INTRODUCTION This document is a Register of the CV numbers allocated by the Technical Valve Committee. The allocation of a CV number for a valve does not imply any general approval for the use of that valve in Service equipment. Reference should be made to the Services List of Preferred Valve for valves which are approved for general Service use, and to the E.V.S. publication or the T.V.C. Office for valves which may have limited approval. 2. CONTENTS The Register is divided into four chapters. 3. CHAPTER 1 (a) The first column gives the list of CV Titles in numerical order; (b) The second column gives the prototypes and possible substitutes. These are for general information and it should not be assumed that they are identical with the CV type. (In the case of CV valves with COM entered in the Specification column, and where more than one valve is listed, the name printed in italics or underlined is that to which the CV number was given.) (c) The third column gives the Authorities responsible for the preparation of the Specifications which are sub- sequently distributed by the T.V.C. Office. Abbreviation Authority A.D. .. .. Admiralty Surface Weapons Establishment. M.O.A. .. .. Ministry of Aviation, R.A.E., R.R.E. and S.R.D.E. SH .. U.K. Atomic Energy Authority, A.E.R.E. W.O. .. .. War Office. G.P.O. .. .. General Post Office, E-in-C (S). J.A.N. 1 .. U.S.A., J.A.N.1.A. and MIL-E-1B. Requests for copies of the MIL-E-1 MIL f Specifications should be made to TIL.1(b), Ministry of Aviation, Leysdown Road, Mottingham, S.E.9. The American name of the valve should be quoted in preference to the CV Number. COM. .. .. No specification issued. Apply to the maker for information. (d) The fourth column gives the functional type. 4. CHAPTER 2 (a) Column 1 gives, in alpha-numerical order, the commerical type numbers of valves which have been given CV numbers or are the equivalents of valves which have been given CV numbers. (b) Column 2 gives the maker's name. In cases of valves .bearing an old type Service name the originating authority is shown, e.g. ACR 14 gives W.O. (War Office) NT 2 gives A.D. (Admiralty) (N.B. The separate entry "NT 2 Hivac (CV2213)" refers to a different valve.) (c) Column 3 shows the CV title applicable to the given type designation. (i) Where the CV number is shown without brackets the two items are identical, e.g. (a) AC/HL CV.2811 (The CV number has been given to the commercial valve for Service store purposes.) (b) ACR 14 CV.1390 (ACR 14 is the old Service type number.) (ii) Where the CV number is shown in brackets the valve is for practical purposes the same as the CV valve but may have wider tolerances. 5. CHAPTER 3 This consists of a cross reference from the old Service Stores references to CV numbers. 6. CHAPTER 4 This consists of a cross reference of the Joint Service Catalogue Numbers (NATO Stock Numbers) and CV Numbers and vice versa. 7. VALVE AVAILABILITY THE INCLUSION OF AN ITEM IN THIS REGISTER DOES NOT IMPLY AVAILABILITY. 8.

    SSB Exciter Circuits Using a New Beam-Deflection Tube

    8/24/2008 7360 Circuits SSB Exciter Circuits Using a New Beam-Deflection Tube Practical Circuit Data for Modulation, Frequency Conversion and Detection BY H. C. VANCE K2FF Extracted from QST March 1960 The new beam deflection tube described here appears to be a bulb-full of versatility, with more applications than were visualized when the tube was under development as an improved type of balanced modulator. This article tells how the 7360 can be put to work in a number of ways in the amateur field, particularly in SSB transmission and reception. A new beam-deflection tube, the RCA-7360, incorporates novel design features which, with suitable circuits, allow it to be used in many kinds of applications with improved performance at frequencies at least as high as 100 megacycles. The tube was originally developed to provide a high degree of stable carrier suppression when used as a balanced modulator in single-sideband service. More than 60 dB of carrier suppression has been obtained with it as a balanced modulator in SSB exciters of both the filter and phasing types. It is of course equally valuable in double-sideband suppressed carrier service. Frequency conversion, product detection, synchronous detection, single-ended to push-pull phase inversion, switching circuits, fader circuits and compressor- expander-limiter circuits are among the many other interesting applications in which the unique properties of this new tube have been found to be valuable. In this article circuits will be described which make use of the 7360 as a balanced modulator, a frequency mixer and a product detector.

