Ground Motion

Ground Motion. Dynamic imperfections will affect luminosity performance or cost Most imperfections should be site independent Ground motion is not TRC: TESLA loses 15% luminosity in noisy site, if no luminosity optimisation is done within pulse Impact on static tuning not yet studied.

Presentation Transcript

  1. Ground Motion Dynamic imperfections will affect luminosity performance or cost Most imperfections should be site independent Ground motion is not TRC: TESLA loses 15% luminosity in noisy site, if no luminosity optimisation is done within pulse Impact on static tuning not yet studied

  2. Decision Needed • Is the ground motion part of the site selection? • Probably too late • Is the ground motion to be mitigated by stabilisation? • We could also accept loss in performance • GG4 will provide ground motion spectra
