Low-emittance electron bunches from a laser-plasma accelerator measured using single-shot x-ray spectroscopy.
X-ray spectroscopy is used to obtain single-shot information on electron beam emittance in a low-energy-spread 0.5 GeV-class laser-plasma accelerator. Measurements of betatron radiation from 2 to 20 keV used a CCD and single-photon counting techniques. By matching x-ray spectra to betatron radiation models, the electron bunch radius inside the plasma is estimated to be ~0.1 μm. Combining this w...
متن کاملRelativistic attosecond electron bunches from laser-illuminated droplets.
The generation of relativistic attosecond electron bunches is observed in three-dimensional, relativistic particle-in-cell simulations of the interaction of intense laser light with droplets. The electron bunches are emitted under certain angles which depend on the ratios of droplet radius to wavelength and plasma frequency to laser frequency. The mechanism behind the multi-MeV attosecond elect...
متن کاملLaser Plasma Electron Linear Accelerator
The generation of an ultrashort relativistic electron bunch from a strong laser-plasma interaction have been studied by particle-in-cell simulations and observed experimentally. The electron beam was generated from the plasma created by focusing a Ti: sapphire 12 TW (tera watt) laser pulse at the edge of helium gas jet expanded into the vacuum from a pulsed supersonic nozzle. The laser pulse du...
متن کاملCompression of High-charge Electron Bunches
The AØ Photoinjector at Fermilab can produce high charge (10-14 nC) electron bunches of low emittance (20 mmmrad for 12 nC). We have undertaken a study of the optimal compression conditions. Off-crest acceleration in the 9-cell capture cavity induces an energy-time correlation, which is rotated by the compressor chicane (4 dipoles). The bunch length is measured using streak camera images of opt...
متن کاملTerahertz radiation from laser accelerated electron bunches
Coherent terahertz and millimeter wave radiation from laser accelerated electron bunches has been measured. The bunches were produced by tightly focusing ~spot diameter '6 mm) a high peak power ~up to 10 TW!, ultra-short (>50 fs) laser pulse from a high repetition rate ~10 Hz! laser system ~0.8 mm!, onto a high density (.10 cm) pulsed gas jet of length '1.5 mm. As the electrons exit the plasma,...
