1.1 Transmission electron microscope
The conventional transmission electron microscope (TEM) operates at the usual accelerator voltage of 100 to 300 kV for the study of materials. Higher voltages have been used in the past (up to 3 MV in Toulouse), but it's practically only in Japan that you'll still find equipment operating at 1 to 2 MV.
The TEM gives a global image of a thin object, traversed by fast electrons. The column (figure 1 ) consists of an electron gun, the gas pedal, magnetic lenses (2 or 3) forming the condenser assembly, an objective lens, one or two intermediate lenses, a projection lens (projector) and a chamber for observing and recording...
