A large-scale, double-stream gas puff target has been illuminated by sub-kJ, near-infrared (NIR) focused laser pulses at the PALS facility (Prague Asterix Laser System) to produce high-energy pulses of soft X rays from hot, dense plasma. The double-puff arrangement ensures high gas density and conversion efficiency from NIR to X rays approaching that… (More)

A high-resolution CCD X-ray camera based on YAG:Ce or LuAG:Ce thin scintillators is presented. The high resolution in low energy X-ray radiation is quantified with several test objects. The achieved spatial resolution of the images is <1 microm. The objects used for imaging are grids and small animals with parts of several microns in extent. The… (More)
In this paper we present the results of investigations of a wide band soft X-ray source and a lobster eye optic specially designed for collecting radiation of the source. Soft X-rays in the wavelength range from about 3 nm to 20 nm were produced as a result of irradiation of a double-stream gas puff target with laser pulses of energy 0.8 J and time duration… (More)
We report on recent progress with development of astronomical X-ray optics based on bent Si wafers. Recent efforts with Si wafers have been focused on new forming technologies such as method of deposition of thin layers. The role of substrates quality in performance of final mirror arrays, as required by large future space X-ray astronomy experiments was… (More)
