Low divergence proton beams from a laser-plasma accelerator at kHz repetition rate
Dan Levy, Igor A. Andriyash, Stefan Haessler +6
Proton beams with up to 100 pC bunch charge, 0.48 MeV cut-off energy and divergence as low as a were generated from solid targets at kHz repetition rate by a few-mJ fem…
Efficiency and beam quality for positron acceleration in loaded plasma wakefields
C. S. Hue, G. J. Cao, I. A. Andriyash +5
Accelerating particles to high energies in plasma wakefields is considered to be a promising technique with good energy efficiency and high gradient. While important progress has b…
Axiparabola: a new tool for high-intensity optics
Kosta Oubrerie, Igor A. Andriyash, Ronan Lahaye +3
An axiparabola is a reflective aspherical optics that focuses a light beam into an extended focal line. The light intensity and group velocity profiles along the focus are adjustab…
Spatiotemporal dynamics of ultrarelativistic beam-plasma instabilities
P. San Miguel Claveria, X. Davoine, J. R. Peterson +28
An electron or electron-positron beam streaming through a plasma is notoriously prone to micro-instabilities. For a dilute ultrarelativistic infinite beam, the dominant instability…
Bright synchrotron radiation from relativistic self-trapping of a short laser pulse in near-critical density plasma
M. G. Lobok, I. A. Andriyash, O. E. Vais +2
In a dense gas plasma a short laser pulse propagates in relativistic self-trapping mode, which enables effective conversion of laser energy to the accelerated electrons. This regim…
Waveform control of relativistic electron dynamics in an underdense plasma
Julius Huijts, Lucas Rovige, Igor A. Andriyash +6
The interaction of ultra-intense laser pulses with an underdense plasma is used in laser-plasma acceleration to create compact sources of ultrashort pulses of relativistic electron…
Symmetric and asymmetric shocked gas jets for laser-plasma experiments
Lucas Rovige, Julius Huijts, Aline Vernier +9
Shocks in supersonic flows offer both a high-density and sharp density gradients that can be used, for instance,for gradient injection in laser-plasma accelerators. We report on a…
