Abstract
Beams of X-rays of few keV energy have been produced from laser-supersonic gas jet interaction. Betatron X-ray radiation is generated when energetic electrons are accelerated and experience betatron oscillations in the ion channel produced in the wake of a high intensity femtosecond laser pulse. Experiments took place at the 200 TW laser system (5 J, 25 fs, 10 Hz) of the Advanced Laser Light source facility (ALLS). Thanks to the laser system performance these preliminary results are the first steps to an expected improvement of the X-rays beams characteristics (collimation, brightness and energy above the keV range).
