Study of high power electrostatically focused klystrons( Book )

2 editions published between 1966 and 1967 in English and held by 2 WorldCat member libraries worldwide

A periodic electrostatic focusing structure optimized for a beam perveance of .0000015 has been designed utilizing the resistor network analogue in conjunction with a digital computer. The lens electrodes are at cathode potential and are located between each cavity. Also a .0000015 perveance gun was designed with the resistor network. The same gun was checked by applying different modulating anode voltages. Buncher and output cavity models have been built and cold-tested. The design of the experimental tube has been completed and parts have been ordered. (Author)
Non-Periodic Helix TWT Study( Book )

1 edition published in 1980 in English and held by 1 WorldCat member library worldwide

The purpose of this contract was to determine the feasibility of using various techniques to increase the operating voltages and peak power levels of helix type traveling-wave tubes. An oscillation suppression technique has been proposed which has application at high voltages and high frequencies. Based on a theoretical analysis of loading in transmission lines, calculations have been made which predict the presence of stopbands. Cold tests were performed which verified the accuracy of these calculations. A tube was built and tested. The test results indicate that the modes exist as predicted in cold test. Further testing is required to determine whether or not the stopband exists for hot test operation
Development of a lightweight troposcatter power amplifier( Book )

1 edition published in 1968 in English and held by 1 WorldCat member library worldwide

The primary objective of the program was to design and develop a lightweight troposcatter transmitter system including antenna. The transmitter was to make use of a newly developed Electrostatically Focused Klystron Tube. State-of-the-art technology common in the aerospace industry was to be utilized to reduce size and weight of the equipment. The result of the program was the development of a transmitter system weighing approximately 100 pounds. The RF power output was 1 KW CW over the 4.4-5.0 GHz troposcatter band. The weight includes a 6 foot diameter parabolic dish of novel design. This report describes the development program and outlines the technical tradeoffs that were necessary during the design phase. Recommendations are made for future systems. (Author)
Pulse Compression Filters and Dispersive Delay Lines( Book )

1 edition published in 1970 in English and held by 1 WorldCat member library worldwide

The report describes the design and construction of surface acoustic wave pulse compression-expansion filters which operate in the UHF microwave frequency range. A matched pair of filters having a center frequency of 700 MHz, an expanded pulse length of one micro-second, and a bandwidth of 300 MHz was built and tested to demonstrate the procedure. (Author)
Design of an octave bandwidth high power, s-band injected-beam crossed-field amplifier( Book )

1 edition published in 1967 in English and held by 1 WorldCat member library worldwide

Research and development were conducted to achieve a design of an octave bandwidth injected beam crossed field amplifier. This tube is rated at 2 kw minimum power output at 40% efficiency, with the capability of being pulsed to an objective level of 10 kw. The crossed field amplifier is an inherently high efficiency device whose bandwidth is primarily dependent upon the dispersive nature of the slow-wave structure. It has been shown in an existing P-Band crossed field amplifier that the helix has the capability of meeting the high power octave bandwidth requirement. Other existing crossed field amplifiers have exhibited moderate pulse capabilities, and gun modifications would be necessary to maintain good optics under the pulse conditions. The overall tube design is heavily dependent upon the type of delay line structure utilized to fullfill the program requirements. Many slow-wave structures were investigated and examined for bandwidth, interaction impedance, thermal capability and ease of mechanical construction. This resulted in the choice of the modified helix mounted on a cooled dielectric rod. The mechanical design was then developed, resulting in a small lightweight tube suitable for operation in an airborne environment, and with the potential for being economically produced at a high yield.

Development of a ku-band crossed-field amplifier (500 watt tube)( Book )

1 edition published in 1966 in English and held by 1 WorldCat member library worldwide

This is the Final Report on the development of a high gain, high power crossed-field amplifier of linear format operating at K sub u-band. This report first details the electrical design of the tube. It was derived from a design used in another tube at a lower frequency. A large-signal analysis computer program is used to verify the design. The delay line and the electron gun were also derived from the lower frequency tube. The depressed collector used in the tube was also developed by computer analysis. The mechanical design of the tube, based on prior experience in developing similar devices, is given in detail. Several innovations have been incorporated in this design. A permanent magnet design was developed that has the desirable feature of being completely shielded. The magnet design was developed using the Litton Resistance Network Analogue. The constructional details and hot test results are given for the three operational tubes constructed. (Author)
Establishment of manufacturing methods for crossed-field amplifiers at p-, s- and x-bands( Book )

1 edition published in 1967 in English and held by 1 WorldCat member library worldwide

Three tubes in a family of high power, high efficiency, broadband, injected-beam crossed-field amplifiers have been developed. These tubes are capable of over 1 kW CW output power in the frequency range of P-, S- and X-bands. Small quantities of each type have been production fabricated and submitted to extensive electrical and environmental tests. The basic theoretical analysis of the characteristics of this class of microwave tubes have been verified with the experimental data. Electrical, mechanical and procedure specifications were established. Data was collected on many tubes to establish the validity of the specifications. Cost reduction has been gained through the use of common construction methods and through the use of new manufacturing methods
