Topics in applied physics ;Volume 1353-030-47290-6 Includes bibliographical references and index.Historical development and advanced new applications of vacuum electron sources -- State of the art and future perspectives of Scandate cathodes -- Review of impregnated and reservoir Ba dispenser cathodes -- New developments in Ba oxide cathodes -- Electron sources for medical X-ray tubes -- High brightness cathodes for high resolution electron beam applications -- Progress in field electron emission science -- Carbon-based field emitters, properties and applications -- Explosive electron emission of carbon based cathodes and applications -- Photocathodes.This book gives an overview of modern cathodes and electron emitters for vacuum tubes and vacuum electron devices in general. It covers the latest developments in field emission theory as well as new methods towards improving thermionic and cold cathodes. It addresses thermionic cathodes, such as oxide cathodes, impregnated and scandate cathodes, as well as photocathodes and field emitters – the latter comprising carbon nanotubes, graphene and Spindt-type emitter arrays. Despite the rise and fall of the once dominant types of vacuum tubes, such as radio valves and cathode ray tubes, cathodes are continually being improved upon as new applications with increased demands arise, for example in electron beam lithography, high-power and high-frequency microwave tubes, terahertz imaging and electron sources for accelerators. Written by 17 experts in the field, the book presents the latest developments in cathodes needed for these applications, discussing the state of the art and addressing future trends.Topics in applied physics ;Volume 135.Vacuum microelectronicsField emissionVacuum microelectronics.Field emission.621.381Gaertner GeorgKnapp Walter H.Forbes R(Richard),MiAaPQMiAaPQMiAaPQBOOK996418436003316Modern Developments in Vacuum Electron Sources1882009UNISA02341oam 2200541I 450 991097198890332120240401171330.01-04-021272-70-429-16833-01-4665-8807-110.1201/b16296 (CKB)2670000000395027(EBL)1378847(SSID)ssj0001080805(PQKBManifestationID)11719419(PQKBTitleCode)TC0001080805(PQKBWorkID)11070918(PQKB)11100413(MiAaPQ)EBC1378847(OCoLC)865579118(EXLCZ)99267000000039502720180331h20142014 uy 0engur|n|---|||||txtccrImproper Riemann integrals /Ioannis M.

The book gives students the prerequisites and tools to understand the convergence, principal value, and evaluation of the improper/generalized Riemann integral. It also illustrates applications to science and engineering problems.The book contains the necessary background, theorems, and tools, along with two lists of the most important integrals and sums computed in the text.
