Electron Multi-Beams (Electron Grids, Electron Lattices and Electron Grates): New Elements for Accelerators

Abstract

Since the initial proposal in 1990s, the method of electron lenses has been successfully developed and employed at the high energy particle colliders, like Tevatron and RHIC. Here we propose a new set of electron multi beam elements (electron grids, electron lattices, electron grates and other) which employ many beams in various spatial configurations, with possible time varying currents. We present major principles of operation and generation of such systems and briefly discuss a set of possible applications in accelerators.
