Task-II - Item 1. "Submicron Measurement Error Analysis"
Search continued for data on damping and dimensional stability
of the materials under consideration. Extensive information
was found on quartz, a limited amount of information was found
on the metals, and almost no information was found on granite.
Two other materials have some interesting properties which may
be suitable to the application. Beryllium has a high modulus
of elasticity and low density. It is used for large optical
mirrors so must have good dimensional stability. Certain
ceramics made by reportedly
have zero therms coefficient o linear expansion.
From work to date, it appears that no one material is best
suited to all structural parts of a measuring engine. Three
separate applications are apparent:
a. The outer truss structure.
b. The bed which is the most massive block of material
in the instrument.
c. The measuring device itself and the film holding
platen.
STAT
The requirements of each will be separately considered.
Task II - Item 2. "Signal Strength of Broadcast Radiation
0 osed-Circuit TV"
The preliminary technical report prepared in November, 1964,
presented the data available and information on test facilities
required.
Work in December, 1964, was aimed at defining a pilot test
program. appeared to be the most

laboratories. An exploratory discussion withi
indicated it would be necessary for the Testing Laboratory
to participate in preparation of a control and test plan
to define a pilot test program.
Preparation of the control and test plan would cost about
Jand performing the test would cost about In
a ion, an engineer from the equipment manufacturer should
participate which may or may not be an additional cost.
In the next period, second preliminary reports will be
prepared on Item 1 and on Item 2 of Task II.
