Stable and high quality electron beams from staged laser and plasma wakefield accelerators
F. M. Foerster, A. Döpp, F. Haberstroh +24
We present experimental results on a plasma wakefield accelerator (PWFA) driven by high-current electron beams from a laser wakefield accelerator (LWFA). In this staged setup stabl…
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…
Single shot phase contrast imaging using laser-produced Betatron x-ray beams
S. Fourmaux, S. Corde, K. Ta Phuoc +8
Development of x-ray phase contrast imaging applications with a laboratory scale source have been limited by the long exposure time needed to obtain one image. We demonstrate, usin…
Mapping the X-Ray Emission Region in a Laser-Plasma Accelerator
S. Corde, C. Thaury, K. Ta Phuoc +13
The x-ray emission in laser-plasma accelerators can be a powerful tool to understand the physics of relativistic laser-plasma interaction. It is shown here that the mapping of beta…
Controlled Betatron X-Ray Radiation from Tunable Optically Injected Electrons
S. Corde, K. Ta Phuoc, R. Fitour +5
The features of Betatron x-ray emission produced in a laser-plasma accelerator are closely linked to the properties of the relativistic electrons which are at the origin of the rad…
Quasistatic modeling of ultrarelativistic beam-plasma instabilities
P. San Miguel Claveria, L. Gremillet, X. Davoine +5
Relativistic particle beams propagating through dense ambient plasmas are susceptible to streaming instabilities that can govern the system dynamics in various astrophysical and la…
