Abstract

1338208 Particle spectrometers PHYSICAL ELECTRONICS INDUSTRIES Inc 4 Aug 1972 [27 Aug 1971] 36596/72 Heading H1D A particle spectrometer for analysing electrons emitted from a specimen 23 comprises two coaxial cylinders 11, 12 between which an electric field is established so that electrons of a certain energy will follow a trajectory 25 through gauze windows 16, 17 an apertured plate 35 and then through further gauge windows 18, 19 to a detector at 42, the input of the analyzer being provided with retarding grids 22, 21 which form parts of concentric spheres centred on a point on the specimen 23 and between which there is a radial retarding field. The effect of the first section of the analyser is to create an artificial point source at the aperture 37 in plate 5. An aperture-plate 39 immediately in front of the detector has a slit in the form of segments of an annulus. The cylinders 11, 12 are spaced by discs 13, 14 which are constructed as described in Specification 1,338,209. The analyser is surrounded by a magnetic shield 15 of Mumetal (Registered Trade Mark). In Fig. 6 (not shown) there is a block diagram of an operating system for the spectrometer in which the potentials of the cylinders 11, 12 and grids 21, 22 are varied to scan the energy spectrum of the electrons while measuring the output and plotting the spectrum on an X-Y recorder.
