SPEEDING ELECTRONS
Big 'U' Synchrotron Expected
To Be Operating by Late Fall
________a_______________________


By BOB MARGOLIN
Final adjustment and success-
ful operation of the University's
synchrotron, a huge doughnut-
shaped device that enables the
study of electrons moving at an
extremely high rate of speed, can
be expected late this fall, Prof.1
Robert W. Pidd of the physics de-
partment said yesterday.
At present, Prof. Pidd, aided by
Prof. Richard .Crane and others
working on the project, are near-
ing their objective of safely guid-
ing a beam of electrons through
the magnetic orbit in which it is
trapped.
- *
WHEN THIS is accomplished
just once, the beam will then be
propelled around its orbit at the
rate of 100,000 times in 1/80th of a
second. At this rate of speed the
beam will build up electron volts
numbered in the milligs.
"Reactions never observed at
a low energy volts can then be ob-
tained," Prof. Pidd explained.
This means that meson parti-
cles, thought to be the type of
particle that holds the nucleus
of the atom together, will be
* available for study. Meson par-
ticles are created at 2000,000
electron volts.
Two technical problems are now
being ironed out. One is to suc-
cessfully shoot the beam around
its orbit without striking a foreign
object, that is the walls of the
synchrotron or the injector used
to propel the electrons. The other
problem is that of shrinking the
orbit of the electronic beam so

that it will be impossible for the
beam ever to strike the injector.

CONSTRUCTION of the syn-
chrotron, a 20 foot high and nine
foot wide mass of wires and metal
weighing 15 tons located in the
subcellar of the Physics Building,
was begun in 1946 under the aus-
pices of the Navy.
Daily to Carry
Nuechterlein' s
News Views
Today's edition of The Daily will
mark the return of It Seems To
Me, a column on international af-
fairs written by Don Nuechter-
lein, '48.
Nuechterlein served in the oc-
cupation forces in Germany in
1945 and 1946, and when released
from active duty there in 1946
worked as a staff writer on the
Weekly Information Bulletin of
the American Military Govern-
ment in Berlin for a year.
Nuechterlein returned to the
University this fall after a sum-
mer of study at Oxford, and is
currently enrolled as a doctoral
candidate in the political science
department.
As a unusually well-qualified
commentator on Europe today,
Nuechterlein's column will run
every Sunday. His first explains
"Why Europeans Are Skeptical of
American Foreign Policy."
