Investigation of Cosmic Rays on Atlantic Voyage
An expedition for the study
of cosmic rays
in the Atlantic area
departed from Riga on the "Kislovodsk"
on
26 November 1967.
The expedition
was organized by
the Siberian Institute of Terrestrial Magnetism,
long-
sphere and Radio Wave Propagation .
The vessel returned
to Leningrad on^
10 March
1966.
About 40
tons
of special cargo had
to be carried,
includ-
ing 10
tons
of balloons with hydrogen under
a pressure of
150 atm.
Cosmic
ray observations were made with
a three-section neutron monitor,- a stabil-
ized system of
35 meson and electron-photon telescopes and with strato-
spheric balloons.
About 40,000 individual measurements were made on
shipboard and
64 balloons were launched
for measuring cosmic rays
an
stratospheric temperature.
The charged component was registered w
_
crossed azimuthal telescope which made it possible
to use 35 channels
for
registry of
the soft and hard components
from different directions
_
angles
0,
45,
55,
65,
70 and
76°
to the vertical.
Six additional channels
were used
for checking telescope operation and determining random coinci-
dences.
A neutron monitor was used
for studying
the planetary distribution
of cosmic ray intensity.
It was
an
I GY monitor with Simpson:
listing of
three sections, each with
four SNM-8
counters.
The statistical
error for the monitor was about +0.7 percent during
2 hours
of registry.
It was calibrated using a radium-beryllium neutron source.
Sixty- four of
74 balloon launchings were successful
(complete data for each laun
g
are given in a table).
The collected information will make
it possible
to find
the barometric coefficients
for different cosmic ray components
and estimate their dependence on the energy of primary particles in the
range
1—20" 10^
eV.

(four telescopes of cubic geometry), a 42-
ehannel automatic recording system and an auxiliary recording device.
The
mean value of the supermonitor (operative sinee 19°7)
intensity is 506,000
pulses/hours; for the aximuthal telescope it is 246,000 pulses/hour.

instrument error for the supermonitor is £ 0.35$; for the azimuthal telescope
it is

Modification of Dipoles for Rocket Measurements
This article shows wind profiles to altitudes of 32 km obtained on
22 April 1968 using N5, CJ-5/l and CJ-5/2 dipoles.
The author describes
the merits of a new type of dipole
(CJ-5/2)
in comparison with type N5 used
earlier.
The new type
is a standard wind sensor for Polish meteorological
rockets.
A method for designing dipoles for wind measurements
is described
on the basis of the new type
(CJ-5/2) of dipole.
