Phys. Rev. ST Accel. Beams 12, 070703 (2009) [7 pages]Electron beam requirements for Smith-Purcell backward wave oscillator with external focusing
Vinit Kumar1 and Kwang-Je Kim2 Received 20 January 2009; published 24 July 2009 Operation of the Smith-Purcell backward wave oscillator requires a flat electron beam. Without the electron beam focusing, the requirement leads to a very stringent criterion on vertical emittance. In this paper, we discuss a way to relax the criterion by introducing an external focusing. ©2009 The American Physical Society
