This plant housed the machinery' for the mass production of all receiver type vacuum tubes, and picture tubes, klystrons9 and detectors manufactured at NIT-160. The plant was transferred to Fryazino from Tashkent during World War II. Practically all of the departments of the plant were operated three shifts per day, six days per week. 5ee Enclosure A for a detailed layout of the Vacuum Tube Plant9 and Para. 3 of this report for the type of equipment9 hours of operation, number of employees, and type of product manufactured by various sections at this factory2 The following is a list of vacuum tubes mass produced it this tube plant.

The second year was devoted to producing the tube in quantity without regard , to rejects, and the third year was the time that the quality should be stressed. The 1951 norm required that 1000 ' usable ACR-1sbe produced. To get this number it was necessary for 15 to 20 tubes to be produced per day, six - days per week. The great wastage of the tubes was prin- cipally due to bad cathode materials, and to the fact that the screen material deteriorated rapidly due to contami- 25X1 nation by gas used in sealing the tubes. 1 25X1 I 125 tubes per day was the maximum number of ACR-1's that could be produced with the equipment in- stalled in the tube plant in March 1951. (b) Picture Tube ACR-10 (Identical to and copied from the British tube.) Mass pro- duction of this tube started in 1949. 2000 of these tubes were designed for production in 1951. 'Rejects of these tubes were normally about 30%; however, in July and August of 1951 the rejects were 100%01 was told to remedy the bad screens that were causing 100% rejections. !the screens were very dull due to the fact that gas, used to seal the tubes, was entering the tube when the bases were being sealed to the neck of the CRT. The gas was entering due to the fact that the 25X1 composition of the gas changed daily. Therefore it was Impossible to adjust the torch to make certain all of the 25X1 gas was burned at all times. The hydrocarbons injected 25X1 into the tube in this manner caused a rapid. deterioration of the screen material when the. tube was heated in the 25X1 evacuating process. 25X1 25X1 (c) 25X1 25X1 25X1 25X1 1 After this incident?production was-re- sumed at the normal rate.

Picture Tube VCR-1 (Identical to and copied from the Britieh tubeo) Mass'pro- duction of this tube started in 1949. 1000 to 1200 good tubes were scheduled for production in 1951, The reject rate of these tubes was approximately the same as that of the ACR-1 tubes, These tubes as well as the ACR-1 and ACR-10 tubes were delivered to an unknown office named .

Ian average of 600 tubes is being produced weekly 25X1 during 1952. This estimate is based on the fact that 89 25X1 tubes were produced on the 13th of Marvell 1952 and 130 were produced on the 14th of Ma'rch 1952. 1 'these tubes 25X1 were being made for use in civilian receivers, since the 25X1 Quality was too poor for use in military equipment. 1 I many more of those tubes could be produced SECRET Approved For Release 2006/08/08 : CIA-RDP82-00457R013300500007-6 e 25X1 Approved For Release 2006/08/08 : CIA-RDP82-00457R013300500007-6_ SECRET/SECURITY INFORMATION 25X1 - 3 - without expanding any of the plant's facilities, since there are 12 pump stands available for use three shifts per day; however, the stands are not operated every day. Instead they are operated for two shifts about four days per week as glass envelopes become available. Twelve-and Sixteen-Inch Kinescopes A total of 150-200 of these two types of tubes are produced each month. 1 The delivery of glass envelopes determined the number of he tubes produced. These tubes, are also made for use in civilian TV sets.

In February 1952 the klystron department was moved down to the first floor,where there was about four times the amount of floor space. The move was completed as rapidly as possible, and entailed the moving of all the old klystron-producing equipment as well as the installation'of additional eqipment. Two pump. stands capable of producing a total of 75 klystrons in a 24-hour 'period were moved,as was glass-to-metal-sealing equipment. An argument arose during the move. The argument was between ? the pumpmeister in the new klystron department and the pumpmeister in the old department, and came about because ? the new department pumpmeister wanted eight pumps rather than just the two that were previously used for klystron production. The new klystron department was in mass pro- 25X1 ? ductiqn in March 1952. 50 25X1 employees worked in the new department and 20 employees worked in the department when it was upstairs.

The exception 'e this rUle was the supply of coated cathodes. Thee were' sally delivered daily; however, appreximately 105,000 eftted eathodes were delivered in January 1952. These were all sealed in evacuated Jars. and stbred for later use. I 25X1 these had been made up during the cold dry winter petziod and wore to be used in tubes produeed during thilestmater Months. This was done due to the fact that the cathodes produced in the summer months were not any good since they wereeliroduced in a non- regulated room.

