Beam Profile Monitoring of Synchrotron Radiation by Adaptive Optics

抄録

A beam profile monitoring system for synchrotron radiation, designed to evaluate the distribution of a cross section of the electron beam in a high-energy accelerator storage ring in real-time is descripted. The Shack-Hartmann wavefront sensor is adopted for the measurement of the wavefront error caused by deformation of an extraction beryllium mirror for the visible synchrotron radiation. The correction of the measured wavefront distortion is also described.
