Contemporary design of efficient linear accelerator is based on ideal periodical structures with an optimi-sation for perfect periodicity. However, practical reali-sation involves random errors in the structure (e.g. [...]

The GLC algorithm allows the construction of efficient transfer lines with defined imaging properties using a minimum number of quadrupole elements. This work describes a generalization of this algorithm to make it applicable to the use of arbitrary beam optical elements. [...]

The High Energy Storage Ring (HESR) has been designed for acceleration and storage of antiprotons and ions by Forschungszentrum Jülich (FZ-Jülich) for FAIR in Darmstadt. The HESR kicker magnets have been designed for the injection of charged particles with magnetic rigidity of 13 Tm [...]

The first part of this work addresses the automatic online tuning of transfer lines in particle accelerator facilities. In the second part the focus lies on the automatic construction and optimisation of such transport lines. [...]

The high-energy beam transfer lines at GSI serve numerous experimental stations such as HADES, HTC and HTD as well as the fragment separator FRS and the storage rings ESR and CRYRING with a wide range of different heavy ion beams from the SIS18 synchrotron. The large amount of experiments carried out during beam times under different beam conditions require frequent changes of beam optics and beam steering in the transfer lines. [...]

Experiments at CRYRING using beams accelerated and decelerated in the accelerator chain SIS18 - ESR - CRYRING at GSI are considered as the first real FAIR experiments. For these experiments, CRYRING receives fast extracted beams from the ESR, which are cooled and decelerated down to about 10 MeV/u in the ESR. [...]
