A Beam-profile Monitor for the Bnl Accelerator Test Facility (atf)
نویسندگان
چکیده
A beam-profile monitor has been designed to diagnose the 5-MeV high-brightness electron beam from the rf gun of the BNL Accelerator Test Facility ‘(ATF). The monitor consists of a phosphor screen viewed by a CCD camera. The video images are digitized and stored by a framegrabber and analyzed by an IBM PC-AT to extract the emittance. Details of the hardware configuration are presented, along with the spatial resolution of the system measured as a function of phosphor-screen thickness. The strategies which will be used to measure the transverse and longitudinal emittances are briefly mentioned. The system should be capable of measuring a transverse geometric emittance of around 1 mm-mrad, as will be typical of the ATF beam.

The performance of single crystal YAG:Ce (Y3Al5O12 ) beam profile monitors was studied for transverse measurements on the high brightness ultrarelativistic electron beam at Accelerator Test Facility (ATF) at BNL. The test demonstrated systematic intensity dependent beam image enlargement on YAG monitors, compare to other diagnostics. Possible mechanisms of the effect have been studied. The quan...
