film anisotropies. A study is made of the feasibility of optimizing the magnetic
properties by the selection of films according to thicknests and composition. It
is faund that, by selecting a thickness at which Hc is at a maximum, it is possible
to raise the current threshold of information decay. An increase in Hk with a
constant magnetostriction nt the films leads to a reduction of its angular di#.persion.
in view of which the alternating magnetization of the films in mutuall'y perpendicu-
lar fields corresponds closer to a simple model of magnetization rotation. An in-
crease in 1-1 leads to n proportional increase in the address currentti, but this may
be somewha
A compensated by decreasing the dimensions of the elements. The re-
lations obtained pertain to films the manufacture technology for which is still
being developed. Orig. art. has: 4 figures and I table.

ABSTRACT: The article deals with the problem of the processing of thin-film
matrices for the operational memory devices of computers and other related equip-
ment. A method is proposed whereby these matrices are checked for four thresh-
old characteristics (writing current "I", erasing current "I", writing current "0",
and erasing current "0"). These criteria are then employed to determine permissi-
ble current tolerances for the matrix and memory unit as a whole. The character-
istics are tested on a pulse stand under conditions simulating real conditions.
Various test techniques are considered. The pulse routine is shaped by means
of a generator. with the results of the test automatically recorded. The stand
itself. which is described in some detail, consists essentially of the generator
which provides the program required for the testing of the threshold character-

istics, a measuring unit, a broad-band amplifier, cope, a_ i )rnatic recorder,
and a triggering generator. The pulse amplitu,le is .rmed through the use of
power transistors which are gated. Leading c(, - r.. , time is no rn. e than 50nsec.
This test stand has been used for work with ma,;zxtic matrices and 11 nory cell

T EXT: The nonlinear theory of travelling-wave tubes (TWT)
is well developed (Ref. 1 - A. Nordsiek, PIRE, 1953, 41, No. 5,
1196; Ref. 2 - Vaynslifeyn, L.A., Nonlinear theory LBV, Parts

but leads to complex intogral-differential equations which
cannot easily be solved. It appears, however, that comparatively
simple methods of analysis of the nonlinear effects are pos--ible.
In particular, if it is required to evaluate the energy trans-
ferred to the field by a charge, it is not necessary to solve
the equations of motion and the energy E(t) or E(x,y,z) can

be determined directly from the system of differential
equations. The average power transferred by the electron
beam to the high-frequency field can then be found by deter-
mining the mean of the solution over the whole ensemble of
particles. This approach is illustrated in the article. It is
assumed that an electron noving ~Iong the axis x interacts

with the electric field E . e .cos(wt - Px) of the wave
propagating along a slow-do~n structure, also along the axis x
The equation of motion of the electron is in the form:

where:
e = ~e~_> 0; 0 = W/V

where V~ represents the phase velocity. Now, the elactron
efficiency can be expressed by-

and (3) are much simpler timn the exact equations (Rof. 1.).
These equations were inte~;rrited nui-.1crically and tile results are

bunching of the electrons is illustrated in Fi!~. 3, where tile
electronic efficiency of the system is plottoo as a function of
the coordinate y . Tile fi~;uros illustrate two cnges: in tile
first case, tile electron velocity is si-wall, which corresponds to
b = -1 , while,in the second cnse, the electron velocity is
comparatively higa (b = 1.5). The numbers shoin oil Lhe --urves
