Design study of beam profile monitor of storage ring by using synchrotron radiation

Abstract

The electron beam profile is one of the most important parameters of a storage ring accelerator. This paper presented the design study of one type of beam profile monitor by using synchrotron radiation which was emitted by the electron beam. The beam profile monitor system needs an optical system to image the synchrotron light onto a high resolution image sensor, The system is intended for monitoring 100 mm beam size. Therefore, the aberrations of the system has been studied. Those include the calculation and the reduction of monochromatic and chromatic aberrations. The experimental setup for measuring those aberrations in order to calibrate the results of the beam measurement are presented. We also discussed the synchrotron radiation power consideration for choosing a suitable image sensor. >
