Acceleration of laser-injected electron beams in an electron-beam driven plasma wakefield accelerator
[DESY-THESIS-2018-006]
Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY THESIS, 135 pp. (2018) [10.3204/PUBDB-2018-01381] = Dissertation, Universität Hamburg, 2018  GO
Plasma wakefields deliver accelerating fields that are approximately a 100 times higher thanthose in conventional radiofrequency or even superconducting radiofrequency cavities. Thisopens a transformative path towards novel, compact and potentially ubiquitous accelerators.These prospects, and the increasing demand for electron accelerator beamtime for various applicationsin natural, material and life sciences, motivate the research and development on novelplasma-based accelerator concepts.

Longitudinal Bunch Diagnostics using Coherent Transition Radiation Spectroscopy
[DESY-18-027; arXiv:1803.00608]
The generation and properties of transition radiation (TR) are thoroughly treated. The spectral energy density, as described by the Ginzburg-Frank formula, is computed analytically, and the modifications caused by the finite size of the TR screen and by near-field diffraction effects are carefully analyzed. [...]

Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY THESIS, 77 pp. (2018) [10.3204/PUBDB-2018-00788] = Masterarbeit, Universität Hamburg, 2018  GO
The use of a hollow plasma channel in plasma-based acceleration has ben-eficial properties for the acceleration of electron and positron bunches. Inthe scope of the FLASHForward facility at DESY, the generation of sucha plasma structure is examined. [...]

Optical surface properties and their RF limitations of European XFEL cavities
The inner surface of superconducting cavities plays a crucial role to achieve highest accelerating fields and low losses. The industrial fabrication of cavities for the European X-ray Free Electron Laser and the International Linear Collider HiGrade Research Project allowed for an investigation of this interplay. [...]

One of the key issues for generation of stable and reproducible beams in plasma particle accelerators is control of the initial plasma density distribution. Not only the longitudinal but also the transverse density profile, the species distribution as well as fragmentation and ionisation dynamics can have significant impact on the generated beams [...]

FLASHForward - A Future-Oriented Wakefield-Accelerator Research and Development Facility at FLASH
8th International Particle Accelerator Conference, IPAC2017, Meeting locationCopenhagen, Denmark, 14 May 2017 - 19 May 20172017-05-142017-05-19 Geneva : JACoW, 1692-1695 (2017) [10.18429/JACoW-IPAC2017-TUPIK006]  GO
FLASHForward is a beam-driven plasma wakefield acceleration facility, currently under construction at DESY (Hamburg, Germany), aiming at the stable generation of electron beams of several GeV with small energy spread and emittance. High-quality 1 GeV-class electron beams from the free-electron laser FLASH will act as the wake driver. [...]
