摘要: Laser to x-ray conversion efficiencies from solid targets irradiated by KrF laser pulses of wavelength 248 nm are measured. A 16-bit front illuminated open electrode 1024×256 pixel CCD camera working in single photon counting mode is used record the output Al, Cl, Ag, and Ti emitting 1.5-4.5 keV energy range. X-ray up values ~0.2{%} (2π sr)-1 obtained with duration 2 ps irradiating at 12 Hz peak irradiance 1.9×1016 W cm-2.
