Sentence examples for an electron lens from inspiring English sources

Computed results are presented for an electron lens with superimposed magnetic and electrostatic fields.

His first breakthrough was learning that a magnetic coil could act as a lens for electrons, and that such an electron lens could be used to obtain an image of an object irradiated with electrons.

A number of image intensifiers and converters, particularly for X-ray or infrared radiation, which have appeared since World War II, embody a radiation detector at one end of a vacuum tube and an electron lens inside the tube to relay the image on to a phosphor screen at the other end.

Nevertheless, our simulations capture the appearance of a central bright spot at t = 20 min which reflects the crater acting as an electron lens and focussing the electrons to a caustic (Fig. 7).

Fig. 7 The family of electron rays simulated in the MEM system of Fig. 1, incident on the ( t=20 ) min surface as shown in Fig. 5. a Electron paths close to the surface demonstrate how the surface can act as an electron lens to focus the electrons in the returning beam.

The high order time-of-flight (TOF) aberrations in a practical electrostatic electron lens are calculated using the differential algebraic (DA) method.

In 1931 he built the first electron lens, an electromagnet that could focus a beam of electrons just as a lens focuses a beam of light.

The instrument described previously by Cosslett and Nixon1 4 was limited to a resolution of 0.5µ due to astigmatism in the electron lens and to electron scattering in the metal target.