    High-voltage Pulsed Power Engineering, Fall 2018 Closing Switches Fall, 2018 Kyoung-Jae Chung Department of Nuclear Engineering Seoul National University Switch fundamentals The importance of switches in pulsed power systems In high power pulse applications, switches capable of handling tera-watt power and having jitter time in the nanosecond range are frequently needed. The rise time, shape, and amplitude of the generator output pulse depend strongly on the properties of the switches. The basic principle of switching is simple: at a proper time, change the property of the switch medium from that of an insulator to that of a conductor or the reverse. To achieve this effectively and precisely, however, is rather a complex and difficult task. It involves not only the parameters of the switch and circuit but also many physical and chemical processes. 2/44 High-voltage Pulsed Power Engineering, Fall 2018 Switch fundamentals Design of a switch requires knowledge in many areas. The property of the medium employed between the switch electrodes is the most important factor that determines the performance of the switch. Classification Medium: gas switch, liquid switch, solid switch Triggering mechanism: self-breakdown or externally triggered switches Charging mode: Statically charged or pulse charged switches No. of conducting channels: single channel or multi-channel switches Discharge property: volume discharge or surface discharge switches 3/44 High-voltage Pulsed Power Engineering, Fall 2018 Characteristics of typical switches A. Trigger pulse: a fast pulse supplied externally to initiate the action of switching, the nature of which may be voltage, laser beam or charged particle beam.

    Acta Polytechnica Vol. 49 No. 2–3/2009 Capillary Discharge XUV Radiation Source M. Nevrkla A device producing Z-pinching plasma as a source of XUV radiation is described. Here a ceramic capacitor bank pulse-charged up to 100 kV is discharged through a pre-ionized gas-filled ceramic tube 3.2 mm in diameter and 21 cm in length. The discharge current has ampli- tude of 20 kA and a rise-time of 65 ns. The apparatus will serve as experimental device for studying of capillary discharge plasma, for test- ing X-ray optics elements and for investigating the interaction of water-window radiation with biological samples. After optimization it will be able to produce 46.9 nm laser radiation with collision pumped Ne-like argon ions active medium.

    CIGRE-183 2019 CIGRE Canada Conference Montréal, Québec, September 16-19, 2019 The Research on the Key Equipment for 750kV Fixed Series Compensation in 3000m a.s.l. CHEN Yuanjun，ZHOU Qiwen，WANG Dechang，Gao Jian，Chen Wei, Zhang Daoxiong (1. NR Electric Co., Ltd., Nanjing 211102, China) SUMMARY The Qinghai 750kV fixed series compensation is officially put into operation in December 2018, it is located in the Qaidam area of China where the altitude is 3000m.In this paper, the high-altitude insulation calculation of the main equipment is carried out, and the power frequency withstand voltage, lightning impulse voltage, dry arc distance and creepage distance of each main equipment are proposed. Based on the project, we researched the key equipment such as spark gap and measurement system. According to the ANSYS simulation, the structure of the main electrode of the spark gap is optimized from ball-ball electrode to ball-plate electrode to make the self-trigger voltage be more stable. Considering the self-trigger voltage of the trigatron is up to 60kVpeak, the electrode structure of the trigatron is optimized to the structure with large curvature spherical design. The new trigatron has a better linearity and the maximum standard deviation is less than 0.6. In order to research the triggering characteristics, we completed the self-trigger test in the laboratory where the altitude is 0m, and fit the curve of the main gap air distance and the self-trigger voltage. Considering the altitude correction, we calculate the theoretical value of the main gap air distance according the self-trigger curve.
