electron bombardment

Such energy may be provided by heat, electron bombardment, or light.

The two most common irradiation methods are neutron and electron bombardment.

Neither substrate temperature nor electron bombardment appear to have a major effect on the film structure.

Electron bombardment can be used to modify the properties of zinc-phosphide films.

Intense electron bombardment of the phosphor layer will also release gas during use.

Sample heating can be accomplished by electron bombardment or thermal radiation.

The initial excitation may be due to either X-ray or electron bombardment, although we concentrate on the former.

The vacancies are produced by electron bombardment and annealing to extremely high temperatures.

Electron bombardment ionization sources; Collector system suitable for isotopic analysis.

Fluorescence is observed in the atmosphere when the air is under energetic electron bombardment.

Davisson began work in 1921 to study electron bombardment and secondary electron emissions.

Television glass plates are subject to electron bombardment, which tends to darken them by creation of F-center color centers.

In a similar process, the electron bombardment of the metal both extracts and excites electrons inside the metal.

The primary effect of electron bombardment appears to be the creation of preferred nucleation sites on the substrate.

Electron bombardment ionization sources; 4.

For electron bombardment, the sample holder is equipped with a filament which emits electrons when biased at a high negative potential.

The effects of substrate temperature and low-energy (0.5–2 keV) electron bombardment of the film during growth have also been studied.

After concluding that a Von Ardenne source was insufficient, he developed the electron bombardment source in 1958/59.

But occasionally, for reasons unknown, though possibly connected with electron bombardments from space, the dust becomes electrically charged and each particle repels its neighbors.

As discussed in connection with a scintillator detector, some materials emit visible light in response to electron bombardment (cathodoluminescence).

Electrons from the photocathode are accelerated and focused electronically out on the output phosphor which emits light as a result of electron bombardment.

Propellant atoms are injected into the discharge chamber and are ionized by electron bombardment, forming a plasma.

The most commonly used detector setup is an electron bombardment ion source followed by a mass filter and an electron multiplier.

The radicals, together with other reaction products, are permitted to enter the ionization chamber of a mass spectrometer and are subjected to electron bombardment.

It consists of a metal plate coated with a thin layer of powder which fluoresces (emits light) under electron bombardment.
