摘　　要：X-ray spectra of H-like and He-like aluminum ions from aluminum buried in CH layers irradiated with 30fs, 200 TW laser are measured. The electron temperature and density are derived from line ratios of the He-α resonance line to its satellite lines. Typical temperatures of 490-646 eV and electron densities up to 7 × 10^20 cm-3 are obtained. The results show that the electron density increases and temperature decreases with the increasing CH thickness.X-ray spectra of H-like and He-like aluminum ions from aluminum buried in CH layers irradiated with 30fs, 200 TW laser are measured.
