Abstract

<p>We developed two new soft X-ray absorption spectrometers: one is a laboratory scale ultra soft X-ray absorption(USXA) spectrometer for measuring ultra soft X-ray absorption spectra (50-150 eV) of solid samples such as battery materials, soil and rock and the other is a soft X-ray absorption spectrometric apparatus for measuring soft X-ray absorption spectra (50-1500 eV) of solution samples such as electrolyte solution, wet soil, and living specimen of animals and plants at the BL-12 of Kyushu Synchrotron Light Research Center, Japan. The former spectrometer consists of four sub-systems: (i) a laser and focusing optics; (ii) target and target chamber; (iii) monochromator; and (iv) detector system and sample chamber. We examine the Li-K XANES spectral measurements of lithium halides using the USXA spectrometer. The latter spectrometer has 7 kinds of movable axes and enables to perform the soft X-ray absorption measurements with a fluorescent mode under atmospheric pressure. We carried out the measurements of soft X-ray absorption spectra for varying concentration in aqueous solutions of sodium chloride and magnesium chloride. The obtained experimental XANES spectra are analyzed using the theoretically calculated spectra from the DV-Xα method.</p>
