Compact Multistage Plasma-Based Accelerator Design for Correlated Energy Spread Compensation
[arXiv:1811.07757]
The extreme electromagnetic fields sustained by plasma-based accelerators could drastically reduce the size and cost of future accelerator facilities. However, they are also an inherent source of correlated energy spread in the produced beams, which severely limits the usability of these devices. [...]

Self-Modulation Instability of Electron Beams in Plasma Channels of Variable Length
10th International Particle Accelerator Conference, IPAC’19, MelbourneMelbourne, Australia, 19 May 2019 - 24 May 20192019-05-192019-05-24 Geneva, Switzerland : JACoW Publishing 3616-3618 () [10.18429/JACOW-IPAC2019-THPGW017]  GO
The self-modulation instability (SMI) of long (in respect to the plasma wavelength) charged particle beams passing through plasma enables the use of currently existing high energy charged particle beams as drivers for plasma wakefield accelerators. At the Photo Injector Test facility at DESY in Zeuthen (PITZ) the SMI of electron beams is studied *, **. [...]

Simulation of a Concept for a Compact Ultrafast X-ray Pulse Source Based on RF and THz Technologies
We study through simulations a layout mixing RF and THz technologies for a compact ultrafast X-ray pulse source based on Inverse Compton Scattering (ICS), aiming to deliver few femtoseconds to sub-femtosecond pulses. The layout consists of an S-band gun as the electron source and a dielectric-loaded circular waveguide driven by a multicycle THz pulse to accelerate and longitudinally compress the bunch, before X-ray generation via ICS with a laser pulse.

Using Short Drive Laser Pulses to Achieve Net Focusing Forces in Tailored Dual Grating Dielectric Structures
[arXiv:1801.10373]
Laser-driven grating type DLA (Dielectric Laser Accelerator) structures have been shown to produce accelerating gradients on the order of GeV/m. In simple $\beta$-matched grating structures due to the nature of the laser induced steady-state in-channel fields the per period forces on the particles are mostly in longitudinal direction. [...]
