摘要： This disclosure presents systems for x-ray absorption fine structure (XAFS) measurements that have x-ray flux and flux density several orders of magnitude greater than existing compact systems; for applications of x-ray absorption near-edge spectroscopy (XANES) or extended x-ray fine absorption structure (EXFAS) spectroscopy. The higher brightness is achieved using designs for x-ray targets that comprise aligned microstructures of x-ray generating materials fabricated in close thermal contact with a substrate having high thermal conductivity. This allows for bombardment with higher electron density and/or higher energy electrons, leading to greater x-ray brightness and high flux. The high brightness x-ray source is coupled to an x-ray reflecting optical system to collimate the x-rays, and a monochromator, which selects the exposure energy. Absorption spectra of samples using the high flux monochromatic x-rays can be made using standard detection techniques.

摘要： An X-ray generating apparatus includes an electron gun, a target configured to generate X-rays by being irradiated with an electron beam emitted from the electron gun, and a controller configured to control a first mode for thinning the target by irradiating the target with an electron beam with a current adjusted within a first current range and a second mode for generating X-rays by irradiating the target with an electron beam with a current adjusted within a second current range. The first current range has a lower limit larger than an upper limit of the second current range.
