Electron Rephasing in a Truncated Tunable Plasma Channel
Arujash Mohanty, Santhosh Krishnamurthy, Yinren Shou +6
We report the acceleration of stable electron beams with energies up to 1.5 GeV using a 50 TW laser pulse guided in a preformed plasma channel generated by an axiparabola-focused h…
Direct observation of electron shedding from a laser-plasma accelerator
Sheroy Tata, Salome Benracassa, Heychal Davidovich +6
Laser-plasma accelerators have demonstrated the ability to produce ultrashort relativistic electron bunches with peak currents suitable for compact light sources, ultrafast diffrac…
Plasma wakefield dynamics of self-generated electron bunch trains
Salome Benracassa, Sheroy Tata, Yinren shou +2
Laser plasma accelerators can deliver high-energy, quasi-monoenergetic electron beams over centimeter-scale distances. In this work, we report on the generation of narrow, quasi-mo…
Electron Acceleration in a Flying-Focus Laser Wakefield Accelerator
Aaron Liberman, Anton Golovanov, Slava Smartsev +3
Structured light pulses hold significant promise for their ability to overcome dephasing in laser-wakefield accelerators, that should facilitate applications in high-energy physics…
Probing Flying-Focus Wakefields
Aaron Liberman, Anton Golovanov, Sheroy Tata +2
Flying-focus wakefields, which can propagate with a tunable velocity along the optical axis, are promising solutions to electron dephasing in laser-wakefield accelerators. This is…
First Electron Acceleration in a Tunable-Velocity Laser Wakefield
Aaron Liberman, Anton Golovanov, Slava Smartsev +3
We present the first experimental confirmation that a laser-wakefield accelerator produced by a flying focus pulse is able to maintain the coherent structures necessary to accelera…
A compact laser-plasma source for high-repetition-rate bi-modal X-ray and electron imaging
Angana Mondal, Ratul Sabui, Sonali Khanna +5
Bright sources of high-energy X-rays and electrons are indispensable tools in advanced imaging. Yet, current laser-driven systems typically support only single-modality imaging, re…
First direct observation of a wakefield generated with structured light
Aaron Liberman, Anton Golovanov, Slava Smartsev +6
The use of structured light to control the phase velocity of the wake in laser-wakefield accelerators has generated significant interest for its ability to mitigate electron dephas…
Compton photons at the GeV scale from self-aligned collisions with a plasma mirror
Aimé Matheron, Jean-Raphaël Marquès, Vincent Lelasseux +34
With today's multi-petawatt lasers, testing quantum electrodynamics (QED) in the strong field regime, where the electric field exceeds the Schwinger critical field in the rest fram…
Beam current from downramp injection in electron-driven plasma wakefields
Céline Hue, Anton Golovanov, Sheroy Tata +2
We study the stability of plasma wake wave and the properties of density-downramp injection in an electron-driven plasma accelerator. In this accelerator type, a short high-current…
Simple few-shot method for spectrally resolving the wavefront of an ultrashort laser pulse
Slava Smartsev, Aaron Liberman, Igor A. Andriyash +10
We present a novel and straightforward approach for the spatio-spectral characterization of ultrashort pulses. This minimally intrusive method relies on placing a mask with special…
