1. INTRODUCTION
At present in the USA, Europe, Japan and Russia [1]
major attention is given to works on developing and
introducing the beam-plasma methods for modification
of surface properties of materials. The important
circumstance is also that in a series of cases the plasma-
beam treatment allows to obtain such structure-phase
states of materials which can not be realized by
traditional methods.
The modification of surface properties of materials
by means of powerful pulsed electron beams is one of
quickly developing and effective methods. When a
material is under action of such a beam, its layer (of an
order of particle path in this material) can be heated
very quickly to temperatures of phase transitions. The
heating and cooling rates depend on properties of a
material and beam parameters - the heating rate can
reach 108...1011 degrees/s and the cooling rate reaches
107...109 degrees/s. All this is realized in a so-called
adiabatic mode of irradiation when the energy carried
by the beam into the material remains within the limits of
a surface layer during all the period of beam duration, i.e.
it does not propagates deep into the material at the
expense of a thermal conduction. After the beam pulse
duration is finished there is a quick cooling of the treated
layer due to the heat conducting deep into the material.
2. EXPERIMENTAL PART
In the source under development one uses a
principle of obtaining an intense radiation of γ-quanta
under irradiation with a pulsed electron beam of
converters made from materials with a large atomic
number. For this purpose the accelerator “Start” is
involved [2], in the diode of which the electron beam is
formed with the following parameters: electron energy
Е=0.7...1.0 MeV, beam current I=10 kA, current pulse
duration (on half-width) t=10 ns. In these experiments
the geometry and the beam parameters were chosen so
that they should correspond to sizes of detectors and be
generate the maximum γ-radiation value. The scheme of
the experiment at the “START” is shown in Fig.1.
Measuring of beam current duration was performed
using the Rogovsky belt, and Y-radiation was measured
by means of the pin-detector.
The oscillograms of a current and γ - radiation are
given in fig.2.
Fig.1. Scheme of the experiment at the accelerator
“START”: 1-cathode, 2-anode, 3-magnetic field,
4-Rogovsky belt, 5-converter, 6-channel of X-ray
diagnostics, 7-insulator, 8-detector of γ - radiation
Fig.2. Oscillograms of the beam current (a)
and γ - radiation (b)
It should be noted that the current duration measured
by the Rogovsky belt (fig.2,a) coincides with the
radiation duration measured by the pin-detector
(fig.2,b). The electron beam density is given by a
system of beam formation and can be in limits 0.1...1.0
МА/cm2 [3].
The γ-radiation was generated due to the beam
deceleration at the converter made of refractory
materials (W, Ta) and installed on the anode of the
diode of the accelerator instead of the grid. The
maximum depth of 1 MeV electron penetration into
tungsten is according to [4]: δ = 10-5· E3/2 /ρ = 0.17 mm,
where: ρ is the specific weight of tungsten (g/cm3), Е is
the electron energy (keV). Consequently, as a converter,
one can use a tungsten foil with a thickness of 0.15...0.2
mm.
The γ-radiation and the absorbed dose were
measured with the use of a pin-diode and a LiF absorber
arranged at different distances from the converter. The
absorber was a polycrystalline LiF pellet (d=3.5 mm,
h=2 mm, S=10 mm2, ρ=1.17 g/cm3) activated by Ca,
Mg and Ti. The absolute values of the absorbed dose

were measured with the help of a tested universal
thermoluminescent dosimeter DTU-01. The best studied
is the mode of the tungsten plate (б=0.25 mm)
irradiation with an electron beam of a current density
equal to J=0.2 МА/cm2 (Ib=10 kА, rb ≈0.2 сm, Sb ≈13
mm2). The increase of the current density leads to the
burning of the converter that limits the intensity of the
γ-radiation bremsstrahlung flux. The burning of the
converter, as a rule, takes place at 5-6 pulses, and the
size of the burnt hole corresponds to the beam size (see
fig.3).
Fig.3
The maximum value of the absorbed dose measured
in the channel 6 (fig.1) at a distance 132 mm was ≈
102 Gr. The total dose can be increased by two orders of
magnitude by the repeated triggering of the accelerator.
Fig.4. Scheme of the experiment at the “TEMP-B”1-
cathode, 2-anode, 3-magnetic field, 4-converter, 5
-detector of γ - radiation, 6-collector, 7- Rogovsky belts
Similar measurements were carried out also on the
microsecond REB accelerator “TEMP-B” with the beam
parameters: Еb~1 MeV, Ib~25...45 kA, t~2.5 µs. The
scheme of the experiment at the “TEMP-B” is shown in
Fig.4. In these experiments the beam had the following
parameters: Еb~0.5...0.6 MeV, Ib ≈25...30 кА, and dura-
tion ~2.5 µs. The cross-section beam area was
~700 mm2.
The measuring of the γ-radiation and absorbed dose
was conducted similarly to the measuring at the
“START”. As a converter we used Ta (pos.4, fig.4)
placed directly on the collector (pos.6), and the LiF de-
tector was installed in the converter space behind the
converter. Time characteristics of the γ-radiation were
measured by the pin diode placed on the outside of the
flange in the collector region. The absorbed dose per
one pulse for a LiF pellet was ~400 Gr, and, conse-
quently, the total dose was ~3⋅104Gr. The increase of the
dose can occur due to the increase of the pulse quantity.
3. CONCLUSIONS
So, it was shown experimentally that on the base of
nanosecond and microsecond REB accelerators one can
develop the γ-radiation sources with 0.3<Еγ <1.0 MeV
and different cross-section areas 12<Sγ <700 mm2,
moreover, the absorbed dose can be varied from 102 Gr
to several units 105 Gr.
