In this paper we demonstrate the polarization control of the Thomson scattering source experimentally. We control the incident laser polarization by rotating a quarter-wave plate, thus controlling X/gama-ray polarization. In order to measure the polarization, we use Compton scattering method. Meanwhile, stokes parameters of X/gama-ray whose energy varies between tens of keV and MeV are simulated. The simulation results show that with the increasing of X-ray Energy, X-ray polarization is a constant value in a small cone of motivation. According to modulation curves analyzed from experiment results, we can get the conclusion that the polarization of Thomson scattering source is tunable and controllable.
