Expect Satellite to Bring
Cosmic Ray Information
(Continued from Page 1)
of high-energy secondary rays in-
creases with altitude. Sometimes
their character changes, too.
The salt mine studies were made
to investigate a report from Hun-
gary's coal mines that a strong
neutral secondary cosmic ray had
been found that gained relative
strength with depth.
Studies inhthe salt mines here
and at Cornell indicated this .was
wrong, that the particles were the
same kind as the most abundant
at sea level.
Prof. Hazen studies great air
showers of secondary particles that
reach the earth simultaneously.
They are produced by very high-
energy primary rays striking the
earth's atmosphere. He makes es-
timates *of the primaries' energy
from the size of the shower.
His studies are directed at an-
swering two main questions about
How Great Is the Energy?
First, how high does the energy
of primary rays go? How big can
an air shower get? Tfie greater
the energy, the straighter the path
they followin our galaxy. If the
energy is great enough, the rays
may escape the galaxy as starlight
does instead of remaining in a
circular path within stellar mag-
The second question concerns
the origin of cosmic rays and its
cosmological implications. Best
guess, according to Prof. Hazen,
for the origin of cosmic rays is
collisions of stellar clouds and ato-
Under this theory of the late
renowned atomic physicist Enrico
Fermi, collisions have been work-
ed out mathematically. After their
production, which is seen as a
sizeable power load on the gal-
axies or the universe, the rays be-
come trapped in their galaxies by
All these uncertainties about cos-
mic rays, which Prof. Hazen stu-
dies from high-energy secondaries
on the earth's surface to low-en-
ergy primaries in the upper at-
mosphere, should become at least,
partially cleared up if a satellite
is successfully launched.
