Linear Accelerators; (Cont.)
SOV/2003
linear electron accelerator. The method was suggested by 0. A. Val'dner.
It is shown that the use of this method for accelerators of over 3-5 Mev may
by three times the nonuniformity of energy of the output beam. The authors
discuss ways of applying this method practically and show that by using this
method the longitudinal stability of particles is not disturbed. There are
6 references: 3 Soviet and 3 English.
Tragov, A. G. Phase Shifter With Two Dielectric Plates 91
The author discusses a phase shifter in which phase shifting is accomp-
lished by moving two dielectric plates in the cross-section of a rectangu-
lar waveguide; It is shown that the use of two plates instead of one
makes it possible to increase the phase shift and decrease the size of the
phase shifter by one and a half times. Results of theoretical and ex-
perimental calculations are presented. There are 2 references, both Soviet.

TITLE: An electrical model of a linear accelerator
PERIODICAL: Pribory i tekhnika eksperimenta, 1961,4~io.4, pp.25-26
TEXT: In view of the increasing number of electron accelera-
tors which are either being built or are being designed, it is
desirable to evolve methods for the preliminary calculation of
the beam parameters. From this point of view the machines can
be divided into two groups, namely, those with a working energy
of less than 30 MeV and those above this energy. Design calcula-
tions carried out at MA ~ 0 (MIFI) showed that in order to
ensure the necessary beam parameters all the accelerators belonging
to the second group can be discussed in terms of the same solution
describing the electron dynamics during the acceleration process.
The situation is different in the case of the first group, i.e. in
the case of low energies. The electron dynamics in linear
accelerators of this type can be described by the following
equations:

where cp is the phase angle of the particle relative to the wave
and y, I - A, PH and 0.3 are the dimensionless energy, linear
coordinate, electric field amplitude, wave velocity and electron
velocity, respectively. This equation can only be solved by
numerical integration. It is, therefore, interesting to produce
an electrical model for this act of equations. A model is
particularly useful if the electron energy is to be adjustable.
The search for acceptable solutions can be reduced to the selection
of functions describing changes in the accelerating wave amplitude

TEXT. Two series of linear electroi accelerators have been developed and
are rea6 M for convercial production, one rated 3 H6V and the other 5 MeV. In
additi.,n, atperimental models of seven accelerators rated from 2 to 7 MeV have
:been built ard investigated. Along with the development work, theoretical studies
of particlc dynamics and of the high-frequency processes have been caried out at
the Institute (by S. P. Imnev, G. A. Tyagunov, A. G. Wegov, and A. V. Shallnov).
The caculations; have been ompared with experiment by Ye. G. Pyatnov. The staff
of the Microwave laboratory,,headed by N. P. Sobenin, plotted mere exact para-
metric -curves for the diaphragned wavepAde and made other investigation. A spe-
cial study of the matching of the generators with the accelemtor was made by
0. S. Milovanov. The assembly, adjustments and startup were under the leader-

TITLE-: Comparison of.experimental and theoretical characteristics of
waveguide buncher for 3 MeV
SOURCE: Moscow. Inzhenemo-fizicheskiy institut. Uskoriteli. no.3. 1962. 121-135
TEXT: A special test setup, U-1-M, constructed for a study of, the experiin-
ental characteristics of bunchers and to ascertain the agreement between the
theoretical and experimental data, is described and the main experimental res
ults obtained are presented. The setup comprises a 3 MeV linear accelerator
with housing of ad3ustable length to accomTodate bunchers of different sizes7
and with exciting coils so arrenged as to produce a magnetic field of variable
length. The relative phase velocity and field intensity were such as to pro-
duce a narraw phase bunch (60 at half-height of the phase spectrum and 250 at
the-base) containing 905 of the electrons, at a load current of 100 mA. The
waveguide was of the loaded type assembled of individual rings and diaphragms
on stainless steel dowels. The theoretical and experimental distributions of
the phase velocity along the buncher were in good agreement, but there was a

disparity between the theoretical and experimental attenuations along the
buncher The behavior of the frequency, power, and current characteristics
is analyzed and eyplained from the point of view of the phase stability prin-
ciple. The experimental characteristics were found to agree within 3-4% wit,~
the results of the theory developed at the Moscow Fngineering-Physics Insti-
tute at low'values of power. A similar agreement is found with respect to
the width and form of the energy spectrum$ indicating that the numerical
integration of the equations of motion of r, single electron (the "sirgle-
electrory theory, wi-th no account taken of the space charge of the acceler-
ated bunch, lateral motion of the electrons, etc.) is applicable at least
for pulsed currents up to 300 mA. It is pointed out that in the design of
special accelerators with narrow phase or energy spectra it is necessary to
analyze thoroughly beforehand the data governing the choice of the oparating
region of input parameters (frequency and high-frequency po;4er of the gene-
rator) such as to attain the required stability of the accelerated beam.

