Abstract
The
CLIC final focus system is designed based on the local compensation
scheme proposed by P. Raimondi and A. Seryi. However, there exist
remaining aberrations that deteriorate the performance of the system.
An optimization algorithm has been developed based on the computation
of the high orders of the transfer map using MAD-X and PTC. Its
application to the CLIC BDS is presented.
Rogelio presented his
non-linear optimization of the BDS (optimization of multipoles,
focussing and dispersion) that led to a total luminosity increase of
72% compared to the previous design.
His work is also published in CLIC note 659 (pdf

Andersson showed a computer animation movie of the bunch
combination in the Delay Loop and the Combiner Ring.
