The project analysis of Undulative Induction Accelerator (EH-accelerator) for the waste and natural water purifica-
tion systems is accomplished. It is shown that the use of the four-channel design of induction block and the standard
set of auxiliary equipment (developed earlier for the Linear Induction Accelerators - LINACs) allow to construct
commercially promising purification systems. A quality analysis of the accelerator is done and the optimal parame-
ters are chosen taking into account the specific sphere of its usage.

1 INTRODUCTION
It is well known that apart from traditional scientific
application the electron accelerators are also widely
used for purely commercial purposes, including defec-
toscopy in mechanical engineering, sterilization of
medicine and foodstuff products etc. [1, 2]. However,
the constructing of purification and disinfecting systems
for waste and natural waters [3, 4] should be noted espe-
cially in view of topicality of this problem for modern
industrial world.
Both: radioactive isotopes as well as the accelerators
are used in the mentioned systems as the sources of ion-
ized irradiation. But, it is obviously that the first of these
ways is not acceptable for widely social application
from the radiation security point of view. On the other
hand, the problem of developing the commercially suit-
able design of an electron accelerator also was rather
topical long time. This can be explained by that the tra-
ditional accelerator designs (which, as a rule, had been
developed in the framework of known nuclear pro-
grams) rather often are found to be unacceptable for
"usual" industrial applications.
We propose to construct the system of the discussed
type on the basis of Undulative Inductional Accelerators
(UNIAC or EH-accelerators) [5-7] as a source of ion-
ized irradiation. This allows to increase considerably the
commercial attractiveness of such purification systems
because of a number of advantages of EH- accelerators,
such as a relative compactness, reliability, efficiency in
work, etc.
Technological and element basis of the EH-accelera-
tors is the same with Linear Inductional Accelerators
(LINACs) [8,9]. But, in contrast to the LINACs the EH-
accelerators are found to be essentially "easier" with re-
spect to technological requirements and commercial
characteristics. The peculiarity of the EH-accelerators of
principle is the use of many accelerative channels,
which are connected by special turning systems like to
[10].

TEM OF WASTE AND NATURAL WATER

tors, which are usually used in purification systems.

gineering system, which consists of a number of design
elements and blocks. Let’s discuss some of most impor-
tant elements and blocks of the EH-accelerator pro-
posed.
The electron gun. In this project it is proposed to use
a standard electron gun of a magnetron type which is
produced in the modern industry. The parameters of the
gun are given in Table 2.
The induction block consists of eight induction sub-
blocks. The arrangement of the eight-channel induction
block is shown in Fig. 1. The parameters of the induc-
tion block are given in Table 3.

tron beam, 3 - the induction channels, 4 - the vacu-
um channel.

The magnetic pulse generator [11] is used as a feed-

is shown in Fig. 2.
Fig. 2. The scheme of the feeding system constructed
on the basis of a magnetic-bunch-generator. Here
the four-cascade scheme is used. Fl is the forming
line. HIT is the high frequency pulse transformer.
D is the thyristor block (commutation block). The
first LC is the circuit with resonance frequency.
The thyristor block is used as a commutation ele-
ment of the system. It allows to make the frequency of
bunch passing as the quantity of order ~10 kHz [15]. To
get the required power we use two pulse generators,
each of them feeds four induction channels. The opera-
tion of the two generators is done from the main master-
ing generator.
The parameters of the feeding system are given in
Tables 4, 5.

Other systems. The vacuum system consists of the for-
vacuum and turbo-molecular pumps for obtaining
10-5-10-6 Pa. The system for electron bunch scanning is
the C-like electromagnet which is driven by the low fre-
quency source of supply, with a frequency of 200 Hz.
3 THE PROJECT CHARACTERISTICS OF
THE SYSTEM FOR PURIFICATION OF
WASTE AND NATURAL WATERS ON THE
BASIS OF THE EH ELECTRON ACCELER-
ATOR
The proposed purification system consists of two
subsystems: mechanical water purification (the first sub-
system) and the subsystem of radiation purification (the
second subsystem). In the case, if it is necessary, the
system may contain three subsystems (plus the subsys-
tem for biological purification) that depends on specific
requirements to the output water quality. The first and
last subsystems are described in detail in the literature.

ly. The general project characteristics of this system are

It is cleared that the water output parameters after
purification and disinfecting, which are given in Ta-
ble 7, could be really attained. Therein, the first column
shows the water parameters, which are entered in the
system for radiation purification and disinfecting after
the mechanical and biological purification. As it is read-
ily seen, the parameters of the proposed system (see Ta-
bles 6, 7) is close to the well-known analogous systems.
However, the proposed variant looks more attractive for
practice owing to a number of its advantages. Including,
relatively small total system dimensions (i.e., the system
could be compact), relatively low work voltage (20 kV
on the inductor and less 1 kV on the feeding system, in
comparison with ~1-2 MV in the traditional systems of
the same class). It should be added also that the EH-ac-
celerators are characterized by the low level of the ex-
ternal electrical fields (i.e. they posses good electromag-
netic compatibility) without decreasing the intensity
within the acceleration channels. All this makes the pro-
posed project very promising for practical application.
It should be mentioned that also the authors had ac-
complished relevant business-analysis of the project.
We have be convinced that the industrial producing the
systems on the basis of EH-accelerators, which are de-
signed for purification and disinfecting of waste and
natural water, could be regarded as a very promising
trend for the investing of capital.
4 CONCLUSION
Thus, as it has been shown above, the systems of a
commercial type can be really constructed on the basis
of EH-accelerators. Therein, the existing level of mod-
ern traditional industrial technologies can provide the
required element basis. It is clear also that such systems
could be interesting from the practical point of view.
