This book provides a comprehensive overview of the operating principles and technology of
electron lenses in supercolliders. Electron lenses are a novel instrument for high energy
particle accelerators particularly for the energy-frontier superconducting hadron colliders
including the Tevatron RHIC LHC and future very large hadron colliders. After reviewing the
issues surrounding beam dynamics in supercolliders the book offers an introduction to the
electron lens method and its application. Further chapters describe the technology behind the
electron lenses which have recently been proposed built and employed for compensation of
beam-beam effects and for collimation of high-energy high-intensity beams for compensation of
space-charge effects and several other applications in accelerators. The book will be an
invaluable resource for those involved in the design construction and operation of the next
generation of hadron colliders.
