  • Publication number: 20240085357
    Abstract: An electron beam accelerated using a first acceleration voltage is applied to respective positions on a sample to obtain spectra A at the respective positions, and an electron beam accelerated using a second acceleration voltage different from the first acceleration voltage is applied to the respective positions on the sample to obtain spectra B at the respective positions. Then, a spectral ratio A/B of the spectra is calculated at each of the positions to generate a waveform representing the spectral ratio A/B. The value of a spectral ratio A/B in an energy region of interest is extracted from each of the waveforms. The extracted values are mapped onto points corresponding to the respective positions on the sample, whereby a spectral map is generated. The spectral map is displayed.

  • Publication number: 20240051624
    Abstract: On the first diagonal, the member is arranged in cooperation with the subframe and the undercover. Further, the cover front-side connection portion and the cover rear-side connection portion are located on or near the first diagonal line. Further, the undercover is provided with a reinforcing portion extending on a second diagonal line which is a diagonal line of a quadrangle having a cover front side connecting portion and a cover rear side connecting portion as a top portion. Therefore, the rigidity of the frame front connecting portion can be increased. In this structure, since it is not necessary to provide an additional component different from the undercover, it is possible to eliminate an increase in the number of components due to the additional component and an occupation of space due to the additional component.
