The Software ModeRTL for Simulation of Radiation Processes in Electron Beam Technologies
Abstract
At present time the electron beam (EB) processing
are widely used in different
industrial radiation technologies. The success of
application of electron beams in radiation
technology depends largely on development of computer
software to be used for simulation of
irradiation process on radiation technological lines (RTL)
incorporating an electron accelerator
with a scanner of electron beam and a conveyor.
The software ModeRTL (Modeling of
Radiation-Technological Line) was developed
by authors for simulation of radiation processes, that
used as an irradiation source of the
pulsed or continuous type of electron accelerators with
electron energy in the range from
0.1 to 20 MeV. The ModeRTL is intended for: a choice
of optimum layout of the radiation
equipment at realization of specific
radiation-technological process; an optimization of
parameters of radiation treatment of objects in view of
features of radiation-technological
process; a validation of the chosen parameters. For
searching optimum solutions, the
ModeRTL calculates and represents the spatial
distributions of an absorbed electron dose,
charge and temperature in an irradiated object, maximum,
minimum and average values of an
absorbed electron dose, factor of utilization of an
electron beam energy, electron ranges, and
other important characteristics of electron - material
interaction in graphic and tabular forms
of convenient for comparative analysis.
The software ModeRTL is a complex of physical and
mathematical methods included
in an uniform program shell. This software uses the Monte
Carlo simulation and calculations
based on analytical model of irradiation processes, gives
an opportunity to compare calculated
results with each other and to compare distributions of
absorbed dose of electrons in different
materials with the world-wide data base. It provides high
verification of calculated results and
decisions accepted on this base.
The ModeRTL program is available for Windows
-98/ME/NT/XP PC' s, has a
convenient user interface which users can use intuitively,
and can be easily adapted to
PC-based control system of any industrial RTL with
scanning electron beams. Results of the
use of the ModeRTL program for optimization of EB
processing parameters in some radiation
technologies will be discussed.
