Isabelle Moulinier is a research scientist at Thomson Reuters corporate R&D group. Since joining the group 15 years ago, her research interests have focuses on the application of information retrieval, natural language processing and machine learning technologies to the improvement of search and other aspects of the user experience. Prior to joining Thomson Reuters, she worked on text categoriz...

We will follow Ch. 6 in Weinberg’s book quite closely. As seen therein, the exact calculations for the evolution of radiation perturbations require that we take into account the fact that Thomson scattering of photons depends on the photon polarization. To simplify and get to the basic physics results, we will assume that photons are unpolarized and that Thomson scattering is insensitive to pol...

Inverse Compton scattering sources are finding increasing use as intense of high-energy photons. When operated at high field strength, ponderomotive detuning the scattered emission can lead to decreased source performance. Up now, calculations spectra for such nonlinear Thomson have been done assuming a perfectly aligned electron interacts with incident laser beam and several authors investigat...
