Book Description
Since propagation characteristics of an electron beam traversing a neutral gas are determined by the response of the beam electrons to their self-fields, an accurate evaluation of the electric and magnetic (EM) fields is essential to any propagation analysis. We report here on theoretical models that were developed for the electromagnetic fields associated with an electron beam propagating in air. One- and two-dimensional models of the fields, and a model for the electron avalanche of the air, were solved on a computer. The major conclusions from calculational results are: the ionization model adequately describes the ionization process over a pressure range of from five Torr to 760 Torr; ionization lag from the high energy secondary electrons is unimportant; in many cases the one-dimensional model was found to be as good as the two-dimensional model; and the net current saturates near 15 kilo-Amperes at sea-level pressure, and saturates at lower values at lower air pressure.

Book Description
This report analyzes Soviet research on the transport of intense relativistic electron beams (IREB) through low-pressure air and other gases without external magnetic fields. It reviews research reported in open-source technical publications from seven Soviet research institutes. These research papers indicate that Soviet interest in long-distance IREB transport at low gas pressure has endured from 1979 to the present.

Book Description
Particle Accelerator Physics covers the dynamics of relativistic particle beams, basics of particle guidance and focusing, lattice design, characteristics of beam transport systems and circular accelerators. Particle-beam optics is treated in the linear approximation including sextupoles to correct for chromatic aberrations. Perturbations to linear beam dynamics are analyzed in detail and correction measures are discussed, while basic lattice design features and building blocks leading to the design of more complicated beam transport systems and circular accelerators are studied. Characteristics of synchrotron radiation and quantum effects due to the statistical emission of photons on particle trajectories are derived and applied to determine particle-beam parameters. The discussions specifically concentrate on relativistic particle beams and the physics of beam optics in beam transport systems and circular accelerators such as synchrotrons and storage rings. This book forms a broad basis for further, more detailed studies of nonlinear beam dynamics and associated accelerator physics problems, discussed in the subsequent volume.
