1. INTRODUCTION
Since 1970, BINP SB RAS has been developing and
manufacturing the ILU-type electron accelerators for
the work in the research and industrial radiation-techno-
logical installations. The design and schematic solutions
of the installations envisage a continuous round-the-
clock operation under conditions of industrial produc-
tion.
The ILU-type accelerators cover the energy range
from 0.7 to 5 MeV at an accelerated beam power of up
to 50 kW. The intrinsic features of these accelerators
are the simple design, ease in maintenance and the long
term reliable operation under conditions of industrial
production. Table shows the basic parameters of the
ILU-type accelerators produced by BINP [1-3].

2. GENERAL DESCRIPTION
The basic model of the ILU family is the ILU-6 ac-
celerator [1]. The model ILU-6 is widely used in our
country and abroad. This accelerator has rather good
parameters at modest dimensions and can be used for
wide spectrum of technological processes.
The basic unit of the ILU-6 accelerator is a toroidal
copper cavity. It has axial protrusions forming the ac-
celerating gap. The protrusion shape was chosen to
form and focus the electron beam so that its injection,
acceleration and further passage through the extraction
system were performed with minimum losses.
The cavity (1) is placed into the vacuum tank (2)
(Fig.1). The electron injector (4) is formed by the cath-
ode unit and the grid mounted in the upper protrusion.
The lower electrode and injector form a triode acceler-
ating system.
Fig.1 ILU-6 accelerator
Under the lower electrode of the cavity there is a
magnetic lens shaping an electron beam in the acceler-
ator channel and the extraction device 6.
RF self-exciting generator (3) based on powerful tri-
ode type GI-50A is installed directly on the vacuum
tank. Generator assembled according to the common
grid circuit is working at frequency about 116 MHz,
that is near the specific frequency of the cavity. Anode
circuits are coupled to cavity through the inductance
loops. The coupling rate is determined by the square of
loop and the tuning of the anode circuits. The generator
feedback is provided by the additional capacitance
made in the form of a disk, inserted between the tube’s
anode and cathode. The value of capacitance is about
20 pF. The fine tuning of the feedback value and its
phase is made by the cathode short-circuited tail with a

movable shortcut contact moved by a servo-motor. The
coupling rate of generator with cavity is tuned during
the accelerator’s preliminary adjustment by varying the
capacity of the vacuum capacitor (8) and the coupling
loop square by varying the position of its support (7).
The cavity is placed into the vacuum tank made of
stainless steel. The high vacuum pumping is done by four
spallation pumps placed at the top and bottom plates of
the tank. The forevacuum pumping is provided by the
forevacuum aggregate through the nitrogen trap. All the
sealings in the vacuum tank are made of metal (copper
and indium). The operating vacuum is of 10-6 Torr. In the
normal operation of the accelerator intervals of about
two days do not require the forevacuum pumping for
switching on the spallation pumps.
Fig.2. ILU-8 accelerator
Main parameters of the cavity of ILU–6 accelerator
are: diameter – 1000 mm, height – 820 mm, resonance
frequency – 116.3 MHz, accelerating gap length –
120 mm, Q-factor – 19.4×103, shunt impedance–
3.5 MOhm. Pulse operating mode as following: pulse
duration – 400…500 µs, maximum pulse repetition –
50 Hz.
The compact electron accelerator ILU-8 (Fig.2) was
built on the base of ILU-6. The technology process of
irradiation of tube and wire features was taken in ac-
count during this construction.
This accelerator does not require construction of a
special protected premise (hall) and can be placed in
usual industrial shop. It can work inside the local biolo-
gical shielding. The local shielding (9) of the accelerat-
or is a kind of a box made of steel plates. This box is di-
vided into two parts. The top part is used to place the
accelerating system with RF-cavity (4), spallation vacu-
um pumps and forevacuum system. The beam extrac-
tion device (5), air pipes of ventilation system and tech-
nological equipment are placed in the lower part of the
shielding. The back wall of the shielding has the chan-
nels (labyrinths) for input of cables, air and water pipes.
The removable front wall serves as a door of a protect-
ive box. The thickness of radiation shielding in side
walls part is 330 mm and in top is 240 mm. Gross
weight of shielding is 76 tons.
The cavity excitation is produced by a one-stage
self-excited generator with the GI-50A type triode. A
feed-back connection (2) through the cavity with a
trombon type phase inverter (10) is used. This generator
is located out of the local shielding. It is connected with
the cavity by a co-axial feeder (1).
Main parameters of cavity resonator of ILU-8 accel-
erator are: diameter – 700 mm, height – 324 mm, reson-
ance frequency – 176.2 MHz, accelerating gap length –
36 mm, Q-factor – 24×103, shunt impedance –
2.7 MOhm. Pulse operating mode as following: pulse
duration – 800 µs, maximum pulse repetition – 60 Hz.

