Plasma dechirper and lens for electron beams from laser wakefield acceleration in a tailored density profile
T. L. Steyn, A. Panchal, O. Vasilovici +16
Achieving high-quality electron beams from laser wakefield accelerators critically relies on density tailoring to control electron dynamics during injection, acceleration, and extr…
Adaptable phase retrieval for coherent transition radiation spectroscopy based on differentiable physics information
Ritz Ann Aguilar, Maxwell LaBerge, Andreas Doepp +6
Coherent transition radiation (CTR) spectroscopy is a critical diagnostic for characterizing the longitudinal structure of relativistic electron bunches in laser-plasma and convent…
Patch-MLP-Based Predictive Control: Simulation of Upstream Pointing Stabilization for PHELIX Laser System
Jiaying Wang, Jonas Benjamin Ohland, Yen-Yu Chang +8
High-energy laser facilities such as PHELIX at GSI require excellent beam pointing stability for reproducibility and relative independence for future experiments. Beam pointing sta…
Gas-jet target with online interferometric thickness measurement for nuclear astrophysics
Anup Yadav, Daniel Bemmerer, Fabian Donat +10
A new jet gas target system has been developed for the Felsenkeller 5 MV underground ion accelerator for nuclear astrophysics. It provides either a 1.5 cm thi…
Self-Adaptive Stabilization and Quality Boost for Electron Beams from All-Optical Plasma Wakefield Accelerators
D. Campbell, T. Heinemann, A. Dickson +14
Shot-to-shot fluctuations in electron beams from laser wakefield accelerators present a significant challenge for applications. Here, we show that instead of using such fluctuating…
Observation of laser plasma accelerated electrons with transverse momentum spread below the thermal level
T. L. Steyn, A. Panchal, O. Vasilovici +14
Achieving high-quality electron beams from laser-plasma accelerators critically relies on density tailoring to control electron dynamics during injection, acceleration, and extract…
