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…
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…
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…
Laser structured micro-targets generate MeV electron temperature at W/cm
Angana Mondal, Ratul Sabui, Sheroy Tata +14
Relativistic temperature electrons higher than 0.5 MeV are generated typically with laser intensities of about 10 W/cm. Their generation with high repetition rate lase…
Temporal Feedback Control of High-Intensity Laser Pulses to Optimize Ultrafast Heating of Atomic Clusters
M. J. V. Streeter, S. J. D. Dann, J. D. E. Scott +27
We describe how active feedback routines can be applied at limited repetition rate (5 Hz) to optimize high-power TW) laser interactions with clustered gases. Optimization of…
