Abstract

This article focuses on optimizing the thermal deformation of liquid-metal-bath cooled horizontally deflecting mirrors used in the Hefei Advanced Light Facility (HALF), a fourth-generation synchrotron radiation facility in China. Using finite element analysis, the study investigates the effects of notch depth (Dnotch) and position (Bnotch) on the mirror's thermal bending and heat bump, aiming to minimize thermal deformation while satisfying mechanical constraints related to mirror fixation. The optimized notch parameters significantly improve the meridian curvature radius and reduce residual slope error, thereby enhancing beam quality across multiple photon energy points. Ray tracing analysis confirms that the optimized cooling scheme effectively maintains the beam's focal spot size, demonstrating the method's potential for improving mirror performance in high-heat load synchrotron beamlines.
