This overview and collection of documents and other material related to the Office of Scientific Intelligence (OSI) offer a glimpse of CIA's overall contribution to the analysis of Soviet capabilities in science and technology during the Cold War. It is by no means intended to be definitive, or even complete, with respect to all the activities associated with the Agency's scientific and technological capability, analysis, and resulting report. It does, however, highlight some key events and selected activities that contribute to our understanding of the unique role OSI played in the Agency's history.

Thesis. The electrical characteristics of In/I/In and In/I/Pb superconducting tunnel junctions have been studied in detail. Since In does not readily form pinhole free oxide layers, a thin insulating dielectric was formed on freshly deposited In film by passing an electric discharge through an atmosphere of fluorocarbon gas. Junctions were then completed by depositing a thin counter electrode of In or Pb. The same process was used to prepare high resistance junctions with Au as the base electrode; these were not however, studied in detail. In/I/In and In/I/Pb junctions were produced with resistances in the range 0.01 ohms to 10/sup 10/ ohms at liquid helium temperatures. Low resistance junctions exhibited nonlinear electrical characteristics associated with good quality oxide'' superconducting junctions including (a) the dc Josephson effcct, (b) quasiparticle tunneling characteristics. (c) phonon structure and (d) inelastic tunneling phenomena. The magnitude of the Josephson current for In/I/In junctions agreed to within a few percent of the value predicted by strong coupling theory. Current voltage (I-V) and first and second derivative curves for In/I/In and In/I/Pb were compared with curves for Al/I/In and Pb/I/Pb junctions. Discrepancies between the characteristics can be, for the most part, explained on the basis of existing theories of phonon mediated superconductivity using recent data from inelastic neutron scattering studies of In. Nonlinear structure at voltages below the phonon spectrum was observed and is most likely associated with Kohn singularities. At higher voltages, second derivative curves exhibited resonances characteristic of CH and OH impurities in the barrier as well as a complex spectrum associated with the vibrational spectrum of the fluorocarbon dielectric. To better characterize this dielectric, a variety of surface analytic techniques were used to determine the complex index of refraction, the chemical composition and chemical homogeneity of the barrier. I-V curves for high resistance junctions were used to determine the potential at the metal-insulator interface.

An experimental study has been made 'of the energy transfer from a hot (T-5 x 10 K), dense (n -.10 cm ) 6 0 16 -3 deuterium plasma containing a strong magnetic field 4 (8-10 Gauss) brought into sudden contact with a cold wall. The energy flux from the plasma to the wall was measured using a thin film, fast rise-time bolometer. The construction, calibration, and theory of this bolometer are described. The experimentally measured energy flux was compared with a theoretical prediction employing classical plasma transverse thermal conductivity. The measured energy flux is found to be about 1.5 times that predicted by classical plasma theory. The measured plasma ftransverse thermal conductivity exhibits the functional dependence on temperature, magnetic field, and density that is expected from classical plasma theory. The extent of damage to the cold wall surface was also measured using a scanning electron microscope to examine various wall samples exposed to the plasma. The observed surface damage to a copper wall sample was in reasonable agreement with the predicted damage due to sputtering. The damage to the surface of a stainless steel wall sample was considerably greater than predicted by sputtering.

Thomson scattering was used to obtain eloctron temperature and density profiles in deuterium plasmas produced by strong collisional shock waves. The transverse shock speeds were 3 to 25 cm/ usec in 50 to 100 mTorr deuterium. Ruby laser light was incident at a right angle to the axis in the midpoint of the annular gap of an electromagnetically driven coaxial shock tube.and scattered 9 light was collected at 90 degrees. Plasma created by reflecting a strong shock from a dielectric wall was also studied. It is found that the plasma electron temperature (10-30 eV) is much less than the ion temperature (100-500 eV) as is predicted by theory for the early life of the plasma. Electron-lon Coulomb colllslonal temperature relaxation does not occur during the times of observation (3-4, AA sec). Electron heating in the plasma is caused primarily by Ohmic dissipation of currents in the shock structure and piston. Plasma densities (0.5-3.5x1016 cm-3) agree well with shock theory predictions. For gas ionizing shocks, good agreement with collisional theory is found for the electron temperature.

Diffusion in the silver-zinc-cadmilth system was investigated at 6000C with semi-infinite, vapor-solid couples in order to evaluate intrinsic diffusion coefficients and interdiffusion coefficients in the alpha and beta phases. Intrinsic diffusion coefficients were determined at several composition points.in the alpha phase region along concentration lines of 11 at. pct Zng 18 at. pet. Zns 5 at. pct. Cd and 9 at. pct. Cd. Interdiffusion coefficients in the a phase were determined at several points of intersection of various composition paths; these composition points of intersection were along lines of constant zinc-to-cadmium concentration ratios of 3.8, 1.8 and 1.2. All two-phase diffusion couples developed planar B/a interfaces. Intrinsic coefficients were computed at three composition points in the beta rega corresponding to a silver concentration of approximately 55 at. pct. Intrinsic coefficients for B alloys are two to three orders of magnitude larger than those for alpha alloys.

E/B decay branching ratios were measured for decays from Eu, 14 3 1 4 39 Sm', and 1 4 39Gd. y -y triple coincidence experiments were performed to get relative positron feedings to respective daughter levels. X-y coincidence measurements were done for 1459Gd decay to obtain relative electron capture feedings and these feedings were inferred from singles intensities for 143Eu and 1439Sm decay. 143 The decay schemes of Eu and 1439Sm were also studied, and 12 143 levels were reported in Pm as well as 16 levels in 143Sm. Data were also gathered relevant to 14ompm decay and a B+ endpoint for 66Ga decay is reported. B decay theory is discussed in some.detail, especially concerning the implications of E/B decay branching ratios. It is shown that anomalous ratios can only occur for higher order terms 'in allowed transitions or if a pseudoscalar force is present. Neither possibilities were hitherto eliminated experimentally. Among 15 measured /B branching ratios, two were significantly anomalous. The transition to the 808.5 keV level in 145Eu was anomalous by a factor of 24 and the transition to the 1173.1 keV level in 143Pm was anomalous by a factor of 4.9. Each case'involved a similar hindered.
