Experimental Demonstration of Dephasing Reduction in an Optically Guided Laser-Plasma Accelerator
Ronan Lahaye, Igor A. Andriyash, Julien Gautier +5
Laser-plasma accelerators offer a compact means of producing high-energy electron beams, but their performance is fundamentally limited by dephasing between the accelerated electro…
Decoupling acceleration and wiggling in a laser-produced Betatron source
Julien Gautier, Igor Andriyash, Andreas Döpp +11
Betatron radiation is produced in Laser Plasma Accelerators when the electrons are accelerated and simultaneously wiggle across the propagation axis. The mechanisms of electron acc…
Highly-efficient electron ponderomotive acceleration in underdense plasmas
Lorenzo Martelli, Olena Kononenko, Igor Andriyash +16
Laser-plasma accelerators represent a promising technology for future compact accelerating systems, enabling the acceleration of tens of pC to above GeV over just a few centim…
Controlled acceleration of GeV electron beams in an all-optical plasma waveguide
Kosta Oubrerie, Adrien Leblanc, Olena Kononenko +9
Laser-plasma accelerators produce electric fields of the order of 100 GV/m, more than 1000 times larger than radio-frequency accelerators. Thanks to this unique field strength, the…
Hard X-rays from laser-wakefield accelerators in density tailored plasmas
Michaela Kozlova, Igor Andriyash, Julien Gautier +10
Betatron x-ray sources from laser-plasma accelerators combine compactness, high peak brightness, femtosecond pulse duration and broadband spectrum. However, when produced with Tera…
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…
An all-optical Compton source for single-exposure X-ray imaging
A. Döpp, E. Guillaume, C. Thaury +8
All-optical Compton sources are innovative, compact devices to produce high energy femtosecond X-rays. Here we present results on a single-pulse scheme that uses a plasma mirror to…
Stable and polarized Betatron x-ray radiation from a laser plasma accelerator in ionization injection regime
Andreas Doepp, Benoit Mahieu, Antoine Doche +15
Betatron x-ray source from laser plasma interaction combines high brightness, few femtosecond duration and broad band energy spectrum. However, despite these unique features the Be…
Demonstration of relativistic electron beam focusing by a laser-plasma lens
Cédric Thaury, Emilien Guillaume, Andreas Döpp +11
Laser-plasma technology promises a drastic reduction of the size of high energy electron accelerators. It could make free electron lasers available to a broad scientific community,…
All-optical Compton gamma-ray source
K. Ta Phuoc, S. Corde, C. Thaury +6
One of the major goals of research for laser-plasma accelerators is the realization of compact sources of femtosecond X-rays. In particular, using the modest electron energies obta…
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…
