It was found that conditions for perfect geometric and chromatic *focusing of the d1f- fraction line can be met readily. General considerations and computa- tions for a given experimental setdo are described. Several rules are suggested for optimum choice of the parameters for simultaneous focusing of a pair of lines. An achromatic camera which is suitable for this sort of measurement is described.--The profile of a line with 0 a 74.3 degrees (the 331 li:ie of annealed aluminum) obtained iwith an achromatic arrangement and that obtained by means of an.ordi-.

An absorbing rod, black for thermal and transparent for epithermal neutrons, is inserted to different depths of the channel. The boundary condition throughout the channel length is -_,onsidered as some operator (Kl, K2) affecting the neutron density function. It is assumed that the boundary,conditions on the channel. surface, on the spot i-hiere the absorb- ing rod terminatos, vary discontinuously. The solution is written down as the sum of products of trigonometric functiono (dependence on height) by some combinat'. Ions of cylindrical functions, satisfying the boundary conditions on the external re- actor surface. The operators K, and K2 are represented using trigonometric func- Card 1/2 S/058/632/000/003/036/092-~ Neutron density distribution in... A061/AIOI tions.

Bond (Ref.4), Preuss (Ref,5) and Mayer (Ref.6) studied the influence of tempering on the electric resistance of thin layers. Their results show that the electric resistance of thin metal layers is subjected to changes during the natural ageing or tempering and that these changes occur as a restf1t. of changes in the strut-,ture of the layer. Tempering may also lead to destruction of the layer. The authors studied the pronounced increase of the electrical resistance of thin tellurium layers in the temperature range 190*C. The structural changes occurring in such a case were investigated as a function of the resistance of a thin layer on the frequency of the current which passes through the layer. The measurements were carried out on 10 x 15 mm thin layer specimens of spectrally pure tellurium produced by vactium evaporation on a glass base at room Card. 1/3 8h9L8 Z/037/6o/ooo/oo6/ool/OlO E073/E535 Irreversible Change in the Electric Resistance of a Thin Tellurium Layer During Artificial Ageing temperature. The contacts were obtained by depositing a thicker layer of tellurium at the end of the specimen by repeated evapora- tion in vacuum and screening of the centrinl part of the specimen. The current was fed in by means of inechanically clamped copper electrodes ensuring a good contact, as was ascertained by means of resistance measurements at, lour frequencies. The specimens ivere heated in an electric furnace. The d.c. resistance was measured by means of a resistance bridge, the a.c. resistance was measured by means of a loss angle meter RFT, type 193, in the frequency range 150 kc/s and 10 Mels. The changes in the d.c. resistance in most cases did not vary by more than 3% of the value at the beginning of the measurements. After terminating the measurements, the tellurium layer was evaporated and the conductivity of the glass base measured ; this was found to be negligible compared to the conductivity of the layer. The results obtained for three heating cycles and also the results of the frequency measurements before and after the first heating cycle and after the third heating cycle are given.

The resistance of the amorphous regions increases irreversibly and so does the DC resistance of the thin layer. There are 2 figures and 14 references: 2 German and 12 English.

TITLE. Photovoltaic Effect on. a Thin Film of Cadmium Telluridia PERIODICAL: Ceskoslovensky"'6asopis pro fysiku, 1961, No.2, pp.14i-148 TEXT. The photovoltaic effect of cadmium telluride has rficently aroused interest because of the possibility of its use in tiolar batteries. Various authors reported measurements of the photo- voltaic effect between cadmium telluride and various thin nurface layers. The present authors studied the photovoltaic effoct of thin films of p-type cadmium telluride evaporated onto a motallic substrate. The cadmium telluride was evaporated onto a layer of either tellurium or aluminium and the second contact was formed by metallic cadmium. The cadmium telluride contained less than 0.001% of Cu, Pb and Si. The evaporation was carried out at room temperature at 10-5 mm Hg. The area of the layers was about 0 5 or 1 cm2 and the thickness 19.611 and 0,2 ~t, The resistivity 0~ the layer was approximately 10' ohm cm. Three samples were used for the measurements: a) Te-CdTe-Cd (smaller resistance); b) Te-CdTe-Cd (larger resistance); c) Al-CdTe-Cd. Card 1/3 23071 Z/037/61/000/002/003/003 Photovoltaic Effect E133/E435 All the cells showed non-linear d.c. characteristics both in the dark and under illumination, The maximum resistance occurs when the cadmium contact is positive. This is in agreement with the aSSUMption of a p-type layer of Cd,re which is also in agreement with the thermoelectric and photoelectric e.m.f.'s. The samples ,were highly unstable. From a.c. measurements of the resistance and capacity, it seems established that a barrier layer of the Schottky type exists in the cells. The internal resistance ford from measurements of the photoelectric tD.m.f. was 4.65 x 10 ohm for sample (a). . The photoelectric ciu:-rent has been found linearly proportional to the absorbed radiative energy within the full spectral range. The photovoltaic e.m.f. increases linearly with absorbed energy up to about 10 W but shows a tendency to saturate at higher energies. Samples studied by the present authors did not show a maximum in their photosensitivity within the range of the wavelengths investigated, while commercial CdTe cells do show a maximum within this range.

The specimens on which the measurements were carried out were produced by vacuum deposition of a thin film of silver at the ends of 4a glass base and, following that, depositing at a vacuum of 10- mm Hg a thin layer of cadmium telluride. The thus produced specimens hadl. a p-type conductivity. At the spots where the deposited thin cadmium telluride lay*r covers the silver layer diffusion of silver into the cadmium telluride may occur. both at elevated and at normal temperatures. The result of diffusion is a visible change in the absorption of light if the layer is transparent or there is a change in the thickness of the layer, which can be determined from the shift of the interference rings in Card 1/3 Diffusion of silver in a thin ... Z/037/62/000/001/007/007 9073/E535 monochromatic lights Diffusion of silver into the thin cadmium telluride layer causes an increase in the thickness of the layerg which is probably due to an expansion of the crystal lattice, This may damage or completely destroy the layer at the points of contact,, i.e. at points where the silver layer is covered by a layer of cadmium telluride. "Jumps" in the interference rings indicate that the "diffusion front" proceeds from the two contacts to the middle of the layer, The diffusion depth y was found to be proportional to the square root of the diffusion time t and it can be expressed by the equation of C.
