All-optical density downramp injection in electron-driven plasma wakefield accelerators
D. Ullmann, P. Scherkl, A. Knetsch +16
Injection of well-defined, high-quality electron populations into plasma waves is a key challenge of plasma wakefield accelerators. Here, we report on the first experimental demons…
Plasma-photonic spatiotemporal synchronization of relativistic electron and laser beams
Paul Scherkl, Alexander Knetsch, Thomas Heinemann +23
Modern particle accelerators and their applications increasingly rely on precisely coordinated interactions of intense charged particle and laser beams. Femtosecond-scale synchroni…
Probing Ultrafast Magnetic-Field Generation by Current Filamentation Instability in Femtosecond Relativistic Laser-Matter Interactions
G. Raj, O. Kononenko, A. Doche +28
We present experimental measurements of the femtosecond time-scale generation of strong magnetic-field fluctuations during the interaction of ultrashort, moderately relativistic la…
Controlling injection using a magnetic field to produce sub-femtosecond bunches in the laser wakefield accelerator
Q. Zhao, S. M. Weng, M. Chen +5
It is shown that electron injection into a laser-driven plasma bubble can be manipulated by applying an external magnetic field in the presence of a plasma density gradient. The do…
Ionization injection in a laser wakefield accelerator subject to a transverse magnetic field
Q. Zhao, S. M. Weng, Z. M. Sheng +6
The effect of an external transverse magnetic field on ionization injection of electrons in a laser wakefield accelerator (LWFA) is investigated by theoretical analysis and particl…
High quality electron beam acceleration by ionization injection in laser wakefields with mid-infrared dual-color lasers
Ming Zeng, Ji Luo, Min Chen +3
For the laser wakefield acceleration, suppression of beam energy spread while keeping sufficient charge is one of the key challenges. In order to achieve this, we propose bichromat…
