Development of a Laser Wire Beam Profile Monitor

Abstract

Production or mamipulation of a low emittance electron beam will become an indispensable technique to realize a thirdgeneration synchrotron source, X-ray region free-electron laser and TeV-scale linear collider in the future. It is thus essential to have a good "eye" a reliable monitor to measure its emittance. We report in this article the development of a laser wire beam profile monitor, including its principle, salient features and actual measurement procedures.
