Laser ionized preformed plasma
The Facility for Advanced Accelerator and Experimental Tests (FACET) at SLAC installed a 10-TW Ti : sapphire laser system for pre-ionized plasma wakefield acceleration experiments. High energy (500 mJ), short (50 fs) pulses of 800 nm laser light at 1 Hz are used at the FACET experimental area to produce a plasma column. The laser pulses are stretched to 250 fs before injection into a vapor cell...
متن کاملPlasma Wakefield Experiments at Facet*
FACET, the Facility for Advanced Accelerator and Experimental Tests, is a new facility being constructed in sector 20 of the SLAC linac primarily to study beam driven plasma wakefield acceleration beginning in summer 2011. The nominal FACET parameters are 23GeV, 3nC electron bunches compressed to ~20μm long and focused to ~10μm wide. The intense fields of the FACET bunches will be used to field...
متن کاملGuiding of relativistic laser pulses by preformed plasma channels.
Guiding of relativistically intense (>10(18) W/cm2) laser pulses over more than 10 diffraction lengths has been demonstrated using plasma channels formed by hydrodynamic shock. Pulses up to twice the self-guiding threshold power were guided without aberration by tuning the guide profile. Transmitted spectra and mode images showed the pulse remained in the channel over the entire length. Experim...
متن کاملIntense Laser Pulse Guiding in Preformed Plasma Waveguides
Preformed plasma waveguides capable of controllably guiding relativistically intense femtosecond laser pulses over multiple Rayleigh lengths without optical distortion are essential to developing GeV-scale laser wakefield accelerators (LWFAs). We present recent experimental results showing guiding of pulses at intensities above 10 W/cm. Pump-probe experiments further characterize guided pulse p...
متن کاملPlasma wakefield acceleration experiments at FACET
FACET—Facilities for Accelerator science and Experimental Test beams at SLAC—will provide high-energy-density electron and positron beams with peak currents of roughly 20 kA that will be focused down to a 10μm× 10μm transverse spot size at an energy of ∼23GeV. With FACET, the SLAC linac will support a unique program concentrating on second-generation research in plasma wakefield acceleration. T...
