Vacuum
technology is widely used in a variety of industries. Here are
some applications you would have certainly heard about:
I) An early application of vacuum technology came around 1900
when the first major industrial use was for light bulbs and
TV tube production (later on). It has been shown that filaments
emit electrons under vacuum which is the major property used
in television technology.
II) The second major application is in the electronic industry.
Many processes that occur in a semiconductor fabrication facility
require vacuums of different levels, including the deposition
of thin films of material on computer chips.
III) Another major application is in space technology. The
main issue in space technology is how to design the space station
or shuttle in order to maintain a pressurized cabin. Also, it
is important to design safe space-suits to protect astronauts
during their missions in open space.
These are examples of how vacuum technology helps us. Now we
will proceed to learn about vaccum and how it is created and
measured. In order to learn about vacuum, you will first need
to understand the concept of pressure.
With the help of interaction a photon with physical vacuum
on the basis of classical representations is established, that
there are tied charges, composed by electron and positron. On
the basis of the energy equation of photon and deformation the
distance between charges in the tied charge is received. The
limiting deformation of the tied charge for red border of photon
frequency is determined. The dependence of polarization of physical
vacuum on deformation of the tied charge is deduced and some
energy ratios are considered. Is established, that a key role
in all ratios plays of the constant thin structure of radiation
As classical structure of physical vacuum (PV) we shall understand
some structural formations deduced, basically, with the help
of classical physics operation on the help of the Coulomb and
Newton laws. It means, that the consideration of the problem
does not involve relativity (speeds compared to speed of light),
quantum mechanics etc. modern physical theories. The author
is far from opposition of classical and modern representations
and uses the classical approach as the simplified method of
a task with the sole purpose - to receive some simple approach
to a complex and difficult problem.
For penetration into PV structure the phenomenon of "photoeffect"
is used, though there are also other ways in the given direction,
for example, task after Lamb for thin structure of radiation
(1947). Let's consider a photon interaction with PV. For the
decision of a task we shall accept, that PV has some structure.
The story of the vacuum is a thread that runs through much
of physics from that day to this, and as an interesting and
almost subversive concept it has excited scientists and philosophers
from early Greece to the present day, as the articles by Andrew
Gregory and Peter Kalmus in this issue illustrate. The practical
application of vacua underpins much of everyday life, even if
most people think of it as something that keeps the coffee warm,
somehow. The concept of nothing (zero) in mathematics was equally
difficult for mathematicians to accept-but it is sadly outside
the scope of this article.
