September 18th,1929.
Dr. Herman Schlundt,
University of Missouri,
Columbia, Mo.
Dear Dr. Schlundt:
Upon my return I found a letter from Dr. Hess,
acknowledging receipt of reprints which I sent him.
In his letter he states that for his study of
the ultra gamma or cosmic radiation he has developed a more sensitive
type of gamma ray electrometer, similar in construction to that which
we are using. He calls it the Kolhorster-Strahlingsappamat.
The
ionization chamber of this instrument has a volume of 4 liters, is air
tight and the fibers are mounted in the form of a double loop - the
electric capacity is only about 0.4 centimeters.
The instrument is manufactured by Gunther & Tegetmeyer
and costs about $150.00, F.O.B. Germany.
I am passing the above imformation along as I know
you will be interested.
Sincerely yours,
Vice President.
