We propose a novel experimental scheme for a compact and tunable x-ray source capable of producing x-ray pulses as short as few tens of femtoseconds. It is based on the Thomson back scattering of a terawatt femtosecond laser from relativistic plasma-accelerated electrons. Here we present particle-in-cell simulations for the ultrashort e-beam generation from the laser-wakefield accelerator utilizing a plasma density transition and the basic characteristics of x-ray generation. A plan to perform the proposed experiment by using a 20 TW 40 fs laser system is presented. © 2004 American Institute of Physics
