FINAL SITE INSTALLATION
REPORT FOR THE MONTH OF JULY, 1971
During July, the installation work at the. final job site reached STATINTL
the point where no significant work could continue until the environmental
airconditioning system could be brought up to specification. There are a
total of five systems that require conditioned air:
The general room.
The_ stage jets
The electronic cabinets.
The optical system. f
The film cooling.
None of these systems were operational at the beginning of July.
,
During the munLLh the w~ils and ceiling of the clean room were
closed in by the room contractor, and various elements of the aircondition-
ing system were operated.
During this airconditioning startup period, problems were encountered
which delayed the conditioned air sstems
y performing to their specified
STATINTL levels. This, in turn, prevented= from completing the final adjustment
for some of the Stereocomparator subsystems.
While the airconditioning systems were being adjusted, there were
periods of high humidity which apparently have caused some external and
internal corrosion to the Stereocomparator.. The possible extent of the
internal damage to the Stereocomparator has not yet been assessed, since
some of the potentially affected systems can only be operated after the
airconditioning equipment is up to specification. At this time it is known,
however, that there are problems with the electronic logic packages.

concern is that there may be internal U. an to the optical systems or
interferometers. This can only be determined dur) opr rational tests.
By July 30 the airconditioning systems had stabilized to the point that:
1. The general room was operating over'a range of 700 to 720 F,
at about 60% relative humidity.
2. The stage jets were 'varying between 660,.a.n.d 730 F (between
3. The electronic cabinets, were,varying from,74? to 800
F, with

5. No information is available on the film cooling at this time.

The maintenance portion' of the diagnostic. computer program is being
used successfully to locate -problems in the electronic logic.
Although the installation work for the Stereocomparator during July was
hampered by a variety of problems of which some examples have been given
above, it is anticipated that August will be a much more productive period
since the airconditioning problems ' appear now to be coming under control.
