A plasma photocathode for spin-polarized electron beams via state-selected hydrogen halide photofragments
Lars Reichwein, Thomas C. Wilson, Dimitris Sofikitis +6
Spin-polarized electron beams are essential tools for probing fundamental symmetries and for the search beyond the Standard Model. While plasma-based accelerators are a promising p…
Pinching injection in wakefields for spin-polarized electron beams
Lars Reichwein, Dimitris Sofikitis, Oliver Mathiak +5
Pinching of the driver beam in plasma wakefield acceleration is generally considered an unwanted effect that needs to be mitigated. Here, we propose that this effect can be utilize…
Efficient Acceleration of High-Quality GeV-Electron Bunches in a Hybrid Laser- and Beam-Driven Plasma Wakefield Accelerator
F. M. Foerster, M. Ayache, Z. Bi +24
Plasma-based accelerators are compact and provide high gradients, yet their practical use has been limited by energy gain, stability, beam quality, and energy transfer efficiency.…
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…
Ultra-high-gain water-window X-ray laser driven by plasma photocathode wakefield acceleration
Lily H. A. Berman, David Campbell, Edgar Hartmann +4
X-ray free-electron lasers are large and complex machines, limited by electron beam brightness. Here we show through start-to-end simulations how to realise compact, robust and tun…
Comparing a radiation damage model for avalanche photodiodes through in-situ observation of CubeSat based devices
Arpad Lenart, Tanvirul Islam, Srihari Sivasankaran +4
Space-based quantum technologies are essential building blocks for global quantum networks. However, the optoelectronic components used can be susceptible to radiation damage. Pred…
