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: In this article , a stable, compact laser-driven proton source with energies greater than 60 MeV enables radiobiological in vivo studies, and the results demonstrate a complete laser driven proton research platform for diverse user-specific small animal models, able to deliver tunable single shot doses up to around 20 Gy to millimetre-scale volumes on nanosecond timescales.

TL;DR: In this article , a laser-plasma accelerator-driven free-electron laser in a seeded configuration is presented, where control over the radiation wavelength is accomplished, and the appearance of interference fringes, resulting from the interaction between the phase-locked emitted radiation and the seed, confirms longitudinal coherence.

TL;DR: In this article, the authors investigated the effect of spectral phase modulation on proton acceleration from solid foils irradiated with PW-class laser-pulses, where the highest proton cut-off energies were achieved for temporal pulse parameters that varied significantly from those of an ideally Fourier transform limited (FTL) pulse.
