Physical Principles of Electron Microscopy: An Introduction ...
On the other hand, the fact that a voltage comparable to the accelerating voltage
V0 must be applied to an electrostatic lens means that insulation and safety
problems become severe for V0 > 50 kV. Because higher accelerating voltages ...

Principles of Analytical Electron Microscopy
Single- Aperture Lens Probably the simplest type of electrostatic lens is the single
-aperture lens, which consists of a single aperture separating two regions of
different but uniform fields. 2. Cylinder Lens Another straightforward lens is that ...

Handbook of Charged Particle Optics, Second Edition
However, microdischarges affect the function of an electrostatic lens system
because of the local voltage drop on one of the lenses. The high-voltage system
of the EM8 was the most advanced (Schluge, 1954). Nowadays, voltage
fluctuations ...

High Resolution Focused Ion Beams: FIB and its Applications: ...
The Refractive Power of an Electrostatic Lens A lens used for light is made from
some transparent material with an index of refraction greater than unity. A lens for
charged particles consists of an electrostatic (or magnetostatic) field, although it ...

The Electronics Handbook
Figure 28.10 shows a simplified diagram of an electrostatic lens. An electron
emitted at zero velocity enters the V) region and moves in that region at a
constant velocity (because the region has a constant potential). The velocity of
the electron ...

Sub-Half-Micron Lithography for ULSIs
The microcolumn consists of a field-emission cathode, a beam-extraction anode,
an electrostatic lens (EINZEL lens), and an electrostatic deflector (OCTAPOLE).
The field-emission cathode is mounted on a microactuator (STM) which is used ...

Dictionary of Pure and Applied Physics
The force on test charges placed in such a field is given by Coulomb's law.
electrostatic focusing Focusing of the electron beam by use of an electrostatic
lens that varies the electric field. See electrostatic lens. electrostatic hazards

TV and Video Engineering
A modified electrostatic lens arrangement of a tetrode type gun, called an
equipotential lens is more commonly used in most cathode ray tubes. It
comprises three coaxial cylindrical electrodes as shown in Fig. 15.1(c). The inner
electrode is at ...

Scanning Electron Microscopy: Physics of Image Formation and ...
2.12 shows the combination of a conical magnetic lens and an electrostatic lens [
2.53-55]. The latter consists of an inner electrode at the acceleration potential
and an outer electrode at earth UoccO— . Magnetic lens Electrostatic lens ...
