Demonstration of a beam loaded nanocoulomb-class laser wakefield accelerator.
Jurjen Couperus,Jurjen Couperus,Richard Pausch,Richard Pausch,Alexander Kohler,Alexander Kohler,O. Zarini,O. Zarini,J.M. Krämer,J.M. Krämer,Marco Garten,Marco Garten,Axel Huebl,Axel Huebl,René Gebhardt,U. Helbig,Stefan Bock,Karl Zeil,Alexander Debus,Michael Bussmann,Ulrich Schramm,Ulrich Schramm,Arie Irman +22 more
TL;DR: It is demonstrated in laser plasma wakefield electron acceleration that the beam loading effect can be employed to improve beam quality by controlling the beam charge and the final energy spread is minimized.

TL;DR: The calibration of scintillating screens commonly used to detect relativistic electron beams with low average current from laser-plasma accelerators is revised, based on new and expanded measurements that include higher charge density and different types of screens than previous work.
Making spectral shape measurements in inverse Compton scattering a tool for advanced diagnostic applications.

TL;DR: The potential of inverse Compton scattering as an advanced diagnostic tool is reported by investigating two of the most influential interaction parameters, namely the laser intensity and the electron beam emittance, by investigating the interaction to a nonlinear regime.
Improved performance of laser wakefield acceleration by tailored self-truncated ionization injection
Arie Irman,Jurjen Couperus,Jurjen Couperus,Alexander Debus,Alexander Kohler,Alexander Kohler,J.M. Krämer,J.M. Krämer,Richard Pausch,Richard Pausch,O. Zarini,O. Zarini,Ulrich Schramm,Ulrich Schramm +13 more
TL;DR: In this paper, the authors report on tailoring ionization-induced injection in laser wakefield acceleration so that the electron injection process is self-truncating following the evolution of the plasma bubble.
