Physics students
build muon finder
Particle telescopes to detect
high-energy muons that pene
trate hundreds of feet into the
earth’s crust are being built by
A&M physics seniors as a lab
project.
Their telescopes are “little
brothers” of 9V£ and 17-ton spec
trometer telescopes constructed
and operated at the university’s
Research Annex under U. S. Air
Force Office of Scientific Re
search support.
Heart of the Physics 425 “sen
ior lab” device is a student-built
Geiger counter containing a gas
mixture that is ionized by the
passage of a muon.
Three of the Geiger counters—
student made at about 70 cents
each (commercially purchasable
starting at $85)—are used in
connection with standard physics
lab equipment to detect the par
ticles.
Muons are “born” high in the
earth’s atmosphere when incom
ing cosmic rays collide with air
molecules. Pions and other class
es of particles also originate
through the process.
A&M students use burnt out
fluorescent light tubes and other
easily - accessible materials in
constructing the particle tele
scopes in the physics lab in
structed by Dr. Philip J. Green

and Dr. Nelson M. Duller.
“Lots of things can be done
with this equipment,” Duller
said. “Density flux of particles,
absorbtion characteristics, statis
tics of random events and time
resolution determinations can be
made.”
Dubbed “rocking chair” spec
trometer telescopes, the large
versions of the machines at the
Research Annex show the pass
age of the muon as a tiny light
ning trail in three 36 by 36 by
eight-inch spark chambers con
taining a helium-isobutane gas
mixture. Heavy magnets cause
the muon path to be bent, the
amount leading through calcula
tion to muon energy in electron
volts.
The annex spectrometer tele
scopes can be oriented at differ
ent angles with respect to the
horizon, for flux variation deter
minations.
Duller pointed out that the
student models set up in labs in
the physics building, discern and
count muons by automatically re
cording pulses from the Geiger
tubes on scalers. Also used in the
setup are amplifiers, power sup
ply, oscilloscope and logic cir
cuits.
Each of the three stacked one
and a half by eight-inch tubes
must be penetrated by a muon
for it to be recorded. The phys
ics professor said the particles
pass at the average rate of about
two per second through an area
the size of a person’s head.
The particles pass unaffected
through the atmosphere and
building construction to reach
the detecting machines.
All 19 students in the lab are
making counters and the ones
that “are working at all are
working well,” Duller said.
“It amounts to looking at a
microscopic thing with a macro
scopic gadget,” he added. “We
know the device is sensitive to
the muon particle because the
counter assembly as a unit does
not respond when a gamma radi
ation source is introduced,” he
added.
Seniors Coy Morris of Waco
and Milton Lumpkin of San An
tonio consider the project highly
appropriate and interesting.
“In other labs, textbook ex
periments are conducted for
known results,” Lumpkin said.
“We have more freedom in this
lab course.”

Distinguished status
awarded air cadets
Distinguished Air Force Cadet
status has been accorded 22 Tex
as A&M seniors, Col. Keith C.
Hanna announced today.
The professor of aerospace
studies noted DAFC indicates the
cadet has exhibited qualities de
sired by the Air Force in its ca
reer officers.
By making the distinguished
cadet list, the senior may be
designated a Distinguished Mili
tary Graduate and be commis
sioned in the Regular Air Force
upon graduation. With the DAFC
and a reserve commission, he
may apply for a regular commis
sion after entering active duty.
The 22 cadets were selected on
the “whole man” basis from
among 129 Air Force ROTC cadet
seniors. Military subjects pro
ficiency, leadership qualities, dis
ciplinary records, scholastic
standing and extracurricular par
ticipation are considered.
Twenty per cent of the gradu
ating class was selected under
the quota system. Three cadets
to graduate in December were
designated DAFC last spring.
Wearing the blue and silver
ribbon of DFAC on their uniform
are Thomas C. Bain Jr., deputy
corps commander, and John C.
Souders, Squadron 13 commander
of Dallas; John M. Braun, squad
ron 13 cadet, Austin.

Very simple. Be a

who is, in effect, his own
chairman of the board, He
has his own loyal clients.
He makes his own decisions
concerning them. And since
he is successful, who’s
going to argue?
Insurance counselling
is a field in which income
has no ceiling. It offers the
opportunity to perform
a highly useful service—
to corporations as well as
individuals. And consider
this: 22% of this company's
top agents began learning
and earning while still
in college.
