Development of a a YAG/OTR Monitor / Yang, Renjun (Orsay, LAL) ; Aryshev, Alexander (KEK, Tsukuba) ; Bambade, Philip (Orsay, LAL) ; Bergamaschi, Michele (CERN) ; Naito, Takashi (KEK, Tsukuba) ; Terunuma, Nobuhiro (KEK, Tsukuba) ; Wallon, Sandry (Orsay, LAL)
To investigate the mechanisms of beam halo formation and its dynamics, a YAG/OTR monitor has been developed and tested at the KEK-ATF. The monitor has four ceramic Ce:YAG  screens for the visualization of the beam core and beam halo and an OTR target to provide complementary beam core measurements. [...]

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. [...]

Progress in Ultra-Low β* Study at ATF2 / Patecki, Marcin (CERN) ; Bett, Douglas (CERN) ; Kubo, Kiyoshi (KEK, Tsukuba ; Sokendai, Tsukuba) ; Kuroda, Shigeru (KEK, Tsukuba ; Sokendai, Tsukuba) ; Naito, Takashi (KEK, Tsukuba ; Sokendai, Tsukuba) ; Okugi, Toshiyuki (KEK, Tsukuba ; Sokendai, Tsukuba) ; Plassard, Fabien (CERN) ; Tauchi, Toshiaki (KEK, Tsukuba ; Sokendai, Tsukuba) ; Terunuma, Nobuhiro (KEK, Tsukuba ; Sokendai, Tsukuba) ; Tomás, Rogelio (CERN)
A nanometer beam size in the interaction point (IP) is required in case of future linear colliders for achieving the desired rate of particle collisions. KEK Accelerator Test Facility (ATF2), a scaled down implementation of the beam delivery system (BDS), serves for investigating the limits of electron beam focusing at the interaction point. [...]

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). [...]

Contribution of Optical Aberrations to Spot-size Increase with Bunch Intensity at ATF2 / Patecki, Marcin (CERN ; Warsaw U. of Tech.) ; Kubo, Kiyoshi (KEK, Tsukuba) ; Kuroda, Shigeru (KEK, Tsukuba) ; Naito, Takashi (KEK, Tsukuba) ; Okugi, Toshiyuki (KEK, Tsukuba) ; Tauchi, Toshiaki (KEK, Tsukuba) ; Terunuma, Nobuhiro (KEK, Tsukuba) ; Tomás, Rogelio (CERN) ; White, Glen (SLAC) ; Zimmermann, Frank (CERN)
A primary goal of ATF2 (Accelerator Test Facility) is to demonstrate a low vertical beam size at the interaction point (IP) of about 37 nm. Measurements over the past years indicate that the ATF2 vertical beam size strongly rises with bunch intensity. [...]

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. [...]
