Femtosecond x rays from laser-plasma accelerators
S. Corde, K. Ta Phuoc, A. Beck +5
Relativistic interaction of short-pulse lasers with underdense plasmas has recently led to the emergence of a novel generation of femtosecond x-ray sources. Based on radiation from…
Observation of longitudinal and transverse self-injections in laser-plasma accelerators
S. Corde, C. Thaury, A. Lifschitz +7
Laser-plasma accelerators can produce high quality electron beams, up to giga-electronvolts in energy, from a centimeter scale device. The properties of the electron beams and the…
Tuning the electron energy by controlling the density perturbation position in laser plasma accelerators
P. Brijesh, C. Thaury, K. Ta Phuoc +6
A density perturbation produced in an underdense plasma was used to improve the quality of electron bunches produced in the laser-plasma wakefield acceleration scheme. Quasi-monoen…
Real-time monitoring via second-harmonic interferometry of a flow gas cell for laser wakefield acceleration
F. Brandi, F. Giammanco, F. Conti +3
The use of a gas cell as a target for laser weakfield acceleration (LWFA) offers the possibility to obtain stable and manageable laser-plasma interaction process, a mandatory condi…
Deep Learning for EELS hyperspectral images unmixing -- using autoencoders
N. Brun, G. Lambert, L. Bocher
Spatially resolved Electron Energy-Loss Spectroscopy (EELS) conducted in a Scanning Transmission Electron Microscope (STEM) enables the acquisition of hyperspectral images (HSIs).…
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…
Quantum-limited mass flow of liquid He
G. Lambert, G. Gervais, W. J. Mullin
We consider theoretically the possibility of observing unusual quantum fluid behavior in liquid He and solutions of He in He systems confined to nano-channels. In…
Probing electron acceleration and X-ray emission in laser-plasma accelerator
C. Thaury, K. Ta Phuoc, S. Corde +6
While laser-plasma accelerators have demonstrated a strong potential in the acceleration of electrons up to giga-electronvolt energies, few experimental tools for studying the acce…
Betatron emission as a diagnostic for injection and acceleration mechanisms in laser-plasma accelerators
S. Corde, C. Thaury, K. Ta Phuoc +9
Betatron x-ray emission in laser-plasma accelerators is a promising compact source that may be an alternative to conventional x-ray sources, based on large scale machines. In addit…
