The high luminosity requirement for a future linear collider sets a demanding limit on the beam quality at the Interaction Point (IP). One potential source of luminosity loss is the motion of the ground itself. [...]

Improving the Performance of an Orbit Feed-forward Based on Quadrupole Motion at the KEK ATF
/ Bett, Douglas (CERN) ; Burrows, Philip (JAI, Oxford) ; Charrondière, Cedric (CERN) ; Christian, Glenn (JAI, Oxford) ; Jeremie, Andrea (Annecy, LAPP) ; Kubo, Kiyoshi (KEK, Tsukuba) ; Kuroda, Shigeru (KEK, Tsukuba) ; Naito, Takashi (KEK, Tsukuba) ; Okugi, Toshiyuki (KEK, Tsukuba) ; Patecki, Marcin (CERN) et al.
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. [...]

Ground Motion Compensation using Feed-forward Control at ATF2
/ Bett, Douglas (CERN) ; Charrondière, Cedric (CERN) ; Jeremie, Andrea (Annecy, LAPP) ; Kubo, Kiyoshi (KEK, Tsukuba) ; Kuroda, Shigeru (KEK, Tsukuba) ; Naito, Takashi (KEK, Tsukuba) ; Okugi, Toshiyuki (KEK, Tsukuba) ; Patecki, Marcin (CERN) ; Pfingstner, Juergen (CERN) ; Schulte, Daniel (CERN) et al.
Ground motion compensation using feed-forward control is a novel technique being developed to combat beam imperfections resulting from the vibration-induced misalignment of beamline components. The method is being evaluated experimentally at the KEK Accelerator Test Facility 2 (ATF2). [...]

Mitigation of ground motion effects in linear accelerators via feed-forward control
/ Pfingstner, J (CERN) ; Artoos, K (CERN) ; Charrondiere, C (CERN) ; Janssens, St (CERN) ; Patecki, M (CERN) ; Renier, Y (CERN) ; Schulte, D (CERN) ; Tomás, R (CERN) ; Jeremie, A (Annecy, LAPP) ; Kubo, K (Sokendai, Tsukuba ; KEK, Tsukuba) et al.
Ground motion is a severe problem for many particle accelerators, since it excites beam oscillations, which decrease the beam quality and create beam-beam offset (at colliders). Orbit feedback systems can only compensate ground motion effects at frequencies significantly smaller than the beam repetition rate. [...]

Experimental Verification Towards Feed-Forward Ground Motion Mitigation at ATF2
/ Pfingstner, Juergen (CERN) ; Artoos, Kurt (CERN) ; Charrondière, Cedric (CERN) ; Janssens, Stef (CERN) ; Patecki, Marcin (CERN) ; Renier, Yves (CERN) ; Schulte, Daniel (CERN) ; Tomás, Rogelio (CERN) ; Jeremie, Andrea ; Kubo, Kiyoshi et al.
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. [...]
