Abstract
A time-resolved x-ray absorption spectroscopy apparatus on a laboratory scale is being prepared which utilizes a laser plasma as an x-ray source. One of the major aims imposed on this apparatus is to observe x-ray absorption or reflection spectra of various materials in an energy region from 100 eV up to 3 keV. For this purpose, two sets of optical systems are provided, i.e., a toroidal mirror and grazing incidence flat-field grating for the lower-energy region (100-1000 eV), and a toroidal mirror and curved KAP crystal for the higher-energy region (1-3 keV). Detection of x-rays is performed with MCPs for both energy regions. Preliminary experiments on the generation of x-rays have revealed that the intensity of x-rays in the energy region below 300 eV is as high as 10(16) photons/pulse in 2(pi) steradian.
