Description
BDS tuning knobs, impact of knobs on CLIC tuning, decelerator alignment using the girder movers
Participants: F. Antoniou, J. Barranco, R. Corsini, B. Dalena, K. Elsener, B. Jeanneret, A. Latina, R. Lillestol, C. Maidana, E. Marin, M. Modena, J. Pfingstner, D. Schulte, P. Skowronski, G. Sterbini, F. Stulle, F. Tecker, A. Vivoli, Y.W. Wang
G.S. presented results of decelerator misalignment studies. In contrast to previous studies, which used movers for each quadrupole, it was tried to use only the girder movers. The results are promising but need further improvements and understanding of some unexpected behavior. It was discussed whether the implementation of the correction algorithms is fully correct. G.S. will check them and also the calculation of the response matrices.
E.M. discussed the creation of orthogonal tuning knobs for a final focus system. The method has been applied to the ATF2 FFS and good experimental results have been achieved.
B.D. simulated the impact of tuning knobs on CLIC luminosity. The method seems to work well, though a fast luminosity signal would be required. Hadronic events seem to be a good candidate for such a signal.
