The secondary emission measured from a material includes all electrons emitted
from the surface. These electrons comprise three groups: (a) true secondaries, (b
) inelastically reflected primaries, and (c) elastically reflected primaries.

Microwave Tube Transmitters
Secondary emission is also an important effect in CFAs and can be exploited in
cold cathode CFAs as the only source of emission (section 7.2.3). When the back
bombarding electrons strike the cathode, they lose energy which is transferred to
...

o Q cc The suppressor grid of a pentode reduces the effects of secondary
emission in the device. This attribute, thus, reduces the requirement to provide a
reverse electron flow path for the screen grid power supply. The screen current ...

When high energy electrons strike a metallic surface they cause emission of
more electrons as shown in Fig. 13.5. Such an electron emission from a metallic
surface by energetic electrons is known as secondary emission. The electrons
that ...

ELECTRICAL AND ELECTRONIC MEASUREMENTS
Both of these method are based on the principle of secondary emission. In
secondary emission, a beam of electrons from an electron gun strikes a target to
emit secondary electrons which are collected by a collector kept at a potential V8.

The three processes that can occur during secondary electron emission: 1)
reflection, 2) backseattering and 3) true secondary emission, are usually treated
as distinct secondary electron yield processes by both electron impacts from solid

Such an emission of electrons is called the secondary emission and the electrons
emitted in this way are called the secondary electrons. The intensity of the
secondary emission, in a particular case, is explained by the “Secondary
