First Attempts in Automated Defect Recognition in Superconducting Radio-Frequency Cavities
The inner surface of superconducting cavities plays a crucial role to achieve highest accelerating fields. The industrial fabrication of cavities for the European X-Ray Free Electron Laser (EXFEL) and the International Linear Collider (ILC) HiGrade Research Project allowed for an investigation of this interplay with a large sample on different cavities undergoing a standardized procedure.

Numerical beam stability studies in external injection plasma-wakefield acceleration regimes
[DESY-THESIS-2019-005]
Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 177 pp. () [10.3204/PUBDB-2019-01791] = Dissertation, Universität Hamburg, 2019  GO
This work considers the phase-space evolution of an externally injectedelectron beam under various plasma-based acceleration scenariosusing numerical methods.Plasma wakefield acceleration, an exceptional technology with thepotential to drive the next generation of particle accelerators, uses aparticle driver to excite a wakefield carrying gradients in the rangeof10 GV m−1to100 GV m−1, orders of magnitude higher than theconventional cavities currently available. However, the plasma envi-ronment has stringent requirements with respect to acceptable beamparameters which need to be carefully analyzed to enable stable beamtransport and acceleration. [...]

Tunable Plasma-Based Energy Dechirper
A tunable plasma-based energy dechirper has been developed at FLASHForward to remove thecorrelated energy spread of a 681 MeV electron bunch. Through the interaction of the bunch withwakefields excited in plasma the projected energy spread was reduced from a FWHM of 1.31% to 0.33%without reducing the stability of the incoming beam [...]

Generation of quasi continuous-wave electron beams in an L-band normal conducting pulsed RF injector for laboratory astrophysics experiments
[arXiv:1803.05540]
 GO
We report on an approach to produce quasi continuous-wave (cw) electron beams with an average beam current of milliamperes and a mean beam energy of a few MeV in a pulsed RF injector. Potential applications are in the planned laboratory astrophysics programs at DESY. [...]
