Parametric amplification of laser-driven electron acceleration in underdense plasma.
A new mechanism is reported that increases electron energy gain from a laser beam of ultrarelativistic intensity in underdense plasma. The increase occurs when the laser produces an ion channel that confines accelerated electrons. The frequency of electron oscillations across the channel is strongly modulated by the laser beam, which causes parametric amplification of the oscillations and enhan...
متن کاملLaser 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 کاملApproximate Analytical Description of the Underdense Short Plasma Lens
The perturbative approach for describing the underdense plasma–ultrarelativistic electron bunch system is developed,using the ratio n0 nb as a small parameter (nb-bunch,n0plasma electron densities). Focusing of the electron bunch emerged in the first approximation of the perturbative procedure as a result of the plasma electrons redistribution.Focusing gradient and strength for ultrarelativisti...
متن کاملUCLA/FNPL Underdense Plasma Lens Experiment: Results and Analysis
Focusing of a 15 MeV, 16 nC electron bunch by a gaussian underdense plasma lens operated just beyond the threshold of the underdense condition has been demonstrated. The strong 1.9 cm focal length plasma lens focused both transverse directions simultaneously and reduced the minimum area of the beam spot by a factor of 23. Analysis of the beam envelope evolution observed near the beam waist show...
متن کاملUnderdense Plasma Lens Experiment at the Ucla Neptune Laboratory
An underdense plasma-lens experiment is planned at the UCLA Neptune Laboratory. For this experiment, a LaB6based discharge plasma source was developed and tested. Test results of the plasma source show that it can provide satisfactory argon plasma parameters for underdense plasma lens experiments, i.e., a density in low 10 cm 3 range and a thickness of a few cm. In the plasma chamber a YAG slab...
