CBPM: IBS studies, tuning knobs against ground motion
→
Europe/Zurich
6/2-004 (CERN)
Participants: K. Artoos, L. Deacon, A. Gerbershagen, E. Ikarios, A. Latina, Y. Papaphilippou, J. Pfingstner, Y. Renier, D. Schulte, J. Snuverink, G. Sterbini, F. Stulle, A. Vivoli, Y.W. Wang, P. Zisopoulos
A.V. reported on the IBS studies for the damping rings. A benchmork of the code SIRE with existing theories gave good agreement. It might also be possible to compare SIRE simulations to measured data from SLS. For the damping rings the simulations showed a small deformation of initially gaussian distributions.
Following the presentation the cause of the deformation has been discussed.
J.S. disscused the performance of tuning knobs to mitigate ground motion. The required tuning time is too long. Either better knobs have to be found or a sub-set of the current knobs is identified which could allow a fast recovery to acceptable luminosity levels. Unfortunately, the simulations take rather long and simulatiing even one hour of beam time is out off reach.
