The absorption of soft X-rays by gold at density of ≈ 0.01 g/cm3 and temperature of ≈ 20 eV has been measured in the photon energy range of 50 to 300 eV. For that purpose, a thin gold foil tamped by carbon was heated by thermal X-rays generated i

We characterize an x-ray spectrometer in the wavelength range 10–70 A. The instrument has been designed for the study of the soft x-ray emission from plasmas generated with intense sub-ps laser pulses. It uses a flat field reflection grating with 2

An intense soft X-ray pulse of radiation ≈1 TW/cm2 generates in low (less than 50 mg/cm3) density foam nonlinear radiative heat waves, which propagate with a velocity several times higher than the sound velocity. A foam density of 5 mg/cm3 was achi

We present measurements of the samarium $(Z=62)$ $M$-shell absorption band around 11 \AA{} (1.1 keV) at electron temperatures between 5 and 20 eV. Using point projection absorption spectroscopy, we measured the absolute transmission of an x-ray probe

We describe a XUV spectrometer for the study of dense hot microplasmas at wavelengths between ≈50 and ≈300 Å. It uses a commercially fabricated grazing incidence flat-field reflection grating with 1200 grooves per millimeter. The spectral resolu

Gold pinhole transmission gratings fabricated by Heidenhain GmbH primarily for the purpose of studying the radiation of intense soft x-ray sources have been tested with the synchrotron radiation of BESSY. Typical results for the spectral dependence o
