MARSDEN U. S. DEPARTMENT OF COMMERCE NATIONAL BUREAU OF STANDARDS THE NATIONAL BUREAU OF STANDARDS Functions and Activities The functions of the National Bureau of Standards are set forth in the Act of Congress, March 3, 1901, as amended by Congress in Public Law 619, 1950. These include the develop- ment and maintenance of the national standards of measurement and the provision of means and methods for making measurements consistent with these standards; the determination of physical constants and properties of materials; the development of methods and instruments for testing materials, devices, and structures; advisory services to government agencies on scientific and technical problems; invention and development of devices to serve special needs of the Government; and the development of standard practices, codes, and specifications. The work includes basic and applied research, development, engineering, instrumentation, testing, evaluation, calibration services, and various consultation and information services. Research projects are also performed for other government agencies when the work relates to and supple- ments the basic program of the Bureau or when the Bureau's unique competence is required. The scope of activities is suggested by the listing of divisions and sections on the inside of the back cover. Publications The results of the Bureau's research are published either in the Bureau's own series of publications or in the journals of professional and scientific societies. The Bureau publishes three periodicals available from the Government Printing Office: The Journal of Research, published in four separate sections, presents complete scientific and technical papers; the Tech- nical News Bulletin presents summary and preliminary reports on work in progress; and the Central Radio Propagation Laboratory Ionospheric Predictions provides data for determining the best frequencies to use for radio communications throughout the world. There are also five series of nonperiodical publications: Monographs, Applied Mathematics Series, Handbooks, Miscellaneous Publications, and Technical Notes. A complete listing of the Bureau's publications can be found in National Bureau of Stand- ards Circular 460, Publications of the National Bureau of Standards, 1901 to June 1947 ($1.25), and the Supplement to National Bureau of Standards Circular 460, July 1947 to June 1957 ($1.50), and Miscellaneous Publication 240, July 1957 to June 1960 (includes Titles of Papers Published in Outside Journals 1950 to 1959) ($2.25); available from the Superintendent of Documents, Government Printing Office, Washington 25, D.C. NATIONAL BUREAU OF STANDARDS ISSUED JUNE 3, 1963 TABULATION OF PUBLISHED DATA ON SOVIET ELECTRON DEVICES Charles P. Marsden NBS Technical Notes are designed to supplement the Bu- reau's regular publications program. They provide a means for making available scientific data that are of transient or limited interest. Technical Notes may be listed or referred to in the open literature. For sale by the Superintendent of Documents, U.S. Government Printing Office Washington 25, D.C. - Price 45 cents Foreword This tabulation of published data on Soviet electron devices has been prepared as part of the National Bureau of Standards Electron Devices Data Service. Established in 1948 to provide technical data on radio tubes to members of the Bureau staff, the service has since been extended to other scientists and engineers in government and industry. In the course of the program, a large volume of information on tubes, transistors, diodes, and other electron devices has been accumulated on punched cards. To make this information more readily available, a system has been worked out for automatically tabulating the data in handbook form. Previous tabulations include Tabulation of Data on Receiving Tubes , NBS Handbook 68 (1959); Tabulation of Data on Micro- wave Tubes , NBS Handbook 70 (1961); and Diode Source Book (published by Semiconductor Products magazine, (1961). The present tabulation is the result of compilation efforts ex- tending over the past four years. All the included information was taken from published specifications, and every effort has been made to ensure accuracy and completeness. However, the Bureau cannot assume responsibility for omissions nor for results obtained with these data. A. V. Astin, Director. II Contents Page 1. Introduction, 1 2.

Marsden This tabulation includes published data on Soviet electron devices as collected from various publications, mostly handbooks pub- lished by the various ministries and institutes of the USSR. Information is given on all active devices ranging from receiving to micro- wave devices, semiconductor devices, and various miscellaneous devices such as, for example, photographic flash tubes and thermis- tors . 1. Introduction The increased circulation of published literature from the USSR and the importation of Soviet equipment has created a need for factual information on Soviet electron devices. To satisfy this need, the National Bureau of Standards Electron- Devices Data Service has prepared the present tabulation in a format that could be reproduced directly from punched cards. The advantages of the use of these cards include the elimination of errors possible with other methods of reproduction, flexibility in adding or deleting information, and uniform columnar presentation.

    Vacuum Tube Theory, a Basics Tutorial – Page 1 Vacuum Tubes or Thermionic Valves come in many forms including the Diode, Triode, Tetrode, Pentode, Heptode and many more. These tubes have been manufactured by the millions in years gone by and even today the basic technology finds applications in today's electronics scene. It was the vacuum tube that first opened the way to what we know as electronics today, enabling first rectifiers and then active devices to be made and used. Although Vacuum Tube technology may appear to be dated in the highly semiconductor orientated electronics industry, many Vacuum Tubes are still used today in applications ranging from vintage wireless sets to high power radio transmitters. Until recently the most widely used thermionic device was the Cathode Ray Tube that was still manufactured by the million for use in television sets, computer monitors, oscilloscopes and a variety of other electronic equipment. Concept of thermionic emission Thermionic basics The simplest form of vacuum tube is the Diode. It is ideal to use this as the first building block for explanations of the technology. It consists of two electrodes - a Cathode and an Anode held within an evacuated glass bulb, connections being made to them through the glass envelope. If a Cathode is heated, it is found that electrons from the Cathode become increasingly active and as the temperature increases they can actually leave the Cathode and enter the surrounding space. When an electron leaves the Cathode it leaves behind a positive charge, equal but opposite to that of the electron. In fact there are many millions of electrons leaving the Cathode.

