Explanation of Sketch 2
1. Old House
This building is to be converted to an administration building.
2a. Physical Science and Administration Building (40 - 50 x 15 meters, one-story)
The physical science building is composed of a basement containing a storeroom,
parking areas, machine room, and a battery-filling area equipped with one
LINDE apparatus for making liquid air (at temperatures as low as -160 degrees
centigrade). A large hall is to house the cyclotron, but it is still empty.
A smaller hall contains the neutron generator with a 200-kilovolt linear
accelerator with a deuterium beam on heavy ice (D 2 0). Neutrons of about

2.3 million electron volts are generated by the nuclear reactions. The
basement also includes a laboratory for Geiger counters with vacuum facilities
and oscillographs, a constant-temperature room, and two rooms for radium and
beryllium used in fast neutron physics; in these rooms there are square
depressions covered with heavy lead plates.
The first floor includes a TRACHT laboratory (biochemical) and a
laboratory for physiological research, consisting of six rooms where special
experiments on rats are carried on to investigate protection from radioactivity.
It also includes two lecture halls for 200-300 persons each, built in the form
of amphitheaters.
The second floor contains a large library which is stocked on a
continuing basis with specialized foreign periodicals and literature.
the nuclear physics library fgfi~iLy complete, based on present
scientific standards. Also on the second floor is a laboratory for general
physical sciences, equipped with oscillographs, measuring instruments of all
kinds, and tools, where PhysicistATOMAC works on metal evaporation; a small
electron laboratory where Engineer PRAELEC experiments; and the laboratory

(No information is available
on the size of the chamber.) In another part of this floor is the institute's
administration. An underground tunnel connects Building 2a to Building 9.
2b. Laboratories
The basement contains only storerooms for spare parts, equipment of
all kinds, and tools.

The refrigerator(for developing nnelear-phdtographic-p? .tes is also in this
laboratory. There is also a dark room in an isolated area; a room with an
electron miscroscope and a `',eiss
microscope with cold cathode; a laboratory for measuring electrical
capacitance with dipoles; five rooms for low-voltage current installations;
and an X-ray laboratory for determining the structure of crystals.
On the second floor, there is a spectroscopy laboratory, a laboratory
for microphotometry, a vacuum laboratory, several rooms for theoretical
t bta,d~ n
physics, a laboratory where the wife of Professor^PAJIC works on radiation
protection, and a spectroscopy laboratory for RA14AN effects.
Small workshop, 40 x 12 [meters], equipped with rotary lathes, small
drills, work benches, and carpentry [facilities].

t3. Cyclotron
A dugout has been built in the terrain which slopes southward and a
building constructed in the dugout, so that the cyclotron is protected on
three sides by the hill. The building is still under construction and is
to go into operation the beginning of 1957. The cyclotron will generate
12 million electron volts. Also, in this building, a hot laboratory is
to be built for the chemical processing of isotopes. A laboratory for
t-11- a
the mathematics group under Doctor Engineer 4BO$ANAC is also in this building.

9. Building still under construction, 40 x 15 meters, where the physical
K.
chemistry group under DoctorAILAIVIC will work on experiments in uranituu
production and allied processes, among other things.
10. Building still under construction, I1O x 15 meters, where the biology
department is to be housed.
The buildings will be supplied with power from the city net,Tor_r by
means of cross-country power lines. They will also have their own direct-
current power installation.
The entire area is enclosed with a fence and may be entered only with
institute identification, which must be shown at the entrance to UD U
officials. However, security is not taken too seriously, and eiiry)loyees
of the institute can receive visits from their families. Securit-r
responsibilities exercised b -r UDIa officials are restricted chiefly to
chcckin, identification papers at the entrance.
