Some specific design features of the accelerating units for LINACs model UELR-10-10S designed for radiation
sterilization and the electron beam characteristics obtained experimentally are considered.
PACS: 29.17.+w
The linear electron accelerator model UELR-10-10S
is intended for the commercial radiation sterilization
and pasteurization of foodstuffs. The radiation parame-
ters of this machine are shown in Table 1.

The KUY-147А klystrons produced by FSUE
“Toriy” are used as a source of RF energy. At the con-
sumer’s request, it is possible to use other types of
klystrons produced by foreign firms and generating a
pulse power of 6 MW at a frequency of 2856 MHz with
an average beam power up to 30 kW.
The standing wave accelerating structure contains a
five-stage buncher, which ensures narrow energy spec-
trum and RF focusing of the beam of accelerated elec-
trons. The main operating mode is the mode without an
external solenoidal focusing magnetic field, which en-
sures the production of the beam of accelerated elec-
trons with an energy of 10 MeV and small energy
spread.
In the first machine of this model, a double-electrode
gun IED-50-0.4 with BaNi cathode of 5 mm diameter
was used. In the second such a machine, we applied a
gun with a cathode of 14 mm diameter.
The main experiments were carried out to measure
the kinetic energy of accelerated electrons, the range of
energy variation, energy spectrum and current of accel-
erated electrons. The energy of accelerated electrons
was mainly varied by varying the beam current, which
ensured high electron efficiency.
A so-called injector device, a beam current regula-
tor, was the main means used to vary current magnitude.
It is positioned between the electron source and acceler-
ating structure and consists of a focusing lens, a drift
tube and a collimator. By changing the lens current, we
changed the losses of the beam passing through collima-
tor, the current injected and the beam losses in acceler-
ating structure.
In some cases when measuring load characteristics,
the beam current was changed by varying the filament
of electron gun. In standard version of the accelerator,
two Al plates located in the atmosphere beyond the vac-
uum window of the scanning magnet chamber were
used to control the kinetic energy of beam current. The
energy of accelerated electrons was estimated from the
absorption of the beam current in the first Al plate. To
measure energy spectrum in our studies, we used a mag-
netic energy analyzer. The effective energy of the beam
extracted to the atmosphere was measured in compli-
ance with the ASTME 1649-94 standard by using a set
of Al plates of 2 mm thickness. Film dosimeters of the
SPDF-5/50 model were placed between Al plates.
In the beginning of the experiments with the first ac-
celerating unit, some difficulties emerged in the use of
current regulator. The reason was parasitic magnetic
fields in the area of electron gun produced by an annular
magnet, a component of an ionization lamp used to con-
trol vacuum. These fields distorted the trajectories of the
electrons injected to accelerating structure. To correct
the position of the beam at the inlet to accelerating
structure, we were forced to use the magnetic fields pro-
duced by the solenoid coils encircling this accelerating
structure. To produce these fields, a current of 16 A was
applied to the coils of solenoid. By varying the current
in current regulator from 230 up to 300 mA, we man-
aged to control the current at accelerator outlet and to

