    摘要: An electrostatic lens unit (23) for a charged particle beam system includes an insulating sheet (35, 37) having first and second opposite sides (42, 43) and comprising first and second laterally-spaced portions (35, 37). The first insulating sheet portion (37) is arranged to provide a cantilever (25) supporting a tip (26) for nanometre-scale probing of a surface of a sample adjacent the second side of the sheet. The second insulating sheet portion supports first and second electrodes (69, 81) on the first and second sides (42, 43) respectively and has an aperture (41) for allowing passage of a charged particle beam through the electrodes from the first side to the second side of the sheet.

    摘要: A scanning reflection electron diffraction microscope causes a primary electron beam (4) from its electron gun (2) to be reflectively diffracted from a sample (7) and a diffraction pattern to be formed on fluorescent screen (9). An optical lens (10) reduces this diffraction pattern in size and forms its reduced image on a photoelectric surface (11), thereby producing an image-carrying electron beam. Deflected by a deflecting system including a deflecting coil (12) and a condenser coil (13), the image-carrying electron beam is detected by an electron-multiplier (15) such that a diffraction pattern is displayed on a cathode ray tube (19).

    摘要: Provided is an image type electron spin polarimeter. It at least comprises a scattering target, a two-dimensional electron detector and an electron bending unit, wherein the electron bending unit is used for bending the orbit of the incident (scattered) electrons to a first (second) angle to arrive the scattering target (two-dimensional electron detector) with an optimal incident angle, and to transfer the image of the electron intensities from the entrance plane (scattering target) to the scattering target (two-dimensional electron detector) with small aberrations, and to separate the orbits of incident and scattered electrons to increase the degree of freedom of the geometric configuration of each component of the spin polarimeter. At least one of the first and second angles is not 0°, thereby achieving the first transfer of the two-dimensional image of electron intensities on the entrance plane to the scattering target and the second transfer from scattering target to the two-dimensional electron detector respectively with small aberrations, and then achieving multichannel measurements of the electron spin.