  • Early German and American Radar Transmitter Technology 1
    Copyright 2002 by Hans H. Jucker. Published in the Tube Collector Association Bulletin, Medford OR 97501, U.S.A. October 2002 Early German and American Radar Transmitter Technology Initially radar engineers worked with commercially available transmitter tubes. The very high voltage operation in radar transmitters caused serious positive ion bom­ bardments of the cathode. Therefore only tungsten cathodes or thoriated tungsten cathodes with their rather limited electron emission were sufficiently robust for this service. In 1937 Dr. Felix Herringer of the Lorenz electron tube laboratory mastered the development of an oxide cathode tube, suitable for pulse modulated UHF radar transmitters. The C. Lorenz company filed 1938 for the new type of tube, the patent Nr. 862782 “Anodenimpulsmodelung bei Röhren mit Oxydkathode” The photo shows the first laboratory sample of the Lorenz DS 323 pulse type UHF triode developed 1937. The DS 323 was the first pulse type transmitter tube with oxide cathode, suitable for radar transmitters. The oxide cathode with the higher electron emission (>5 amps. plate saturation current) made it possible to generate much higher RF output powers. The power dissipation of the heavy plate construction, containing several heat sinks, was 75 watts. The tube didn’t need a getter because of the tantalized plate surface. In 1938 Dr. Gotthard Mueller of the C. Lorenz labora­ tory at Berlin, developed with two DS 323 tubes a pulse modulated push pull transmitter for the 500 MHz band. The C. Lorenz company filed for this new kind of transmitter on 10th April 1938 the patent Nr. 767453 “Anordnung zur Erzeugung bzw.

  • Secret Radar Valve the EF50 Part 1
    The secret radar valve the EF50 Part 1 By Graham Dicker Introduction Over the last 50 years or so I have had a love & hate affair with the EF50, having said that the more that I work with this valve the more I can appreciate the secrets that it’s design unravel as time progresses and information comes available. I am sure that this wonderful valve has been overlooked by many for all kinds of projects by the home constructor. In this two part series I will attempt to unlock some of it’s characteristics, idiosyncrasies that I have discovered. There is plenty of information on the web about this so I don’t intend to re-hash what you can already find, but concentrate my efforts on what is not so obvious , and harder to find and understand. Some history along the way is always a good thing. The EF50 is also known as the VR91 CV1091 ARP35, later versions are the EF54, EF55 and the EF90. The valve is a fully controlled pentode, and as such was used in a number of FR applications the most famous as an IF strip. Prior to WW2, most radio communication work was in the HF band (below 30mhz), most RF valves at that time tended to perform quite poorly at 30mhz and above, while being researched and being used communication had not extended above 100mhz at the time due to poor valve gains at these frequencies. There were two main issues, the first was caused by the inductance and capacitance of the internal leads, the second was due to the finite time that the electrons took to travel between the valve electrodes.

  • The Vacuum Tube
    The Vacuum Tube by Ludwell A. Sibley 102 McDonough Rd. Gold Hill, OR 97525-9626 Please include SASE for reply, Copyright © 2000 Lunwell A. Sibley The Acorn Tube Innovations in tube technology were often important at the time of introduction but faded into disuse after a few years. A vivid example of this effect is RCA's "acorn" tube design, which greatly eased the problem of building equipment for VHF and low-UHF frequencies during the late '30s and early '40s. This unique design attacked the traditional limitations of tubes at high frequencies by shrinking the dimensions of the elements, adopting a relatively tiny all-glass bulb, and using thick radial element leads of unusually low inductance and capacitance. B. J. Thompson and G. M. Rose of RCA published articles describing an experimental triode and tetrode in 1933-34 [1, 2]. Development continued, yielding a tube in the form that we recognize as the "acorn" [3]. It, and Bell Labs' "doorknob" tube, were the first U. S. physical designs to break free of the "light-bulb" origins of the vacuum tube. The first commercial tube in the line, and the most important by far, was the 955 triode, announced in March 1935. It was promoted as usable up to 500 MHz. RCA sold it initially under the "RCA-De Forest" brand, which it was then using for amateur- market transmitting tubes and CRTs. The earliest tubes have a rounded dome, more nutlike than the squared-off bulbs of later production. The 955 was accompanied by the 954 sharp-cutoff pentode.
