Abstract :
Short pulse X-rays were generated by Thomson scattering between a few picosecond electron bunches and 100 fs Ti:Sapphire laser lights in a 90-degree and a head-on interaction configurations. The electron beams (0.5 nC/pulse) with 14 MeV energy were focused to a beam radius of 100 μm (rms). The energy and the pulse duration of the Ti:Sapphire laser used for the scattering experiments, were typically 100 mJ and 100 fs, respectively. The number of the X-ray photons generated at an interaction point was estimated to be 1.4 × 104 and 1.0 ×105 in the 90-degree and the head-on collisions, respectively. The pulse duration of the X-ray was calculated with the measured beam parameters of the electron and the laser beams to be 400 fs and 3 ps (rms) in the 90-degree and the head-on collisions, respectively
