Calculation of Thomson scattering of intense lasers from electron beams atdifferent interaction angles

Recently there has been considerable interest in the Thomson scattering of intense laser from relativistic electron beams, and a new kind of x-ray sou rce named laser synchrotron source (LSS) has been discussed based on this m echanism which is expected to have extremely good performances. In order to verify this theory, an experiment is going to be carried out by our group using a frequency-doubled yttrium-aluminum-garnet laser and a 25 MeV electr on beam generated by the accelerator in the Applied Department of the Insti tute of High-Energy Physics. In this article some theoretical results have been calculated for this experiment, including the scattered x-ray's wavele ngth and intensity distribution. The results at 180 degrees and 90 degrees have been given and the 180 degrees result should be very close to the expe rimental geometry of 178.5 degrees. In Sec. III, figures of the spatial dis tribution of x-ray are drawn. The future of LSS is prospected finally in Se c. IV. (C) 1998 American Institute of Physics. [S0034-6748(98)01612-8].
