Beam-shape effects in nonlinear Compton and Thomson scattering

Observation of nonlinear effects in Compton scattering.

Nonlinear Compton scattering has been observed in the collision of a low-emittance 46.6-GeV electron beam with terawatt pulses from a Nd:glass laser at 1054 and 527 nm wavelengths in an experiment at the Final Focus Test Beam at SLAC. Peak laser intensities of 1018 Wycm2 have been achieved, corresponding to a value of 0.6 for the parameter h ­ eErmsymv0c. Results are presented for multiphoton C...

Low Intensity Nonlinear Effects in Compton Scattering

The design and optimization of a Mono-Energetic Gamma-Ray (MEGa-Ray) Compton scattering source are presented. A new precision source with up to 2.5 MeV photon energies, enabled by state of the art laser and x-band linac technologies, is currently being built at LLNL. Various aspects of the theoretical design, including dose and brightness optimization, are presented. In particular, while it is ...

Experimental study of nonlinear laser-beam Thomson scattering

We observed 8 10 7 . 1 × X-ray photons/pulse generated through relativistic Thomson scattering between the 14GW CO2 laser and 60MeV electron beam at Brookhaven National Laboratory. Non-linear Thomson scattering can be observed by upgrading peak power density of the CO2 laser. Introduction Development of high-intensity, short-pulse, and compact X-ray sources is demanded for various fields of sci...

Nonlinear Thomson scattering: A tutorial

Recent advances in table-top, ultrahigh intensity lasers have led to significant renewed interest in the classic problem of Thomson scattering. An important current application of these scattering processes is the generation of ultrashort-pulse-duration x rays. In this tutorial, the classical theory of nonlinear Thomson scattering of an electron in an intense laser field is presented. It is fou...
