GeV electron bunches accelerated on a centimeter scale device exemplify the extraordinary advances of laser-plasma acceleration. The combination of high charges from optimized injection schemes and intrinsic femtosecond short bunch duration yields kiloampere peak curren...

Dissertation to achieve the academic degree Doctor rerum naturalium. Handed in at Technische Universität Dresden. <strong>Abstract:</strong> Laser plasma wakefield accelerators have seen tremendous progress in the last years, now capable of producing electron beams in t...

We report in this paper the design and qualification of a cylindrical unbalanced magnetron source. The dedicated magnetic assemblies were simulated using a finite element model. A hall-effect magnetic probe was then used to characterize those assemblies and compared to ...

In this thesis an optimized calorimetry chamber is developed, providing at and easy mountable samples. Furthermore, it enables exchangeability of samples between the resonators at HZB and CERN. The thesis is structured as follows: First, a short introduction into SRF is...

Instrumentation of higher order modes (HOMs) excited in accelerating cavities for beam phase and position inference provides a noninvasive and economical beam diagnostic. The principles and techniques for this purpose are investigated for TESLA (TeV Energy Superconducti...
