Abstract

CVD mono-crystalline diamond films were employed as detectors of the radiation emitted from the laser-generated plasma obtained with a Nd:Yag laser at the INFN-LNS in Catania (1010 W/cm2) and a high-power iodine PALS laser in Prague (1015 W/cm2). Plasmas were obtained using different targets: Al, Ta, Au, and CF2. The plasma characterization was carried out by the use of diamond detectors and ion collectors placed at different distances and angles with respect to the position of the ablated target. Diamond detectors measure UV, X-rays, electrons and ions. Time-of-flight technique was exploited to separate photon, electron and particle contributions. The TOF diamond spectra were compared with traditional ion collector spectra. The results indicate that the ion energy resolution of diamond detector is high and that the mean energy of soft X-rays could be obtained by analyzing the spectra acquired for different absorber films.
