“…In the present study, the attenuation coefficient was estimated by the extrapolation of data calculated with the NIST Attenuation database [43]. A rough estimation of I λ is possible with data on the MPC radiance B λ [22,25,26] as:…”

“…A photo of the sample placement (for Mo/Si samples) in the chamber is presented in Figure 1. Generation of compressed plasma flows and the radiation fluxes were carried out with a high-current plasma accelerator (MPC) with a coaxial electrode unit 1 [22,25,26]. The electrodes were made from AISI 321 steel.…”

“…The generation of VUV/UV radiation occurs as a result of joint deceleration of the high-velocity plasma flows in a background gas and action of ponderomotive force. This leads to the formation of a high-temperature region (a plasma focus) with a brightness temperature of ≈40-100 kK [25]. Such emitters are characterized by a high brightness and extended dimensions of the emission zone [22].…”

This study discusses the main features of the irradiation of prospective multilayer coatings by VUV/UV radiation from compressed plasma flows. Such radiation is characterized by a broadband spectrum and high brightness fluxes. Oxide and Mo/Si bilayers were used as the basis of the reflective multilayers for the visible and UV ranges. A gas-dynamic response from the irradiated surfaces was studied with schlieren photography. The properties of original and irradiated multilayers were described with ultra violet visible infrared spectroscopy (UV-Vis-IR), X-ray diffraction (XRD), X-ray reflectometry, scanning electron microscopy (SEM) and other techniques. Data on the degradation of optical properties and surface morphology were obtained.

“…These measures allow us to ensure a stability and reproducibility of secondary-standard lamps that is no greater than 4 % per year. For wavelengths shorter than 105 nm, suitable secondary standards are windowless sources such as those based on a discharge with evaporating walls or based on plasma focus [9]. Both sources emit pulsed radiation with a pulse-width of some microseconds in the spectral range 30 nm to 200 nm (powerful continuous radiation spectral radiance of order 10 15 W/m 3 sr to 10 17 W/m 3 sr).…”

The stability and reproducibility of secondary-standard sources and detectors are the main problems and the fundamental trouble of spectroradiometry in the ultraviolet spectral range. The high accuracy of the spectroradiometric unit for primary standards based on synchrotron radiation sources is lost by transferring that unit to unstable or irreproducible secondary standards. The best secondary-standard sources and detectors for units of spectral radiance, irradiance, radiant power and flux for the wavelength range 30 nm to 400 nm are described. Integral radiometers for different applications are presented.

“…The high current emitters based on compressed plasma jets are sources of powerful broadband radiation (with fluxes of ≈10 20 -10 22 photon/s per a single pulse) [1]. Ponderomotive forces lead to formation of a high temperature plasma focus with a brightness temperature of ≈30-100 kK [2]. The maximal spectral brightness lies within the range of ≈30-100 nm.…”
