INTRODUCTION
For the study of the closed magnetic surfaces
structure in the URAGAN-2M torsatron (U-2M) [1] an
automated system was created, providing autocontrol of
the movement of a luminescent rod and as the result – the
measurements of the closed magnetic surfaces was carried
out. Measuring-controlling complex has allowed using
modern, demonstrative method of scanning luminescent
rod [2-4], which passed the approbation on the
URAGAN-3M torsatron [3, 4] earlier and has been
already used on the U-2M torsatron [1]. In persisting
investigations of the vacuum structure of elliptical form of
the magnetic surfaces a remote control of a rod movement
was realized by means of computer and L-783 special
module of the company L-card connected to computer
and an executed complex software on the base of the
object-oriented programming C++Builder 6.
METHOD AND PERFORMING
THE MEASUREMENTS OF THE MAGNETIC
SURFACES
Coated by a saturated solution of luminophore,
grounded a stainless steel rod with a diameter of 2 mm,
(Fig.1, pos. 4) was consolidated on a movable rod with
linear gear in device of the movement and was placed in
the poloidal cross-section of the toroidal vacuum chamber
of U-2M (Fig.1, pos.3 and Fig.2), between solenoids of
the toroidal magnetic field. For full scanning with a rod
(Fig.1, pos.4) of the elliptical cross-section of a vertically
located magnetic surface in the regimes of the magnetic
configurations with different vertical magnetic field a rod
must execute some complex two-dimensional movement
(scanning) - angular (azimuthal) travel with simultaneous
movement along the major radius R of the torus, see
Fig.1. Methodically, when the diameter of the vacuum
chamber equals of 0.68 m and the length of a rod is of
0.44 m, the movement program of the rod was built so
that the main part of it movement formed the angular
scanning. For execution of such movement in toroidal
vacuum chamber with a high vacuum the complex
mechanical in-plane displacement device was created (the
drawing RS.1003 AD, Institute of Plasma Physics, NSC
KIPT) with two micro electric motors - the UAM-74
motor (the alternating voltage is 127 V, the power is 30
W) with the reductor of the RM-09 motor and the RM-09
motor (the alternating voltage - 127 V, the power –
10 W), and two potentiometers for determination of the
location coordinates of the rod (the operation voltage is 5
V). This device can be seen on Fig.3. Movement of the
rod was held by means of the program, installed on
computer, which could switch contact pairs – closed
electrical feed circuit by reed relay in power supply unit
of micro motor and controlled movement of the rod. The
scheme of scaling the sizes on an image consisted of 2
LEDs (Fig.1, pos.5) with the distance between them of
414 mm.
Fig. 1. The poloidal cross-section of the U-2M torsatron
and the cross-section of one of variants of calculated
magnetic surfaces of the regime of magnetic
configuration in the place of carrying out of the magnetic
surface measurements: 1 - two half poles of helical
winding; 2 - toroidal carrying skeleton, on which the
helical winding is put; 3 - the toroidal vacuum chamber;
4 – the scanning rod coated luminophore; 5 - two LEDs,
which define the scale of the measurements
The LEDs were installed in the centre of ports on the
minor radius of the vacuum chamber in the cross-section
of the measurements on internal half of torus. The
luminescence of the rod under bunch of electrons
visualized the magnetic surfaces and traced separate turns
of the bunch. Each magnetic surface was recorded with a
CCD camera on one image, unlike the same thing by
means of Polaroid. The image with good scene of the
magnetic surface was got every time, when rod scanned
the cross-section of the vacuum chamber from top to
bottom. Scanning time for cross-section measurement was
within 92…120 s. It depended on positions of the
magnetic axis along R for a chosen regime of magnetic
configuration measurement. The capture images of the
magnetic surfaces were registered under changing the
178
radial positions of the e-gun, in 10-24 points along minor
radius. The superimposing the magnetic surface images
recorded at the different minor radii on one drawing has
allowed to get the structure of the nested magnetic
surfaces.

THE PROGRAM CONTROLLING
MOVEMENT OF A ROD
The composition of a hardware part of the complex
(Fig. 4) was selected, coming from requirements of the
task. Controlling movement of the rod was realized by
means of computer, equipped by L -783 module of the
company L-CARD. The module L-783 is intended for
building multichannel measuring systems, collecting
analog data, as well as digital control and checking the
condition of external devices. Conceptually L-783 is
faster PCI Bus Master Module, which has got the new
functional possibilities. The base functions of L-783 are:
multichannel analog-to-digital converter (ADC) with
multiplexing channels; digital asynchronous entering-
output and synchronous entering. Multichannel 14 bit
ADC of module L-783 allows the work with 16
differential or 32 channels with the general ground
connection. Each of analog channels is connected to ADC
through software operated attenuator, allowing assign one
of eight the measurement ranges of the voltage. The
Module L-783 provides the unceasing collection of
analog data given on sampling rate ADC from 0.005 Hz
to 2857 kHz. Presence of the special input of
synchronizing allows to hardware synchronization
moments of the starting ADC with the help of hardware.
Digital entering-output is presented as 16 input and
16 output digital (transistor-transistor logic) TTL -
compatible lines. The digital findings, as to user’s will,
can be transmitted to the third condition. Dual-link 12 bit
digital-to-analog converter (DAC) allows supplying with
the constant voltage of two independent channels.
So the program, controlling motion of a rod, works,
both with digital, and analog channels. The digital channels
were used for switching the direction of the rod movement
(upwards, downwards, inward and outward). But analog
channels measured the voltage while moving rod.
The program, controlling motion of a rod written on base
of the system of object-oriented programming C++ Builder 6,
works in Windows XP and executes 2 main functions:
1) calibrating, under which the factors are defined,
used for controlling movement of the rod by UAM-74 and
RM-09 micro motors (Fig. 5);
2) scanning the poloidal cross-section of the toroidal
vacuum chamber of the U-2M torsatron is produced on
chosen paths (one of three), to provide processing of
greatly available area of the cross-section of the chamber.

The given program uses the subroutines, falling into
staff software, delivered in the kit with a board L-783 of
the company L-CARD. These subroutines realize
controlling multichannel ADC with multiplexing channels
and transmitting the data to digital of the board L-783.
CONCLUSIONS
The presented measuring complex has allowed much
to relieve the experiment in the mode of real time, to
conduct it in the mode of remote access, as well as raise
reliability and validity of the results of measuring the
magnetic surfaces.
As result, one can see in Fig.6 an example of the
measurement of the closed magnetic surface, which has
average minor radius 0.2 m (the regime of the magnetic
configuration in U-2M has the operation parameter
Kϕ=0.31 [1]; the shift of the magnetic axis inward from
the circular minor axis of the torus is 5.7 cm).
