Title Determining the time of transverse relaxation during magnetic
resonance of atomic nuclei in weak high-frequency magnetic field
Periodical Zhur. eksp. i teor. fiz., 29, August 1955, 227-230"
Abstract The authors develop a procedure for measuring -the time of trans-
verse relaxation which is based on a determination of the time
interval between extrema of dispersion signal in a weak high-
frequency magnetic field in the case of non-adiabatic transition
through resonance. They obtain relations and construct graphs
which permit one to determine the time of transverse relaxation.
For an experimental verification of the procedure they measure the
dependence of time of transverse relaxation uron the concentration
of paramagnetic ions in aqueous solutions of copper sulfate and
iron nitrate. Seven references: e.g. S. D. Gvozdover and V-1. A.

field
Periodical : Zhur. Eksp. i Teor. Fiz., 29, No 5, 637-644, 1955
Abstract : Two methods of longitudinal relaxation time determination are
devised, by using the envelop of dispersion signals observed in
a strong high frequency magnetic field during the variation of a
constant magnetic field, and by measuring the distance in time to
the inversion point. Correlations allowing the determination of
longitudinal relaxation time are derived. As experimental tests
of the method, measurements are carried out of the relation of the
longitudinal relaxation time to the concentration of paramagnetic
ions in aqueous solutions of copper sulfate and of iron nitrate.

PERIODICAL: Izvestiya vysshikh uchebnykh zavedenly, Radlofizika,
1959, Vol 2, Nr 2, pp 229 - 243 (USSR)
ABSTRACT: A problem similar to that presented in this article has
been dealt ifith earlier by S. Olving (Ref 2). A more
general approach to the- problem is attempted here, it being
assumed that the geometrical parameters of the tubes are
arbitrary. The notation adopted is similar to that of
earlier work (Ref 1). Also, a new function, defined by
Eq (1), is introduced; this is plotted in Figure 1. The
basic 1-inear:Lsed equations of the system, derived under
the assumption that the alternating components are
appreciably smaller than the direct ones, are similar to
those of Ref 1-
M(i~ffl, a-U0 = N(aT, b-r) (2)
where M, N and T are defined by Eqs (3), (4) and (5).

Characteristic Equation of the Travelling-wave Tubes for Medium
Currents
The right-hand side term of Eq (2) can be represented
in the form of Eqs (11). Tkt6secan be expanded into the
Taylor series so that N can be approximately represented
by Eq (15). M of Eq (2) can be represented by Eqs C17).
This can also be expanded into the Taylor series as is
shown in Eq (19). The final expression for M is given
by Eq (24). By substituting Eqs (15) and (24) into
Eq (2), an approximate algebraic equation, w1th X as
the unknown, is obtained. The resulting expression is
in the form of Eq (24) or, finally:
2
X(l + QBX)(X + L) = _ (1 _ QX)2 (26a)
where B is defined by Eq (26B). If the tube is such
that it fulfils the conditions defined by Eqs (28), the
characteristic equation is simplified and can be written
as Eq (29a). The function M can also be expanded by
moans of the asymptotic formulae provided the conditions
Card2/4 of Eq (30) are fulfilled; in this case, the characteristic

0506
sov/14l-2 2-11/29
Characteristic Equation of the Travelling-wave Tubes for Medium
Currents
equation is given by Eq (296 which coincides with Eo (29a).
Similarly, it is possible to expand the. function N by
jusaxis of the asymptotic formulae and the characteristic
equation is then in the form of Eq (30B). First, Eq (29a)
is investigated for L = 0 , which represents the condition
of complete synchronism. The equation is now written as
Eq (36a), which is a standard cubic equation; the complex
roots of the equation are plotted in Figure 2 (solid curves).
In the case of narrow beams, the conditions of Eq (28a)
are not fulfilled and it is necessary to solve the complete
fourth-degree characteristic equation (see Eq 26a). The
equation was solved for L = 0 for various values of B
Graphs �11ustrating the dependence of the roots of Eq (26a)
on Q for B = 0.25 and B = - 0.0635 are shourn in Figure 7.
It is eeen that the equation always has a pair of complex
conjngate roots having a positive real component. At small
Q and B> 0 the equation has a pair of negative real
roots which, for Q = Q*, coincide and become a pair of
Card3/h

complex conjugate roots. The paper contains an appendix
which gives expressions for the roots of Eq (36a) (see
Eqs 1-6A) and an asymptotic expression for the gain factor
of the tube (see the Eq 6"A). From' the analysis, it is
concluded that the complete fourth-degree equation has
complex roots (in the region which is of most practical
interest) which do not differ appreciably from thoseof
Eq (29a). The coefficient of depression derived on the
basis of Eq (26a) is twice lower than that of the "small-
current theory".

