Penfold and published by . This book was released on 1967 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various discharges which occur surrounding a shielded solenoidal coil excited with current at 4 megacycles are examined for the gases helium, nitrogen, neon, argon, krypton, and xenon in the pressure range 0.02 to 0.50 Torr. Measurements are made of various electrical properties including the operating power and the resistance and inductance reflected into the driving circuit by the discharges. A limited amount of optical spectrographic data was obtained. Microwave measurements were also made for selected conditions. A total of twelve modes of operation of the discharges were observed including Bright and Dim modes. Discharges occur both inside the solenoidal coil and in the space surrounding it. The two types appear to be independent in the sense that they can occur alone or in concert. Various types of fine structure were observed including rings of highly luminous balls of plasma located around the outside of the coil. Power levels up to 4000 watts were used. The values of reflected resistance behave in a manner inconsistent with the observed changes of inductance when correlated through the medium of theory. The values of resistance exhibit only slight dependence on pressure and current except near threshold of the various modes. The maximum change in resistance with type of gas was a factor of two.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on a cutting-edge area of research, which is aligned with CERN's mainstream research, the "AWAKE" project, dedicated to proving the capability of accelerating particles to the energy frontier by the high energy proton beam. The author participated in this project and has advanced the plasma wakefield theory and modelling significantly, especially concerning future plasma acceleration based collider design. The thesis addresses electron beam acceleration to high energy whilst preserving its high quality driven by a single short proton bunch in hollow plasma. It also demonstrates stable deceleration of multiple proton bunches in a nonlinear regime with strong resonant wakefield excitation in hollow plasma, and generation of high energy and high quality electron or positron bunches. Further work includes the assessment of transverse instabilities induced by misaligned beams in hollow plasma and enhancement of the wakefield amplitude driven by a self-modulated long proton bunch with a tapered plasma. This work has major potential to impact the next generation of linear colliders and also in the long-term may help develop compact accelerators for use in industrial and medical facilities.

This book was released on 2017-02-20 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its invention in the 1920s, particle accelerators have made tremendous progress in accelerator science, technology and applications. However, the fundamental acceleration principle, namely, to apply an external radiofrequency (RF) electric field to accelerate charged particles, remains unchanged. As this method (either room temperature RF or superconducting RF) is approaching its intrinsic limitation in acceleration gradient (measured in MeV/m), it becomes apparent that new methods with much higher acceleration gradient (measured in GeV/m) must be found for future very high energy accelerators as well as future compact (table-top or room-size) accelerators. This volume introduces a number of advanced accelerator concepts (AAC) — their principles, technologies and potential applications. For the time being, none of them stands out as a definitive direction in which to go. But these novel ideas are in hot pursuit and look promising. Furthermore, some AAC requires a high power laser system. This has the implication of bringing two different communities — accelerator and laser — to join forces and work together. It will have profound impact on the future of our field.Also included are two special articles, one on 'Particle Accelerators in China' which gives a comprehensive overview of the rapidly growing accelerator community in China. The other features the person-of-the-issue who was well-known nuclear physicist Jerome Lewis Duggan, a pioneer and founder of a huge community of industrial and medical accelerators in the US.

Available in PDF, EPUB and Kindle. Book excerpt: Theoretical studies of plasma acceleration by an rf field gradient indicated that a plasma will be accelerated toward the low-field region if the applied frequency is greater than the critical frequency of the plasma, and toward the high-field region if the frequency is less than the critical frequency. Calculations for the acceleration of plasma spheres and ellipsoids of arbitrary orientation with respect to the rf field have been completed. Experiments with plasmas of various densities have demonstrated both the acceleration and deceleration of the plasmas as predicted by theory. Mercury plasma has been accelerated with a 140-Mc rf field gradient to a velocity of 25 x 100,000 cm/sec, equivalent to a specific impulse of 2500 seconds. (Author).

Download or read book Interaction of Electromagnetic Waves and Electron Beams with Plasmas written by D. N. Gupta and published by LAP Lambert Academic Publishing. This book was released on 2012-03 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the advent of laser and maser, the wave-plasma interaction emerged as a major rich field of research. To explore the possibility of laser driven fusion, laser-plasma interaction became a subject of worldwide research, revealing many novel nonlinear phenomena including generation and saturation of plasma instabilities, electron acceleration, and ion Coulomb explosion. The work presented in this thesis is related to intense laser-plasma and electron beam-plasma interaction. The development of intense short pulse laser and high current, high-energy electron beams has allowed exploration of new regimes of laser and beam plasma interaction. Enormous progress has been made in inertial confinement fusion, plasma heating, X-ray lasers, free electron laser and charged particle accelerators. In these applications parametric instabilities, self-focusing, self phase modulation and other non-linear phenomena are important. The present thesis deals with these phenomena. This work is relevant to laser-driven fusion, charged particle acceleration, and laboratory plasma heating.

This book was released on 1994 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interaction of electromagnetic waves with matter has always been a fascinating subject of study. As matter in the universe is mostly in the plasma state, the study of electromagnetic waves in plasmas is of importance to astrophysics, space physics and ionospheric physics. The physics of electromagnetic wave interacting with electron beams and plasmas also serves as a basis for coherent radiation generation such as free electron laser and gyrotron and advanced accelerators. This monograph aims at reviewing the physical processes of linear and nonlinear collective interactions of electromagnetic waves with electron beams and unmagnetized plasmas.
