“…The resulting maximum electric field of 2.20) observed in the simulations is attributed to the details of the trajectories of the blown-out electrons and hence the real shape of the bucket (including deviations from perfect spherical symmetry). This scaling has also shown very good agreement with experimental values for energy gain [14,13], and this value of the peak electric field is used throughout this thesis.…”

“…Furthermore, we show that by employing ionization-induced injection [15] this threshold can be overcome and broad spectrum electron beams with maximum energies exceeding 1 GeV are accessible using a gas cell target [13]. Finally, by tailoring the gas composition along the gas cell we demonstrate a reduction of the energy spread of our electron beams from 50% to 5% at peak energies of ∼0.5 GeV.…”

“…At the densities required for multi-GeV energy gain the self-trapping mechanism that was so advantageous breaks down [14]. Alternative injection schemes relying on ionization of higher-Z gases (ionization-induced injection) [15,16] than the traditional H 2 or He plasmas have been shown to be effective at densities several factors below the self-trapping threshold, but have generally led to large energy spread electron beams reminiscent of SMLWFA [13]. However, by tailoring the longitudinal gas composition of the target to limit the ionization-induced injection region, a 0.46 GeV electron beam with 5% energy spread has successfully been demonstrated [17].…”

“…Using such laser systems electron energy gains exceeding 1 GeV have been demonstrated [13,11] in the LWFA regime, with even higher energies on the horizon as higher power and higher repetition rate systems become available (such as the Texas Petawatt at University of Texas at Austin, the BELLA Laser at University of California at Berkeley and the proposed E23 at the Lawrence Livermore National Laboratory). These LWFA experiments have also made tremendous progress toward improving the quality of the electron beam, specifically in terms of energy spread.…”

“…By utilizing table-top 10TW-PW laser systems, high quality monoenergetic electron beams with energies up to few GeV [5][6][7][8][9][10][11] and energy spread of a few percent [12][13][14] have been obtained worldwide. In this paper, we report our recent experimental results on laser plasma acceleration utilizing a newly built facility at Tsinghua University.…”

A unique facility for laser plasma physics and advanced accelerator research has been built recently at Tsinghua Universtiy. This system is based on Tsinghua Thomson scattering X-ray source (TTX) [1,2], which combining an ultrafast TW laser with a synchronized 45MeV high brightness linac. In our recent laser wakefield acceleration experiments, we have obtained 10∼40MeV high quality monoenergetic electron beams by running the laser at 5TW peak power. Under certain conditions, very low relative energy spread of a few percent can be achieved. Absolute charge calibration for three different scintillating screens has also been performed using the linac system.An article usually includes an abstract, a concise summary of the work covered at length in the main body of the article.keyword: laser-plasma accelerator, monoenergetic, electron charge PACS numbers: 52.38.

The charge separation between electrons and ions that exists within an electron plasma density wave can create large electric fields. In 1979 Tajima and Dawson first recognized that the longitudinal component of the field of a so-called “relativistic” wave (one propagating with a phase velocity close to c), could be used to accelerate charged particles to high energies in a short distance [1]. The accelerating gradient of such a plasma wave, Eo, can be approximated—assuming a total separation of electrons and ions in such a wave with wavelength λp = 2πc/ωp—as
