Vibration and luminosity frequency analysis of the SuperKEKB collider
/ Serluca, Maurizio (Annecy, LAPP) ; Balik, Gael (Annecy, LAPP) ; Brunetti, Laurent (Annecy, LAPP) ; Aimard, Benjamin (Annecy, LAPP) ; Dominjon, Agnes (Annecy, LAPP) ; Bambade, Philip (IJCLab, Orsay) ; Wallon, Sandry (IJCLab, Orsay) ; Di Carlo, Salvatore (CERN) ; Masuzawa, Mika (KEK, Tsukuba) ; Uehara, Sadaharu (KEK, Tsukuba)
The SuperKEKB collider has entered the physics production phase with the aim to reach its target luminosity of 6×1035 cm−2s−1. Vibrations of the accelerator elements, especially around the Interaction Point (IP), could limit the performance of the collider. [...]

What is the best displacement transducer for a seismic sensor?
/ Novotny, Peter (CERN ; Savoie U. (main)) ; Aimard, Benjamin (Annecy, LAPP) ; Balik, Gael (Annecy, LAPP) ; Brunetti, Laurent (Annecy, LAPP) ; Caron, Bernard (Savoie U. (main)) ; Gaddi, Andrea (CERN)
This paper presents a development of a seismic sensor for the future Compact Linear Collider (CLIC). Sensor in which three different types of sub-nanometre displacement transducers have been integrated: a Fabry-Pérot interferometer, an optical encoder and a capacitive transducer. [...]

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 [...]

Active Vibration Isolation System for CLIC Final Focus
/ Balik, Gael (Annecy, LAPP) ; Allemandou, Nicolas (Annecy, LAPP) ; Allibe, Julie (Annecy, LAPP) ; Baud, Jean Philippe (Annecy, LAPP) ; Brunetti, Laurent (Annecy, LAPP) ; Deleglise, Guillaume (Annecy, LAPP) ; Jeremie, Andrea (Annecy, LAPP) ; Vilalte, Sebastien (Annecy, LAPP) ; Caron, Bernard (Savoie U.) ; Hernandez, Camilo (Savoie U.)
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). [...]