TEXT: It is sho-~-;n that the dependence of the group velocity in a linear el-
ectron -.accelerator on the geometric dhzensions and phase velocity of the wave
can be- represented for an iris waveguide in parametric form. Parametric curves
-are plotted for ir/2 modes- from the results of experimental data. The parameters
involved are k a (where k = WX is the wave number of the n-th niode with
wavelenpth X Rnd.2a is tRe diameter of the iris opening). k b (where 2b is the
inside diame
Per of the-waveguide proper), 8 (the phase vkoPity), and n (the
relative thickness of the diaphragm). The Rxperimental curves are plotted for
the following parameter ranges:S -,from OA to 1, X- frcin 10 to 11 an, a/b -
frcm 0-.2 to O.S. a/I - f~= 0.08 to 0.2, and iris thickness 0.4 an. 1he group
velocity is then readily obtainable from an approximate formula. The errors
of the method are-analyzed. There are two figures and two tables.

TEXT: An accelerator with continuous output energy variation is
required for some applications in physics and chemistry. For a
short accelerator such an energy variation is best obtained by va-
rying the frequency of the microwave power supply. To vary the
energy of a pulsed 200 mA electron beam with the range 1 - 2 MeV it
is necessary to: (1) select the accelerating system so that it
gives the required energy variation within a specified fre(~uency
range without too much broadening of the energy 8pectrum; (2) en-
sure satisfactory working of the microwave source within the spe-
cified frequency range. The present paper deals only with the first

point. It is shown that using a A = 10.5 cm 1.5 MW source of micro-
wave pulses an energy variation from 1.3 to 2.1 MeV may be obtained
by varying the source frequency by 10 Me/a; the width of the energy
spectrum under these conditions does not exceed 18%. There are 3

TITLE: Use of untunable magnetrons for power supplies of li-

SOURCE: Inzhenerno-fizicheskiy institut. Uskoriteli, no. 4,
1962, 7-11 , Moscow
TEXT: The use of untunable magnetrons in power supplies of linear
electron accelerators gives the advantages of lower cost, longer
service life and higher available power, compared with tunable
magnetrons. The present paper deals with problems caused by fre-
quency deviations from the nominal value in mass-produced untunable
magnetrons. A corrugated waveguide used in conjunction with a
magnetron should be designed so that the frequency deviation in
the latter does not greatly affect the energy and spectrum of the
accelerated electrons. Design calculations are given for the fol-
lowing accelerator model, called V-O-O(U-20): a circular waveguide
with a parameter a/k = 0.3, accel6rator length 2 m; here a is the

radius of apertures in the diaphragms of the corrugated waveguide
and A is the working wavelength. The calculations were carried out
on an analog computer and they showed that, under certain speci-
fied conditions, a satisfactory electron-energy peak is obtained
at 5 MeV. The authors consider also the frequency dependence of
the electron energy for an accelerator of y-,jd_(U-12) and show
that its large microwave power margin (only 25',"o of the power is
used for electron acceleration) can be used to increase the beam
current. There are 6 figures.

ABSTRACT: The performance of a linear electron accelerator recently developed
at the Moskovskiy inzhenem-fizicheskiy instit-ut (Moscov Engineering-Physics
Institute) is described. This unit has a diaphragmed accelerating wavegaide
consisting of a first (buncher) section 122 cm in length, containing 54 segments of
varying.cross section, and a second section 78 cm In length containing 30 segments
of cojastant cross section. Over the entire length the phase velocity rises from
0.436 to 1.00 and the voltage gradient from 17.4 to 26 ky/cm. The power source is
an 6-band magnetron of 1,5-megavatt peak power, Working at 400 cps with pulses of
2.5 microsec. This yields a beam of 70-microamp average current and a 4--5
Hev energy, with an energy spectrum of approximately 5~ and an average beam power
of 300 watts. With optimum decelerating target, a Gamma radiation level of
Card 1/2

600 r/min is attainable at a one-meter distance normal to the target. Accelerator
characteristic curves are given as measured over the magnetron frequency range of
.6.79--6.85 me. Tests show that accelerator efficiency, defined as the fraction of
h-f pulse energy transferred to the beam, can attain 25%. To arrive at this the
beam energy ~ms determined from its absorption in aluminum foil layers. The main
operation difficulties cited are in obtain' the optilm- match of the waveguide
to the magnetron and in getting axial nyumetry of the magnetic focussing field
in order to prevent beam losses in the guide. This model is an improvement over
an earlier version in its maximm beam energy and radiation produced, as well as
in construction and reliability. Several units are in current operation. Orig.

