Abstract
1422329 Electron microscopes SOC NATIONALE DES PETROLES D'AQUITAINE 29 Dec 1972 [29 Dec 1971] 60042/72 Heading H1D [Also in Division H5R] In a method of X-ray spectrometric investigation of a sample, in which an extended area of the sample is irradiated with a beam of electrons to excite X-rays, error due to topographic irregularites of the sample surface are reduced by arranging that the angle between the incident electron beam and the X-ray beam selected by the spectrometer collimator does not exceed 40 degrees. As described, the electron source is a glow discharge tube, and may direct a beam normal to the sample surface, the collimator being arranged closely adjacent. Alternatively, the collimator may be directed normal to the surface and be flanked by a pair of electron sources (Fig. 4, not shown), or surrounded by an annular electron source (Fig. 5, not shown); or the electron beam may be deflected to produce normal incidence by a magnetic or electrostatic field (Figs. 3, 12, and 13, not shown); the apparatus employed in these arrangements is as described and claimed in Specification 1,422,330. In a further arrangement, Fig. 14, a sequence of electron sources 2 and collimators 1 are arranged around the surface of a cone, the angle α being less than 40 degrees.
