Abstract:The influence of the conditions of laser initiation on soft X-rays emission of vacuum spark E D Vovchenko and A P Melekhov -The spectrum simulation of the soft X-ray for vacuum spark with laser initiation A P Melekhov and E D Vovchenko Corresponding author e-mail: apmelekhov@mephi.ruAbstract. At a certain form of broadband source soft X-ray spectrum is expected to achieve selective radiation exposure to one of the elements of a multi-component material Cd x Hg 1-x Te. In this case we can talk about a change of… Show more
“…in the energy range 0.6 keV has been under way. These sources are used in nano-lithography [8][9][10][11], surface analysis and modification [12][13][14][15][16] and SXR microscopy in the water window [17][18][19][20].…”
The x-ray spectra of plasma radiation in the wavelength range 30-300 Å are studied. The radiation is emitted from plasma of a vacuum discharge with storage energy less than 30 J that is initiated on an Al or Fe cathode by beam from neodymium laser with a power density up to 10 12 W cm −2 . It is shown that both the spectral composition and intensity of radiation of hot micropinch plasma that is formed in the cathodic jet are determined by the set of the discharge and the laser pulse characteristics. By optimizing these characteristics, a mode of the discharge operation is attainable, in which a significant portion of the radiation energy is located in the long-wave band of the quasi-continuum (230-270 Å and 160-200 Å for Al and Fe cathodes, respectively). That makes it possible to treat such a discharge as an intense source of narrowband soft x-ray radiation.
