Book excerpt: The results obtained in the investigation of high current relativistic electron beams produced by explosive electron eMission from the flare cathode plasma of a high voltage, cold-cathode, field-emission diode are reported. In addition, the production of high power (~100kW) microwave radiation through the interaction of such beams with the natural modes of a resonant cavity is reported. A Marx bank generator was used to excite a hollow cylindrical cathode stalk producing diode currents of the order of 1 kA. A fraction (d"5%) of the diode current was transmitted through a thin anode mesh to produce a relativistic electron beam drifting in a low pressure (2 æ torr) region. Diode voltage pulse widths of typically one microsecond were observed with anode-cathode (A-K) gap spacings of 1.5mm to 50mm being employed. The thermal expansion of the cathode plasma resulted in a time dependent diode impedance and measurements of this impedance for varying initial A-K gap settings illustrated a space-charge limited current-voltage characteristic. A quasi-static magnetic field, produced by a pulsed solenoidal coil, was used to magnetise the vacuum drift space in which the beam propagated. The interaction of the relativistic beam with the magnetic field produced high power microwave radiation at X-band and Q-band frequencies. The most prominent feature of this interaction was the existence of sharp "resonant" field values where radiation ocurred. This self-excited radiation is thought to be due to an interaction between the Doppler-shifted electron cyclotron frequency (ECF) of the electron beam and the natural modes of oscillation of the cavity in which the beam drifts. Observation of radiation at Q-band frequencies would indicate that harmonics of the ECF are also present, albeit at weaker intensities. The magnitude of the collected electron beam current was observed to be dependent upon the strength of the applied magnetic field in which the beam drifted.

This book was released on 1987 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soviet research on the propagation of intense relativistic electron beams (IREB) through fairly high-pressure air (pressure range 0.1 to 760 Torr) since the early 1970s has included the study of the plasma channel created by the passage of the electron beam through air, the resistive hose instability and its effect on beam propagation, the effect of self-fields, current enhancement, gas expansion, return currents, inherent beam energy spread, and other factors. This report covers Soviet developments in IREB propagation through air where the beam is not focused by external magnetic fields. The information was obtained from Soviet open-source publications with emphasis given to the last ten years of beam propagation in the Soviet Union. The volume of papers published on this subject in recent years indicates a significant increase in Soviet research in this area.

This book was released on 2003-05-11 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent scientific and technical advances have made it possible to create matter in the laboratory under conditions relevant to astrophysical systems such as supernovae and black holes. These advances will also benefit inertial confinement fusion research and the nation's nuclear weapon's program. The report describes the major research facilities on which such high energy density conditions can be achieved and lists a number of key scientific questions about high energy density physics that can be addressed by this research. Several recommendations are presented that would facilitate the development of a comprehensive strategy for realizing these research opportunities.

This book was released on 1978 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last few years, the application of intense, relativistic- electron beams to the generation of electromagnetic radiation at wavelengths ranging from 10 cm down to fraction of a millimeter has enabled significant advances to be made in peak power capabilities. The purpose of this review is to summarize the status of these advances and to describe briefly the nature of the several mechanisms involved.