obtain the load characteristics shown in Fig.1. These
characteristics were measured in different ranges of lens
current variation. At lower magnetization current, one
load characteristic was less steep, which evidently can
be explained by higher beam losses on the walls of ac-
celerating structure. At low current in the lens, the ac-
celerating structure was loaded with a current higher
than the current recorded by the beam absorber located
at the outlet of accelerator.
Fig.1. The load characteristic of the first accelerating
structure with current varying in current regulator.
Ibeam = 230-280 mA
The 10 МeV kinetic energy of electrons was attained
at a beam pulse current of 0.21 А. When a standard
pulse klystron modulator with a duty cycle of QRF = 240
was used, the duty cycle of the current of accelerated
electrons was QI = 270, taking into account the time
necessary for the onset of oscillations in the accelerating
structure.
The 210 mА pulse current corresponded to an aver-
age beam current of 0.78 mА, which in turn would cor-
respond to an average beam power of 7.8 кW and did
not ensure specified average beam power.
In the course of studies of the first accelerator car-
ried out without current regulator, it was experimentally
confirmed that an average power of 7.8 (8.2) kW was
obtained at a kinetic power of 10 MeV (see Fig.2). In
this case, to change beam current, we varied the fila-
ment current of electron gun. We succeeded in obtain-
ing high current of accelerated electrons by increasing
the current in the coils of solenoid up to 50 A (Fig.2).
Fig.2. Load characteristics of the first accelerating
structure without current varying in current regulator
The average kinetic energy of accelerated electrons
in both the cases considered above was estimated from
the absorption of current in Al plate of 10 mm thick-
ness. It should be noted that the total current values
shown in Figs.1 and 2 were determined as a sum of cur-
rents in these two plates. Due to leakage, these values
were less by 6% than the current measured by beam ab-
sorber. In this connection, the average beam power at-
tained at a kinetic energy of electrons of 10 MeV could
be considered equal to 8.2 kW instead of 7.8 kW, and
the pulse power generated by the klystron was estimated
to be 4.5…5 MW.
With the magnetic energy analyzer used, the spectral
energy characteristics in the first accelerating structure
were measured at a current of 58 А in the first focusing
coil and 35.5 A in the second and third coils. The depen-
dencies of the kinetic energy of accelerated electrons at
the maximum spectrum and maximum FWHM on the
frequency of RF oscillations were measured at the same
current (see Fig.3). The minimum width of energy spec-
trum obtained FWHM of spectral curve was 2.8% and the
kinetic energy at the maximum energy spectrum was
9.7 МeV at a beam pulse current of 253 mА.
Spectral characteristics were also measured without
focusing field. In this case, pulse current was reduced
by 13…17%, and the kinetic energy at the spectrum
maximum and optimal frequency of RF oscillations in-
creased up to 10 MeV, which evidently can be attributed
to a decrease in the current of accelerated electrons
(“unloading” of accelerating structure). Fig.4 shows the
beam energy and energy spread as a function of the fre-
quency of RF oscillations. It is important that without
solenoid coils, the energy spectrum width FWHM of
spectral curve was reduced to 2%.
It should be also noted that with RF focusing only,
we managed to attain a beam of accelerated electrons
with smaller diameter.
When testing the second accelerating unit, we used
the KUY-147А klystron with a pulse power of 6 MW,
approximately, (duty cycle was QRF = 240).
We used the methods of the ASTM 1649-94 stan-
dard to measure the effective energy of the beam; it was
10.9 MeV at a pulse current of accelerated electrons of
270 mA. With a standard duty cycle of the beam of
QRF = 270, this pulse current corresponds to an average
beam current of 1 mA, i.e. an average beam power of
10.9 kW is attained. At reduced kinetic energy, higher
beam power can be obtained, for example, by increasing
the beam current by feeding currents to the coils of fo-
cusing system without changing the filament of electron
source.
As was mentioned above, when testing the second
accelerating unit, we used the double-electrode gun with
the cathode of 14 mm diameter. In this case we obtained
lower density of the current removed from the cathode,
however, wider energy spectrum was observed (up to
10% HWFM spectral line), and higher beam losses oc-
curred when passing through accelerating structure.
Probably, the use of this electron gun with new optical
elements contributed to larger diameter of the beam on
extraction foil, which was placed 1300 mm from the
outlet of accelerating structure. Besides, to increase the
cross-section size of the beam, we used the current of
the lens of current regulator and the currents of focusing
coils (Table 2).
The beam diameter was measured with a film
dosimeter of the SPDF-5/50 model, and the method of
photometry was used.

The radiation field flatness over the scanning length
not worse than ±5% was obtained due to programmed
shape of the current in the coils of scanning magnets.

A 30-minute test of accelerating unit was performed
under rated operating conditions. In so doing, the
steady-state thermal mode of the equipment of acceler-
ating unit was attained. The instability of the energy and
current of the beam of accelerated electrons was less
than 2%, even without stabilization systems with feed-
back circuits. This test was performed for a short period
of time to limit the radiation impact on the ionizing radi-
ation-sensitive units, which were located in the area of
radiation danger because of the layout possibilities on
test stand.
When experimentally studying the accelerating units
of UELR-10-10S LINACs, we obtained convincing evi-
dences that the klystrons with a pulse power of 6 MW
and an average power of 25…30 kW allowed the ob-
taining of the beam performances necessary for effec-
tive application of these linear electron accelerators to
commercial systems for radiation processing.
