1. INTRODUCTION
According to increasing search for alternative energy
sources, experiments of studying the problem of
controlled thermonuclear fusion (CTF) carried out on
experimental physical devices such as stellarators and
tokamaks are becoming increasingly important in the
world's major research centers throughout the world. An
integral part of these works is development of automated
systems for collecting experimental data. Traditionally,
much attention is paid to the development of such systems
in Russia, in particular - Institute of Nuclear Fusion,
Russian Research Centre "Kurchatov Institute" (tokamak
T-10) [1], Troitsk Institute for Innovation and Fusion
Research (tokamak FTU) [2], Tomsk Polytechnic
University (tokamak KTM) [3].
Similar research work on the automation of physical
experiments is carried out for torsatron Uragan-2M at the
Institute of Plasma Physics (IPP) of the National Science
Centre "Kharkov Institute of Physics and Technology".
Data acquisition system is an important device due to the
following requirements: significant energy consumption
of the device and auxiliary systems, large amount of
information, pulsing unit (operating pulse – 100 ms, pulse
pause – several minutes), the need to send signals over
long distances from the installation (in accordance with
safety requirements), on-line processing of recorded
information and its visualization and storage.
The main aim of the present activity was to optimize
the time necessary to collect maximum amount of
information, presentation of results and modernization of
data processing algorithms for data acquisition system.
2. EXPERIMENTAL EQUIPMENT
AND SOFTWARE
Uragan-2M experimental thermonuclear device is a
huge and complicated electro-technical device used for
investigation of high-temperature plasma. The input
power rate riches about 1 MW and magnetic field is up to
2 T, current in the windings of the magnetic system is up
to several thousands amperes. Diagnostic equipment
operates in conditions of high electric, magnetic and high-
frequency fields. On the Uragan-2M the following basic
methods of plasma diagnostics are used:
- radiometry (6 channels);
- 1 mm interferometer (3 channels);
- 8–16 mm interferometer - reflectometer (4 channels);
- analyzer of neutral charge (2 channels );
- bolometer (6 channels);
- grid analyzer (32 channels),;
- Langmuir probes (8 channels);
- diamagnetic diagnostics (4 channels);
- RF probes (4 channels);
- capacitive probes (4 channels).
Each diagnostics includes measuring channels
contained sensors, electronic components, signal
transmission path from corresponding diagnostics to
individual workplace. One should solve several problems
connected with amplification, normalization and
protection from strong electric, magnetic and high
frequency noise source signals as well as recording
signals bearing information on plasma parameters in the
installation and operation modes of different systems. The
distance between the diagnostic sensors mounted on the
diagnostic equipment installation and the measuring room
is 100 m.
The automation system is built in the form of a
distributed local area network (LAN) - based hardware-
software complex contained a number of personal
computers equipped with multifunction I/O devices of the
analog and digital signals (see Figure below). The
collection system components are located on several
floors of the IPP, including the premises of the
diagnostical hall, experimental hall "Uragan-2M", server
and storage rooms.
The hardware part of the complex consists of
boards L-783, E20-10 and E14-140 modules of L-Card
production, with the Lgraph2 software, which allows the
input-output information on the analog channels in
various modes [4], as well as microcontrollers
PIC18F2550 (PIC-Programmable Interface Controller) of
Microchip Inc. company [5], integrated into the overall
system via USB and RS-485. Multi-board L-783 can also
perform certain management functions, providing multi-
output of digital and analog signals in accordance with
design software.

Data acquisition system for Uragan-2M
This feature is implemented by the authors on the
Uragan-2M by remote control drives of the measuring
probe [6].
Automated system for collecting diagnostic
information (see the Figure) consists of server and seven
client stations, six of which are equipped with universal
I/O boards L-Card L-783 (3 MHz, 32 channels, PCI), and
one - with the additional modules E20-10 (10 MHz,
4 channels, USB), E14-140 (100 kHz, 32 channels, USB)
and PIC18F2550 microcontrollers for converting analog
input signals, their memorization and analysis at the local
work place of a diagnostician.
The system which is a local area network
"Diagnostics U-2M" also includes computers and
monitors to ensure rapid graphical representation of the
recorded experimental data, the workstation of an
administrator, remote (issued in the experimental hall)
stand - the hub and the data depository. The latter allows
access for users of IPP (Institute of Plasma Physics) local
network to archive recorded experimental data. Stand-hub
includes a computer equipped with boards and modules of
the signals input-output. It is possible to increase the
number of connected channels.
All electrical signals from sensors installed are going
through pre-amplification, normalization (N) and
harmonization. These operations are carried out by so-
called communication devices with the object (CDO),
made in the form of modules in the CAMAC standard and
constructively placed in crates or in a rack. The problem
of high electrical isolation between the electrical signals
from the plant and input circuits of the recording
equipment of automated collection system is solved by
using an optical transmission medium of information
through the use of fiber - optic communication lines (OF),
optical converters and optic-isolation of individual
devices. This ensures a high level of accuracy and noise
immunity which is especially important when using
equipment with remote sensors and extended lines of
communication. The synchronization module ensures the
simultaneous launch of the analog-digital converters on
all diagnostic computers on the arrival of sync pulse (SS)
from the synchronization system of the installation.
The software is implemented in the language of
object-oriented programming such as C++ Builder 6 and
C18 language and provides collecting, displaying and
archiving of the experimental data on a remote server. An
automated system of open architecture allows to extend
the LAN client stations. The software (SW) has a modular
structure and based on high-level C Builder 6 and C18
languages. The last one is a special version of the C
++
language for programming microcontrollers of PIC18
series. This software comprises of autonomous modules
united by joint-manager and general data files. Such a
structure of package provides a complete separation of
functions between the modules which is convenient for
editing and replacement of individual modules. The
program modules are running under Windows XP
operating system and management of this system as a
whole is possible due to Windows Server 2003
specialized software on the server. Up to 1GB of data can
be transferred on one workplace per shift depending on
number of connected channels, time of measurement and
sampling frequency. Multiplayer mode is achieved by
using several parallel processes with full synchronization
of all client stations and server. Parallel processing of
multiple information streams provided real-time data
controlling and viewing with their following storage on a
hard disk.

3. CONCLUSIONS
The data acquisition system for Uragan-2M allowed
to increase data collection, accuracy and reliability of the
experiment. Using the parallel processes with full
synchronization of all customers reduces the time
necessary for data collection and also ensures the
objectivity and reliability of the performed measurements.
Implementation of this system into practice of physical
experiments on the Uragan-2M provided technical
possibility to gain remote access to equipment located at a
certain safe distance from the researcher providing
protection from high electric, magnetic and RF fields.
Minimization of distortion of transmitted signals became
possible due to reducing the distance between the signal
source and conversion devices by integrating low-cost
microcontrollers into the system.