AT NII 160 4. During World War II a laboratory sponsored by Telefu ere was located at 37 25X1 25X1 Planufer Strasse, Berlin, and wa concerned with the develop- ment of dark trace picture tubes. The I boratory was moved to Neuenhofen near Neustadt on the 011a River,where it remained until it was dismantled by the Soviets. During this time the dark trace tubes were worked on as well ae was research on a eaRT capable of showing two different colored blips at the same time. (The difference in velocity of electrons striking a CRT screen determines the amount of penetration of the electrons; therefore, if a cascade screen Is made of two materials, that give off different colors when excited, it was thought possible to be able to use this system for identifying friendly and enemy aircraft. This system was never endorsed by the Soviets.) the development of the following type picture tubes worked on at NII 160 lin the Soviet Union: (a) The AglAp_j, INE_N9 Land ACR No 10 Picture tubes were being produced in a NII 160 laboratory at the rate of 30 per month of each type in October 1946. One of these three tubes was given the Russian nomenclature 440-2474,however,1 L The first work 25X1 done on these tubes by Germans at NII 160 consisted of re- placing the poor grade mica supports in the tube with ceramic supports. This substantially reduced the number of rejects. Laboratory production of this tube was dis- continued in late 1949, at which time the tubes went into mass production at the NII 160 tube plant. (b) The first six months at NII 160 were spent in remodeling the laboratory, converting the prodUction of electron guns for picture tubes from hand-made to machine-made processes. (0 Dark Trace Tube ,--------. ? In the spring of 1947 'assigned the task of developinfem 25X1 screen materials for a dark trace tube to be used for pro- jecting an image 1 meter square. This work consisted 25X1 mainly of a repetition of work in Germany. 1---ltime was spent trying te eevele efficient ways of coating 25X1 "Imm0 screen of the tuba. Much difficulty was experienced in evaporating a smooth layer of cadmium chloride on the plat, Slow progress was made on this problem until Nov- ember 1948.at which time the Soviet Chief of the Dark Trace Laboratory gave orders to develop and make ready for pro- duction a dark trace tube formerly developed at OSW. This tube was given the Russian nomenc1atureAmcse7 (the 10 is thediameter of the screen in cm, the Russian L means SECRET Approved For Release 2006/08/08 : CIA-RDP82-00457R013300500007-6 Approved For Release 2006/08/08 : CIA-RDP82-00457R01330050000715x1 SECRET/SECURITY INFORMATION ray or beam, K means kinescope, the Russian P designates PPI, the T designates dark tracepand the number 1 signifies that this is the first series of this type tube.) 25X1 the pressure for early production of this tube was a result of the Soviets'having developed and started production of a radar set designed to use this tube. Laboratory models of this tube were operating by January 1949. By the end of 1950 this dark trace tube had been developed to a place where it was more sensitive than those graphed on Page 670,Volume 22 of the MIT series of books 25X1 published in 1948. a r ue s 25X1 25X1 added sensitivity to the use o more pure screen crystals. Also by the end of 1950 the norm was set at 12 good tubes per month. To obtain this norm it was necessary for 100 tubes to be made monthly. Approximately 50 of these 100 were rejected by the 'NII 160 Dark Trace Laboratory. The ? remaining 50 left NII 160 by truck and then approximately two weeks later the Germans in the laboratory were notified how many of that 50 had been acceptable. F Fthe 25X1 dark trace tube Is scheduled for mass production in 1952. - The dark trace tubes made at NII 160 were tested using a test stand copied from the one described on Pages 666 and 667 of Volume 22, MIT Radiation Laboratory series books. 25X1 The exception to this equipment was that an at tube, manufactured by NII 602 L 25X1I was used for recording decay time rather than the pen and ink recorder described in Volume 22. sketehed the test stand set-up: 25X1 Candensar lens Mercury Zamlo haler A" erri,s4 /Ware A = A removable mirror.

The chief of this laboratory was a Soviet who returned from having studied the CBS system in the Uni.ted States. He claimed to be closely associated with Mr ldmaitkof CBS and was a very industrious engineer. F-1 25X1 25X1 the first series of 10 laboratory tubes were pro- uce y the last of 1950.

By 1949 the 7, 12,and 16-inch kinescopes had reached such a state of development that they were removed from lab- oratory development status and were transferred to the tube plant for mass production. I I 25X1 these tubes were designed and produced for civilian tele- vision sets. 1 Ithe tubes were 25X1 of very poor quality and had a low development priority. (f) (g) Metallic KinescuftE In the summer of 1950 the German engineeroMr Werner Ilugej was asked to survey all American electronic publications for the purpose of determining whether or not metallic kinescopes could be made at NII 160. Mr Kluge 25X1 scanned all of the literature, and then informed the Soviets that the NII 160 effort should be directed toward making 24-inch glass kinescopes rather than metallic kinescopes. In January 1951 the Soviets ordered the laboratory to start making a small metallic kinescope. I un 25X1 March 1952 the necessary machinery for the production of small metal cones needed in the production of metallic kinescopes had been completed. The tube being made was a copy of an RCA metallic kinescope which was obtained and_analyzed in 1951. 25X1 25X1 Rectangular Kinescopes. Rectangular kinescopes were to be developed in 1948; however, it was never possible to get any to work properly, so the project was dropped. It was first impossible for the glass bulbs to be made; consequentlypthe bulbs were obtained from Osram in East Germany. Finally the entire project was discontinued due to poor picture definition.

The MIT series in English was available to Soviet engineers in the spring of 1949 and was used by the Germans as well as - the Soviet engineers. Soviet translations of the MIT books were available for purchase in the first part of 1950 These were generally literal translations and contained numerous errors. There were instances where two Soviet books contained the information that was in one MIT book. An example of this is the information contained in Volume 22 of the Radiation Laboratory series. This volume is divided into two parts and a Soviet book is published containing each of these parts. Each of the Russian volumes costs approximately 12 rubles. All American technical publications were available for issue by the Institute library within two months of the date of publication. Any foreign publication desired by NII 160 engineers could be 'obtained through the Moscow Lenin Library in the event the book was not in the NII 160 library.
