The Horizon 2020 Project EuPRAXIA ('European Plasma Research Accelerator with eXcellence In Applications') aims at producing a design report of a highly compact and cost-effective European facility with multi-GeV electron beams using plasma as the acceleration medium. The accelerator facility will be based on a laser and/or a beam driven plasma acceleration approach and will be used for photon science, high-energy physics (HEP) detector tests, and other applications such as compact X-ray sources for medical imaging or material processing.

The production of superconducting coatings for radio frequency (RF) cavities has been developed over several decades. It is widely accepted that for any further improvement in cavity RF performance, innovation is needed and one may have to turn to other forms of Nb and other superconducting materials. [...]

3D Tracking Methods in a GEANT4 Environment Through Electrostatic Beamlines
/ Hunt, James (U. Liverpool (main) ; Cockcroft Inst. Accel. Sci. Tech.) ; Resta-López, Javier (Cockcroft Inst. Accel. Sci. Tech. ; U. Liverpool (main)) ; Rodin, Volodymyr (U. Liverpool (main) ; Cockcroft Inst. Accel. Sci. Tech.) ; Veglia, Bianca (U. Liverpool (main) ; Cockcroft Inst. Accel. Sci. Tech.) ; Welsch, Carsten (U. Liverpool (main) ; Cockcroft Inst. Accel. Sci. Tech.)
Due to the relatively infrequent use of electrostatic beamline elements compared with their magnetic counterparts, there are few particle tracking codes which allow for the straightforward implementation of such beamlines. In this contribution, we present 3D tracking methods for beamlines containing electrostatic elements utilising a modified version of the Geant4 based tracking code 'G4beamline'. [...]

The next generation of high power, high intensity accelerators requires non-invasive diagnostics, particularly beam profile monitors. Residual gas-based diagnostics such as ionization beam profile or beam induced fluorescence monitors have been used to replace commonly used scintillating screens. [...]

First Measurements of Trojan Horse Injection in a Plasma Wakefield Accelerator

Plasma accelerators support accelerating fields of 100's of GV/m over meter-scale distances and routinely produce femtosecond-scale, multi-kA electron bunches. The so called Trojan Horse underdense photocathode plasma wakefield acceleration scheme combines state-of-the-art accelerator technology with laser and plasma methods and paves the way to improve beam quality as regards emittance and energy spread by many orders of magnitude.
