X-ray analysis apparatus and x-ray generation unit
The X-ray analysis apparatus contains an X-ray generation unit. The X-ray generation unit includes a target plate having a target that is irradiated with an electron beam from an electron beam source and generates X-rays, X-ray convergence optics that converges X-rays generated from the target in conjunction with a movement of the target plate, and a driving unit that changes a position of the target plate or the X-ray convergence optics relative to the electron beam source.

Multiple image segmentation and/or multiple dynamic spectral acquisition for material and mineral classification
The invention relates to method and system configured for material analysis and mineralogy. At least one image based on first emission from a sample is provided. First spectra of the sample based on second emissions from the second scan locations of the image are provided. A confidence score is calculated for every first spectrum, and second scan location(s) with confidence score(s) below a threshold value are selected. Second emissions from the selected second scan location(s) are acquired to provide new image and determine new second scan locations within the respective new image.
Electron microscopy analysis method
The present disclosure concerns an electron microscopy method, including the emission of a precessing electron beam and the acquisition, at least partly simultaneous, of an electron diffraction pattern and of intensity values of X rays.

Sample analysis apparatus and method
Spectrums are measured by irradiating an electron beam on a sample while varying an accelerating potential and by detecting X-rays emitted from the sample. A normalizer unit normalizes the spectrums and thereby calculates normalized spectrums. A difference calculator unit calculates difference spectrums based on the normalized spectrums. A search unit performs a search in a database for each comparison difference spectrum, and identifies compounds contained in the sample.