investigated by L.I.Mandellahtam and his associates (Ref.1) in
systems with lumped constants may also occur in wave systems
(Ref.2). The considerable interest in wave systems with
modulated parameters Is due to the prospects of building stable
amplifiers and frequency converters with a very wide band which are
simple to tune and are unidirectional. In principle, it is
possible to obtain in the wave systems noise characteristics which
are the same as those obtained in parametric circuit amplifiers.
One of the possible variants of wave systems with modulated
parameters are wave systems with long electron streams. First, a
freely drifting beam of electrons represents a form of transmission
line; modulation of the current density by a strong pump signal is

analogous to some extent to the modulation of the distributed
parameters of a transmission line (Ref.3 and 4). Another
example of a waveguide system in which the modulation of the
density of the electron beam can lead to parametric effects is a
system consisting of a beam of electrons linked with a delay
system. Wave systems with long electron beams are at present one
of the most suitable fields for studying parametric phenomena in
wave systems, since it is difficult to produce purely
distributed wave systems with semiconductors and ferrites. In
this paper the results are briefly described of experiments on
parametric amplification and transformation of the frequency in
wave systems with long electron beams in which the interaction
of the electrons with the high frequency field in the I
longitudinal direction is utilized (see also earlier work of
the authors, Ref-5 and 6). The experiments were made in the
centimetre (fc = 3000 -3500 Mc/s, frequency of fH-*g 6ooo mc/s)
and the decimetre (fc-- 1000-1800 Mc/s, fH = 3000 - 3500 Mcls)
ranges. In the experimental set-up both the pump source and the
signal were introduced into the electron beam by means of sections
of helical lines. The main beam of the electrons first passed

through the first helix in which it was modulated by the pump
signal and then into the second part of the tube where it
interacted with the signal. The interaction was realized either
in a drift tube (for feeding In and for extracting the signal,
small sections of helical lines were used) or in the helical line.
The power of the pump signal at the input and the output of the
first helix was monitored; measures were provided for filtering
the pump signal on the indicating apparatus. The block
schematic is given. The parametric amplification was clearly
observed in systems of both types for powers of the pump source
varying between 200 )LW and 1W. A common feature was the very
wide band of the parametric amplification. Thus, in the
decimetre range, the amplification was in a band of about 500 to
600 Mc/s with very little change in the gain for the band of the
pump source of 200 to 300 Mc/s. In conclusion, the following Is
stated. Parametric amplification in wave systems with electron
beams extends over a very wide band; for pump signal powers of
10 to 100 mW in systems with lengths not exceeding the dimensions
of ordinary TWT, a real gain of about 20 db and more can be
achieved. Comparison of the experimental data with results of

calculations by W.Loisell and C.Quate (Ref.3 and 8) shows that the
theory does not adequately explain the observed phenomenon.
Firstly, disregarding of the combination frequencies is not
justified and, secondly, various phenomena, as for instance the
non-monotonic relationship between the coefficient of parametric
amplification and the power of the pump source etc, are not
explained by the work of Loisell. On the other hand, a number of
experimental facts are in qualitative agreement with the theory;
for instance, the selective properties of the investigated systems,
the dependence of the coefficient of parametric amplification on
the voltage of the beam for systems with a beam and a delay line.
In the investigations described, no special measures were taken
for picking up the noise energy; the minimum noise coefficient
of the systems investigated was at the level of the noiae of the
appropriate travelling wave tubes. Even in their present state
electron wave parametric systems may be of interest from the point
of view of wide band mixing and division of frequencies.

was built in such a way that the sig
propagated along two symmetrical strip lines having the stuno
external plates. The amplifier consisted of 10 sections in which
the diodes had a-capacitance of 0.27 0-3 PF, the equivalent
inductanue was 1.5 x 10-9 H and R S 5 - 7ohm. With optimum
value biasing voltages of the diodes, an operating bandwidth of
12%) was obtained and the maximum gain was 13 tit). The calculatcd
value of 'gain by using Eq., (2a) was 12 db. The aiiiplifior idith
series-connected diodes also consisted of two syimiietrical strip
lines and the decoupling between the signal and pump lines was
about 12 db. A bandwidth of about 104% and gain of 7 db were
obtained with this -amplifier. The noise factor was about 11 to5
db. The formulas for calculating the gain are reasonably accurate,-
in particular, for amplifiezisoperating over the frequency range
in the vicinity of the' resonance frequency of the diodes. However,
the experiments and theory scem to diverge at em waves, which can
be explained by the presendeof additional losses caused by the.
contact of the diodes with the conductors of the line.
