time holds thehair for Theoretical Physics at the Berlin Eti-
versity. Moegli'ch is a Communist sympathizer; it is not known,
however, whether he is a~ member of the SED. His deputy in the
Institute is Dr. Hellmut Simon.
3. The Institute is divided into the following Departments:
a. Department for Structural Research (Strukturforschun
Dr. Hellmut Simon. The following are Simon's scient
1 Dipl. Phys. Gerhard Eichhoff
2 . Dipl. Phys. Hans Thiel
3 Dipl. Phys. Eduard Schnuerer
4 Diplomant Kessler (fnu)
5 Diplomant Walter Schweinberger
In addition, the following permanent personnel'belong to this department:
precision mechanic, Maassen (fnu); laboratory worker, Miss Kippoldt (fnu);
laboratory worker, Schepstadt (fnu); laboratory worker, Mrs. Ewerenz (fnu).
As of late August 1954, the scientific staff had in the recent past been
aged as follows:
M Simon: X-ray dosimetry with cadmium sulfide cells as indicators and
the study of the qualities of CdS crystals under X-ray radiation.
(b) Eichhoff was building a spectrograph for ultra-soft X-rays; it was
almost completed.

(c) Thiel had been engaged in the measuring of X-ray fields with CdS
dosimeters. At that time, he was building an installation for the
study of infrared elimination (Infrarottilgung) with CdS crystals
subjected to X-ray radiation.
(d) Schnuerer: X-ray absorption measurements with CdS crystals. He
was also engaged in the construction of an X-ray monochromator.
(e) Kessler had built a small Van de Graff installation of a few
hundred kV.
(f) Schweinberger was engaged in structural research on CdS crystals,
b. The Electronic Department, headed by Dr. Friedrich Eckart. He is assisted
by the following scientific personnel:
(1) Dipl. Phys. Gerhard Schubert
(2) Dipl. Phys. Heinz Dietrich
(3) Dipl. Phys. Gerhard Mueller
In addition, the department has the following technical personnel:
laboratory worker, Miss von Halden (fnu); circuit mechanic, Albrecht (fnu);
precision mechanic, Buettner (fnu). As of late.August 1954, the scientific
staff of the Department had, in the tecent past, been engaged as follows:
(a) Eckart: Measurement of the conductivity of purest selenium. and measure-
ment of its Hall effect. In addition to his work in the Institute, Eckart
also works with the Radio and Television Center in Berlin-A.dlershof.
(b) Schubert: Study of CdS subjected to bombardment with electrons of slow
and medium speed.
(c) Dietrich: Preparation of purest selenium. Construction of an install-
ation for growing monocrystals. Researdh on germanium and silicon diodes
and transistors. Dietrich has cooperated with VEB Werk fuer Nachrichten?
elemente "Carl von Ossietzky" (Dralowid) in Teltow for the development of
transistors.
(d) Mueller: Study of phosphorus subjected to impulse radiation with electrons*
c. Electro-Optical Department, headed by Dr. Wilhelm Muscheid until 30 June 1954,
now temporarily headed by Dr. Wilhelm Buttler. The following are its scienti-
fic personnel:
(1) Miss Dr. Ingrid Poppe
(2) Dipl. Phys. Brauer (fnu)
(3) Dipl. Chem. Udo Holland-Nell
In addition, the Department has the following technical personnel : laboratory
worker and mechanic, Bernau (fnu); laboratory worker, Ludeck (fnu); laboratory
worker, Richard Peschke; laboratory worker, Mrs. Zocher (fnu); laboratory
worker, Mrs. P llich (fnu); laboratory worker Pfeiffer (fnu). The Photographic
Laboratory of the Institute, headed by Mrs. Rieske (fnu), who is assisted
by Mrs. Gauger (fnu), is attached to this department. The scientific staff
of the department had been engaged as follows:

1954 . The department, as of late August 1954, did not have a head. It
was planned to call Dr. Pretz (fnu), an industrial chemist, as its head.
The personnel of the department are:
(1) Dr. Schlueter (fnu)
(2) Dr. Ebert (fnu)
In addition, there are the following: laboratory worker, Mueller (fnu);
laboratory worker, Matzkeit (fnu); laboratory worker, Sauvageout (fnu).
The personnel c-f the department were engaged as follows:
a. Department for Structural Research: The spectrograph for ultrasoft X-rays,
built by Eichhoff; a double monochromator; an E-ray structure installation
from the Seifert firm in Hamburg;2 several oscillographs, multiflex galvan-
ometers, etc.
b. Electronic Department: several oscillographs; an impulse generator; an
installation for the production of monocrystals; an ink r the
purification of germanium and silicon; a double mono chaatr , at.