toroidal cavity; 3 – magnetic lens; 4 – ion pumps;
5 - grid-cathode unit; 6 – beam extraction device with
linear scanning; 7– coupling loop support; 8 – vacuum
capacitor; 9 – RF generators
The next development is the ILU-10 accelerator
(Fig.3) based also on the ILU-6 accelerator. It was de-
veloped to work at energy of 5 MeV required for some
technological processes.
In order to decrease high-frequency losses at the
same with the ILU-6 resonator resonance frequency, the
accelerating gap length and total dimensions of the res-
onator were increased. The electron accelerator of ILU-
10 type has two high-frequency generators of ILU-6
type, which operate in parallel for increasing of elec-
tron beam power.
The main parameters of cavity of ILU-10 accelera-
tor are: diameter – 1000 mm, height – 1300 mm, reso-
nance frequency – 115.9 MHz, accelerating gap length
– 270 mm, Q-factor – 28×103, shunt impedance –
8 MOhm.
3. BEAM INJECTION
As mentioned above, the use of the internal injection,
when the cathode with the control grid is placed directly
at the accelerating gap entrance, is the ILU-type accel-
erator’s feature. The opposite electrode of the cavity ac-
celeration gap is used as an anode.
The grid-cathode unit is located on the upper elec-
trode directly at the accelerating gap entrance (Fig.2).
The triode gun consists of the cathode, control grid and
166
lower accelerating gap electrode performing the role of
the anode. The grid and upper electrode are the united
peace made of copper. The cathode unit is installed on
the insulator ahead of the grid. The 16 mm diameter
cathode tablet is made of lanthanum hexaboride (LaB6).
The cathode heating is provided by a cone helix heater
made of tungsten wire of 0.6 mm diameter heated by
current of 20 A, the working voltage being 12…15 V.
The anode hole has 30 mm diameter. A magnetic lens is
installed under the lower electrode allowing the beam
transverse size at the output device entrance to be con-
trolled. In this injection method the beam current is
formed by RF field penetrating into the grid-cathode
gap from the accelerating gap and is determined by the
grid penetration factor.
4. ELECTRON BEAM EXTRACTION
The pulse nature of an electron beam generated by
ILU machines permits designing of beam extraction de-
vices for radiation technologies forming the irradiation
zones for multilateral irradiation of objects of various
forms. It enables one to increase the beam usage effi-
ciency and in some cases to reduce the electron energy
required for irradiation, or to expand the nomenclature
of treated products.
The beam extraction device for extraction of elec-
trons into air is attached to the vacuum tank's lower
flange through a separating valve. The electron beam
extracted into the air through foil. Usually, three types
beam extraction device can be used: linear scanning
device for treatment of flat product, 3-window extrac-
tion device for 4-side tube or cable irradiation [4] and
beam extraction device with X-ray converter [5].
In the linear scanning device each pulse of the beam
is scanned along the length of extraction window
(Fig.1). In the 3-window extraction device beam pulses
are scanned sequentially along its upper windows and
along the left and right parts of lower window (Fig.2).
5. CONCLUSIONS
The important directions in activities of Institute of
Nuclear Physics are medical, biological, and pharmaco-
logical applications of our accelerators. The electron
beam sterilization technology for disposal medical
products is well studied and widely used in our country
and abroad. This technology was developed as an alter-
native to the gamma irradiation by the installations with
Co and Cs isotopes. The ILU-10 accelerator can work
with maximum energy of 5 MeV, ideally suites for the
irradiation centres purposed for treatment of wide spec-
trum of goods. The electron energy of 5 MeV permits to
treat the products that can have the surface density up to
4 g/cm2 if the two-sided irradiation is organized. It
means that the products can be treated in the packed
form – in the cartoon boxes containing the several sets
of products.
The maximum beam power of ILU-10 accelerator is
50 kW, so the productive rate of the irradiation facility
can be up to 300…700 kg per hour assuming the steril-
ization dose of 25 kGy.
It is need to say, more than 30 ILU-type accelerators
were produced and delivered to the different organiza-
tions and industrial plants in Russia, Ukraine, Belarus,
Poland, Czech Republic, Hungary, Italy, Romania, Ja-
pan, China, South Korea, India and Cuba.