TEXT: The authors report on'the design and construction work carried
out at the j.,oskovskiy inzheherno-fizicheukiy institut (Moscov, Institute'
of Physical Engineering) wh ich led to the series production of -four
types of electron linear accelerators: Y-10 (U-10), y-12 (U-12), Y -13
(U-13) and '/ -16 (U-1'6). U-10: Total electron energy 3 Mev, mean current
200 pa (can be raised to 600 pa), 7-ray intensity 260 r/min; waveguide
length 122 am (54 cells). The phase velocity of the Pv- wave lies
between 0-436 and 0.987, the mean load parameter a/X - 0.16, th~
amplitude of the E-field is 17.4-30.0 kv/cm. U-12: electron energy
5 Mev, mean current 100 ga, -1-ray intensity 600 r/min; waveguide length
200 cm (84 cells), the last 78 cm (30 cells) are equal. PV - 1.00;

ABSTRACT., The stated purpose of the paper is to s=marize the results obtained at
Tartu (Institute of Physics and Astronomy of the Estonian SSR Academy of Sciences) in
studies aimed at elucidating the role of activator ions in formation of electron and
hole traps. The basic experimental data were obtained in investigating different
2+
alkali halide crystals activated by Gat, Int, T1+, Go , Pb2+, Cu+ and Ae ions. A
gonoral discussion ofl.the luminescence centers in such phosphors has been publishod
elsewhere (N.E.Lushchik and Ch.B.Lushchik, Tr. In-ta fiz. I astron. AN XstSSR, No. 6,
5, 1957). It is noted that the character of traps formed by activators is determined
primarily by the charge of the activator ion. For example, Bi3+ ions are readily re-

duced to Bi;~+ and trap an electron in the process and Pb
ions in a KC1 lattice act as effective electron traps. A ntmber of other cases of

effective electron trapping are mentioned with references to the papers describing
the corresponding investigations. Mention is made of decomposition of atomic centers
in ionic crystals, and a table gives the.values of the decomposition temperature for k
atomic Ag, TI and Cu.1n different alkali halides. The question is then raised
whether activator centers in-the same systems are also capable of trapping holes.
Recent electron paramagnetic resonance studies and optical experiments indicate that
silver at any rate is capable of forming hole traps in alkali halide crystals. Refer-
once is made to other studies and It Is concluded that as a rule (and not as an
exception) activator luminescence centers in Alkali halide crystals are capable of
trapping both electrons and holes, so that in many cases in alkali halide crystal
phosphors luminescence of activator centers is observed as a result of both reccmbina-
tion of electrons with trapped holes and as a result of recombination of holes with;
trapped electrons. Orig. art. has: 1 table.

TITLE: Low-temperature reduction of zirconium tetrachloride wih
alkali metals
PERIODICAL: Jaderni energie, Ano. 1, 1962, 21-22
TEXT: The article, based on dissertations submitted to the Technology
and Nuclear Physics department of the 6VUT (Czech Institute of Techno-
logy) in Prague describes a novel method of zirconiumtetrachloride re-
duction with alkali metals, namely sodium, at lower temperatures which
eliminates the disadvantages of the conventional Kroll process. Larger
scale ZrCl 4 reduction, at lower temperatures, is possible when the re-
active surface of the alkali metal is continuously renewedg and the re-
action temperature in dissipated during the reduction. These require-
ments are fulfilled by a reduction apparatus consisting of a calorime-
tric bomb and a pyrometric tube. The bomb, filled with steel,balls, is

Low-temperature reduction V291/D304
inserted into an electric stove and connected to an electromagnetic vi-
brator. The alkali-metal surfaceis continuously irritated by the vibrat-
ing balls which simultaneously serve to dissipate reaction heat. Tests
have shown that the reaction temperature depends on the alkali metal used
for reduction (appr. 490C for Na, 990C for Li, and 320C for K), and on va-
rious other reaction parameters, namely the dimension of the steel balls
and the vibration amplitude. The metallic zirconium is obtained in the
form of a powder or a compact mass. In conclusion, the author summarizes
the advantages of the new method as follows: (1) Energy is saved due to
the low reaction temperature; (2) pressure vessels of high-grade steel
can be avoided; (3) the product can be removed more easily from the re-
actor; (4) the reduction can be made with greater charges and requires
less time. There are I figure and 6 references, 4 Soviet-bloc and 2
non-Soviet-bloc. The references to the English-language publications
read as follows: B. Lustmann - F. Kerzo: The metallurgy of zirconium,
London (1955); G.H. Miller: Zirconium - London (1954). (Technical editor's
