In a previous article (Papaphilippou & Laskar 1996), we used the frequency map analysis for studying the dynamics of the axisymmetric softened version of the logarithmic potential. The method is now applied to its 3-dimensional generalisa-tion in order to deepen our knowledge regarding the dynamics of triaxial power-law galactic models. The principal… (More)
The CLIC Damping rings are designed to produce unprecedentedly low-emittances of 500 nm and 5 nm nor-malised at 2.86 GeV, with high bunch charge, necessary for the performance of the collider. The large beam brightness triggers a number of beam dynamics and technical challenges. Ring parameters such as energy, circumference , lattice, momentum compaction,… (More)
In the framework of the CARE HHH European Network, we have developed a web-based dynamic accelerator-physics code repository. We describe the design, structure and contents of this repository, illustrate its usage, and discuss our future plans, with emphasis on code benchmark-ing.
The CLIC polarized positron source is based on a positron production scheme in which polarized photons are produced by a Compton process. In one option, Compton backscattering takes place in a so-called " Compton ring " , where an electron beam of 1 GeV interacts with circularly-polarized photons in an optical resonator. The resulting circularly-polarized… (More)
Space-charge effects have been identified as the most serious intensity limitation in the CERN PS and PS Booster, on the way towards ultimate LHC performance and beyond. We here explore the application of several previously proposed space-charge compensation methods to the two LHC pre-injector rings, and the challenges which need to be overcome. The methods… (More)
