Anticorrelation between Ion Acceleration and Nonlinear Coherent Structures from Laser-Underdense Plasma Interaction
F. Sylla, A. Flacco, S. Kahaly +5
In laser-plasma experiments, we observed that ion acceleration from the Coulomb explosion of the plasma channel bored by the laser, is prevented when multiple plasma instabilities…
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…
Non-invasive characterization of transverse beam emittance of electrons from a laser-plasma wakefield accelerator in the bubble regime using betatron x-ray radiation
S. Kneip, C. McGuffey, J. L. Martins +17
We propose and use a technique to measure the transverse emittance of a laser-wakefield accelerated beam of relativistic electrons. The technique is based on the simultaneous measu…
Comment on "Scalings for radiation from plasma bubbles" [Phys. Plasmas 17, 056708 (2010)]
S. Corde, A. Stordeur, V. Malka
Thomas has recently derived scaling laws for X-ray radiation from electrons accelerated in plasma bubbles, as well as a threshold for the self-injection of background electrons int…
Plasma wave undulator for laser-accelerated electrons
S. Corde, K. Ta Phuoc
Laser-plasma accelerators have become compact sources of ultrashort electron bunches at energies up to the gigaelectronvolt range thanks to the remarkable progress made over the pa…
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…
