, Laurent (Annecy, LAPP) ; Caron, Bernard (SYMME, Annecy)
The Compact LInear Collider (CLIC) [1] luminosity requires extremely low beam emittances. Therefore, high beam position stability is needed to provide cen-tral collisions of the opposing bunches [...]

Intra-beam IP Feedback Studies for the 380 GeV CLIC Beam Delivery System
/ Bodenstein, Ryan (Oxford U., JAI) ; Burrows, Philip (Oxford U., JAI) ; Plassard, Fabien (CERN) ; Snuverink, Jochem (Royal Holloway, U. of London)
In its currently-envisaged initial stage, the Compact Linear Collider (CLIC) will collide beams with a 380 GeV center of mass energy. To maintain the luminosity within a few percent of the design value, beam stability at the interaction point (IP) must be controlled at the sub-nanometer level. [...]

Improving the Performance of an Orbit Feed-forward Based on Quadrupole Motion at the KEK ATF

The high luminosity requirement for a future linear collider sets a demanding limit on the beam quality at the Interation Point (IP). Even the natural motion of the ground could misalign the quadrupole magnets to such an extent that the resulting dipole kicks would require compensation. [...]

Experimental Verification Towards Feed-Forward Ground Motion Mitigation at ATF2

Without counter measures, ground motion effects would deteriorate the performance of future linear colliders to an unacceptable level. An envisioned new ground motion mitigation method (based on feed-forward control) has the potential to improve the performance and to reduce the system cost compared to other proposed methods. [...]
