THE BEAM DIAGNOSTIC SYSTEM AT THE RADIATIVE-
TECHNOLOGICAL FACILITY WITH LINEAR ELECTRON
ACCELERATOR
V.I. Sakhno
SC “INR” of the National Academy of Sciences of Ukraine, Kyiv
The main purpose of the production technology
is the receiving the materials (production) with specific
properties. The radiative technologies belong to the
science intensive ones and allow to realize processes,
which depend on the exact numerous parameters and
ensure the stable production characteristics. The modern
radiation technologies engage thin effects of the
substance transformation to the manufacture and allow
to create unique production.
During development of new radiation production
processes, the exactness of parameters monitoring of the
irradiation is the defining moment, and accordingly –
the choice of methods and means of measurement of
beam characteristics. The comparison of beam
(irradiation) parameters with effects of raw material
modification observed is the main purpose of the
technological researches and development. Therefore,
during development of the new radiative-technological
complex based on the electron accelerator at the
Institute for Nuclear Research, Nat. Ac. Scie. of
Ukraine, the particular attention was given just to the
diagnostics system engineering of the beam, which is
designed for irradiation objects.
The development of the diagnostics methods and
technique was performed with regard to the experience
of scientific researches at the INR, and also features and
design parameters of the beam linear electron
accelerator "Electronics U-003" [1]. For convenience of
using it was decided to construct this unit as a separate
device located just behind the exhaust window of the
accelerator in front of the deflection or scanning system.
After analysis of different diagnostic methods [2, 3, 4]
for development of the unit of beam diagnostics we
applied the most simple induction methods and tools,
which ensure the necessary exactness of measurements
with minimum expenditure for the beam of typical
intensities.
The diagnostic unit is constructed with the so-
called signal electrodes.
Taking into consideration the real needs of the
technological processes of the biomaterials and food
products processing, the more sensitive device for the
linear accelerator was created on their basis. The device
includes the intensity beam sensor, two-coordinate
sensor of the beam center position (Fig. 1), and
protective electrodes. The increase of the exactness and
reduction of the distortions is ensured by using in all
measurement contours the differential methods of the
information receiving and processing and sensors design
features.
The two-level beam monitoring system is
foreseen. The first (lower) level is based on the
principles of analog information processing, where,
except own functions of the information receiving, the
independent analog contours of beam stabilization on
the target are created. The further signal processing for
receiving the summarized information on the irradiation
parameters is realized by means of the computer
facilities and nuclear electronics engineering.
The sensors are constructed as one unit, Fig. 2,
which works reliably under the average beam current
ranging from 1 mkA to 10 ìA. Having the aperture of
100 mm in the diameter the device ensures the
sensitivity on the beam center position about 1 mm.
During the measurement of the average current value
the sensitivity of the device does not concede to that of
the typical sensor of the beam linear accelerator
"Electronics U-005". It is expected to use in future such
type of devices for applied works at other accelerators,
with more complicated transportation system (transport
channel) of the beam to the target. As a rule, in this case
the beam monitoring system in many points of its way

through the ionic optics elements of the transport
channel is used. Such systems are expensive and
inexpedient for the applied accelerators, because they
increase the cost of the facility and the cost price of the
radiation technologies. Thereforeit is desirable to draw
perfect methods of the information receiving and
processing.
For the beam diagnostics systems in the
complicated transport channels the special software with
utilization of beam behavior modelling principles during
the passing of the magnetic optics elements of the
channel has been created. The main information for
such system are the beam data at the input, and also in a
monitoring point of the transport channel. This
information is received by 2-3 of the indicated devices.
Further, taking into consideration the elements of ionic
optics modes, by the mathematical information
processing, the beam envelopes on the whole way of its
passing are calculated and reflected. The operator gets
this information on the screen as the combined vertical
and horizontal envelopes (Fig. 3) such, as if
measurements are carried out in many points of the
transport channel. It allows one to simplify the structure
of system and reduce the volume of measurement tools.
