Abstract: A cylindrical mirror analyzer is described having apparatus for quickly and accurately positioning the area of a sample to be investigated at the proper position for analysis. The cylindrical analyzer includes a pair of coaxial and radially spaced apart cylinders and suitable mechanism for supporting a sample to be investigated on their common axis. Means are provided for forming in the space between the cylinders a charged particle deflecting field which will deflect towards the inner cylinder any charged particles within such space which have issued from the sample. Slots in the inner cylinder define a path for the passage of particles from the sample into the space between the cylinders for deflection and then back through the inner cylinder to the cylindrical axis where such particles are collected for analysis of their energy. A screen of fluorescent material is disposed at a location at which it will be activated by particles issuing from the sample because of the bombardment, and a shield is disposed between the fluorescent screen and the sample to project an unactivated or shadow area on the screen. The positional relationship of the shadow on the screen is indicative of the coordinate position of the area on the sample from which the radiation is emitted and, hence, is indicative of the location of the area under investigation.

Abstract: A retarded field electron diffraction spectrometer is disclosed which includes an electron gun for directing substantially monoenergetic electrons onto the surface to be examined of a target to produce scattered electrons from such surface. A spherical retarding grid structure is concentrically disposed of the target in the space between the target electrode and a concentric spherical fluorescent screen. A retarding potential applied to the retarding grid permits only those target scattered electrons having a potential greater than the potential of the retarding electrode to reach the fluorescent screen. The retarding grid electrode has grid openings defining electron passageways having a characteristic diameter less than three times the characteristic length thereof to improve the uniformity of the retarding field. A spherical shield grid electrode is concentrically disposed of and has a radius within the range of 0.3 to 0.8 of that of the retarding grid to enhance the resolution of the spectrometer.
