“…They demonstrated ~5 x 10 4 hard x-ray photons (or 240 pJ) at 30 keV in 300 fs using 60-mJ, 100-fs (FWHM) laser pulses interacting with 20-ps (FWHM), ~1.3 nC electron bunches in a 90-deg geometry. Subsequently, several groups demonstrated a Thomson source with similar results [20], [21]. The early experiments enabled the demonstration of a pump probe diffraction experiment, where a sample of InSb was heated by a laser and probed by the Thomson source [5].…”

PLEIADES: high peak brightness, subpicosecond Thomson hard x-ray source

et al. 2003

The Picosecond Laser-Electron Inter-Action for the Dynamic Evaluation of Structures (PLEIADES) facility, is a unique, novel, tunable (10-200 keV), ultrafast (ps-fs), hard x-ray source that greatly extends the parameter range reached by existing 3 rd generation sources, both in terms of x-ray energy range, pulse duration, and peak brightness at high energies. First light was observed at 70 keV early in 2003, and the experimental data agrees with 3D codes developed at LLNL. The x-rays are generated by the interaction of a 50 fs Fourier-transform-limited laser pulse produced by the TW-class FALCON CPA laser and a highly focused, relativistic (20-100 MeV), high brightness (1 nC, 0.3-5 ps, 5 mm.mrad, 0.2% energy spread) photo-electron bunch. The resulting x-ray brightness is expected to exceed 10 20 ph/mm 2 /s/mrad 2 /0.1% BW. The beam is well-collimated (10 mrad divergence over the full spectrum, 1 mrad for a single color), and the source is a unique tool for time-resolved dynamic measurements in matter, including high-Z materials.

Transverse effects in the production of x rays with a free-electron laser based on an optical undulator

The interaction between high-brilliance electron beams and counterpropagating laser pulses produces x rays via Thomson backscattering. If the laser source is long and intense enough, the electrons of the beam can bunch on the scale of the emitted x-ray wavelength and a regime of collective effects can establish. In this case of dominating collective effects, the FEL instability can develop and the system behaves like a free-electron laser based on an optical undulator. Coherent x rays can be irradiated, with a bandwidth very much thinner than that of the corresponding incoherent emission. The emittance of the electron beam and the distribution nonuniformity of the laser energy are the principal quantities that limit the growth of the x-ray signal. In this work we analyze with a 3D code the transverse effects in the emission produced by a relativistic electron beam when it is under the action of an optical laser pulse and the x-ray spectra obtained. The scalings typical of the optical wiggler, characterized by very short gain lengths and overall time durations of the process, make possible considerable emission also in violation of the Pellegrini criterion for static wigglers. A generalized form of this criterion is validated on the basis of the numerical evidence.

“…Existing Thomson sources [22][23][24][25][26][27][28][29][30][31][32] have already demonstrated to be an important tool for generating tunable quasimonochromatic x=γ rays suitable for applications in many fields such as crystallography, plasma, high energy, matter physics and nuclear photonics and in the advanced biomedical imaging. In fact, experiments on phase contrast imaging [25,27], microtomography [25], K-edge techniques [23,33] on biological and human samples have been successfully performed.…”

We analyze the possibility of producing two-color x or γ radiation by Thomson/Compton backscattering between a high intensity laser pulse and a two-energy level electron beam, constituted by a couple of beamlets separated in time and/or energy obtained by a photoinjector with comb laser techniques and linac velocity bunching. The parameters of the Thomson source at SPARC_LAB have been simulated, proposing a set of realistic experiments.
