Plans for this facility are on the drawing board and a plant site
has already been chosen. The R. S. material claims a higher image
reproduction quality with superior retention of information when
compared to E.K.'s 2430. This product differs from conventional
photographic films in that the R. S. material utilizes Titanium
Dioxide rather than silver salts as the photo conductor. The metalic
silver which provides the final image density is introduced during
processing which results in a 37 percent saving of this metal in
the final positive (compared to E.K.'s 2430). The latent image of
the R. S. material begins to decompose immediately after exposure
and, therefore, processing or stabilization must be accomplished
within minutes. A printer/processor to accommodate this product is
also under development. A unique feature of the R. S. material is its
ability to be resensitized and over printed, thus such things as grid lines,
annotations and/or titling can be added. Because processing or stabili-
zation must be accomplished almost immediately after exposure and due
to the slow inherent speed of the photo conductor, major emphasis is
placed upon the material as a duplicating, rather than taking, film.
Research on the taking aspect continues. Promising indications are that
the R. S. material could become a non-silver product in the near future.
The tonal range of the present material goes from 0.6 to a 5.0
density and the spectral sensitivity can be controlled by filtration and
the use of different photo conductors. The image appearance is similar
to that of 2430 except that the clear areas are slightly milky due to the
dispersion of the photo conductor, which remains in the material. The
R. S. material is manufactured in white li ht and is sensitized by a
25X1A period of dark storage prior to exposure. stated: "Because
of the high quality of our originals, we are at t e danger point for dupe
stock resolution." As is expected after such a statement, a higher
resolution retention capability than 2430 is claimed by the R. S. material.
Pending contract signature, in about 12 months, _ expects to deliver, 25X1A
25X1A probably to - an R. S. type printer/processor with a dual gamma
capability. The printer portion of the unit will be a standard Niagara
printer which will limit the maximum production rate to 100 feet per
minute.
~ is now working to develop an R. S. printing paper. Other projects
include a table top processor to make chips in both paper and film form.
M is interested in a. film chip product from such a machine.

Manufacturing techniques employed to produce the KH-4A lenses and
those used for KH-4B lens production were compared and the improvements,
such as purchasing all lens blanks from the same meld, were discussed.
The improved techniques resulted in an increase of approximately 45 1/mm
between an average first and second generation lens. Some little known
facts which were mentioned are:
a. An emery slurry is the abrasive used to grind the blank.
b. An iron oxide slurry is employed to polish the lens.
c. The air spaces employed between elements must be vented
in order to accommodate the pressure variation at different altitudes.
Small air filters are installed in these vents to keep the air spaces
free of foreign particles.
d. The KH-4 and Optical Bar lens barrel which are made of
a Beryllium/Titanium alloy,are not an _ product but are purchased 25X1A
on the open market.
Our walk-through-tour began at the computer facility, proceeded
to the lens production area, continued to the lens bench test department
and terminated at the environmental test area. This last area-contains
collimator equipped test tanks large enough to accept an entire camera
system for adjustment and testing.
25X1A 5.rf Optimum Gamma: gave a briefing on what he
termed optimum gamma processing". Conventional three level Trenton
25X1A processing produces gammas of 2 to 3 on 3404 while _ contends that
the "optimum" gamma on 3404 for our use is 1.4. This lower gamma is
said to produce:

25X1A 7. Systems: Mr. presented a briefing in which he
compared the KH-4B to the KH-4A. Both design and performance differences
were discussed in his extremely comprehensive briefing. Following lunch
we toured the final check-out facilities for the KH-4 and Optical Bar
cameras. Actual systems undergoing test were operated so that. their
movement could be observed.
8. Time: The tour of the facilities was extremely well-
planned for maximum time usage. Our itinerary was so tight that in order
to conserve time, Friday's lunch was served in a room adjoining that in
which we received the pre-lunch briefing.

b. The _ approach is now aimed toward the reproduction
quality aspect of our procedure. The big push is already on to
sell us the R. S. material.
c. In some respects the non-technical personnel which comprise
the majority of the MSWG receive a slanted view of the briefing
presentations such as on "Optimum Gamma" and the R. S. material.
That we are presently having our mission material processed 'dual
gamma' was news to most of our group, several of which
became upset that this change had not been
approved by all building components. They were likewise upset that
no studies have been accomplished prior to this change in procedure.
From the TSSG standpoint, this looks bad in eyes even though
such changes have building coordination and approval. The old
addage - "a little knowledge is a dangerous thing" - holds true in
situations like this.
