The Traveling Wave Tubes (TWT) is a powerful vacuum electronic device used to amplify radio-frequency (RF) signals as well as numerous applications such as radar, television and telephone satellite communications. This monograph is devoted to the author's original theoretical developments in the theory of a traveling wave tube (TWT).Most of the monograph is the author's original work on an analytical theory of TWTs. It is a constructive Lagrangian field theory of TWT in which the electron beam (e-beam) is represented by one-dimensional multi-stream electron flow and the guiding slow-wave structure is represented by possibly non-uniform multi-transmission line (MTL). The proposed analytic theory accounts for a number of electron plasma phenomena including space-charge effects such as electron-to-electron repulsion (debunching), convective instabilities, wave-particle interaction, amplifying waves and more. It allows, in particular, to (i) identify origins of the wave-particle interaction and the system convective instability (exponential growth); (ii) evaluate the energy transfer rate from the e-beam to the electromagnetic radiation; (iii) identify instability modal branches which under condition of sufficiently strong coupling between the e-beam and the MTL can cover ideally all frequencies.","brand":"My Store","offers":[{"title":"Default Title","offer_id":49311184093323,"sku":"P353530220617275475","price":25.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0759\/9190\/8491\/files\/007a9002dd901de0912e68d54234870785673fa8a54b6b33c3b66ac4989e085f.avif?v=1788579092","url":"https:\/\/renala.shop\/products\/pre-owned-an-analytic-theory-of-multi-stream-electron-beams-in-traveling-wave-tubes-hardcover-by-alexander-figotin","provider":"My Store","version":"1.0","type":"link"}
