Abstract. At HERA a proton synchrotron radiation beam emittance monitor has been installed which utilizes the radiation produced in the fringe field of a vertical deflecting dipole magnet. The beam spot is imaged onto the chip of a standard CCD camera by means of a concave mirror. An interference filter together with a polarization filter serve for resolution improvements. While the monitor was used for the first time in standard operational mode during the previous HERA run period, the set-up was improved in the last shut-down. With start of the new run period the monitor is in a stage of re-comissioning and the first results are presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
