This book was released on 1966 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: This contract was in essence a feasibility study of a new interaction scheme for extracting beams. The proposed interaction should take place when an array of small electron beams are collected by a thin metallic film deposited on the surface of a dielectric. The interaction takes place between the conduction current and the RF electric field within the volume of the thin metallic film. An approximate theoretical analysis of the problem is presented and the power output which might be expected from such an interaction is calculated. A practical method of modulating the array of electron beams is presented. A preliminary experiment is reported which demonstrated that the thin film is not damaged by the electron beam. Design and fabrication problems of the electron gun and beam modulator are discussed. (Author).

This book was released on 1985 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: We investigate through numerical simulation the advantages of a multicavity linac for improving the quality of the electron beam due to the technique of phase synchronism. This will also increase the shunt resistance of the accelerator which is desirous if very high energy is the goal. However, if a particular energy is required, then the shunt resistance must be held constant. Fortunately, a cavity's quality factor, Q, is approximately inversely proportional ot its length if its aspect ratio is much less than one. Therefore, the shunt resistance can be controlled by varying the length of the cavities.

This book was released on 1992 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objective of our research for ARO is to develop devices that have the potential for being compact generators of submillimeter-wave radiation. (1) The high-harmonic gyro-frequency multiplier, which is an efficient generator of high frequency rf, will be tested at the tenth-harmonic in our rebuilt test-stand. (2) High-power harmonic gyro-TWTs can be designed to operate in high order modes in large size waveguide by using the marginal stability design criterion. (3) Our high power, second-harmonic TE2 1 gyro-TWT, which is predicted to generate an order of magnitude higher power than state-of- the-art fundamental frequency gyrotrons, has been fully designed and construction is well underway. (4) The interaction strength in our high-harmonic CARM increases as the electron Larmor radius moves closer to the wall radius as the magnetic field is lowered towards a grazing intersection. (5) A high performance amplifier is predicted to result from our initial gyro-klystron experiment ...

Book Synopsis Physical Foundations of the Millimeter and Submillimeter Waves Technique V.2 by : V. P. Ščestopalov
Download or read book Physical Foundations of the Millimeter and Submillimeter Waves Technique V.2 written by V. P. Ščestopalov and published by VSP. This book was released on 1997-08 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The developments in physics, biology and astronomy, as well as radar and communication technology, remote sensing and spectroscopy have led to a sharp increase in the investigations of electromagnetic millimeter and submillimeter waves with the lengths 10--1 and 1--0.1 mm. These volumes reflect the results of extensive research in this field and attempt to destroy stereotypes established during the long years of large-scale modeling in the millimeter and submillimeter wavelength ranges and to develop new concepts. The first volume (Open Structures) deals with the results of theoretical and experimental studies of open electrodynamic structures (open waveguides, open resonators, diffractional gratings) allowing the determination of the characteristics of various devices used in millimeter and submillimeter technology. The second volume (Sources. Element Base. Radio Systems: Novel Scientific Trends) presents the problems of creating independent units and radiosystems of the millimeter and submillimeter wavelength ranges and the justification of their physical operating principles. This includes the mechanism of generating volume waves by electron flows moving close to a grating, excitation of fields in open resonators and waveguides with inclusion, and other phenomena.

This book was released on 1995 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of our research is to investigate the physics as well as to develop the technology of compact submillimeter-wave devices.(1) A revolutionary new device, the gyro-frequency multiplier, which can potentially generate 50 kW at 1-2 Thz by using a 140 GHz gyrotron as its input source, has been tested in our laboratory. (2) Our second-harmonic gyro-TWT amplifier, which is based on our recent marginal stability design (MSD) procedure, yielded extremely good results, including a record setting output power of 207 kW, with 13% efficiency, 16 dB saturated gain, 2% bandwidth and was completely stable. (3) The MSD procedure was also used to design two other stable, high performance amplifiers: a 1 MW, 140 GHz, third harmonic gyro-TWT and a 100 kW CW, 95 GHz, TE(01) gyro-TWT. (4) We have also begun a major new program to develop high power, ultra-wideband prebunched FELs for radar applications using a photoemitted rf gun (5) We have also continued to construct a high-performance 250 kW CW, 33.2 GHz TE(01)TE(02) gyroklystron amplifier and begun a 70 kW CW, 95 GHz, third harmonic, smooth bore gyroklystron amplifier program.

Book Synopsis Electron-Beam Technology in Microelectronic Fabrication by : George Brewer
Download or read book Electron-Beam Technology in Microelectronic Fabrication written by George Brewer and published by Elsevier. This book was released on 2012-12-02 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electron-Beam Technology in Microelectronic Fabrication presents a unified description of the technology of high resolution lithography. This book is organized into six chapters, each treating a major segment of the technology of high resolution lithography. The book examines topics such as the physics of interaction of the electrons with the polymer resist in which the patterns are drawn, the machines that generate and control the beam, and ways of applying electron-beam lithography in device fabrication and in the making of masks for photolithographic replication. Chapter 2 discusses fundamental processes by which patterns are created in resist masks. Chapter 3 describes electron-beam lithography machines, including some details of each of the major elements in the electron-optical column and their effect on the focused electron beam. Chapter 4 presents the use of electron-beam lithography to make discrete devices and integrated circuits. Chapter 5 looks at the techniques and economics of mask fabrication by the use of electron beams. Finally, Chapter 6 presents a comprehensive description and evaluation of the several high resolution replication processes currently under development. This book will be of great value to students and to engineers who want to learn the unique features of high resolution lithography so that they can apply it in research, development, or production of the next generation of microelectronic devices and circuits.
