| The stability of beam orbit is absolutely the key performance indexes of a modern synchrotron radiation light source, which affects the performance of accelerator and the quality and stability of synchronous light in experimental line station directly. As a fourth generation synchrotron radiation light source, High Energy Photon Source (HEPS) has characteristics of high energy and low emissivity, which requires very high stability of beam orbit. Beam position monitor (BPM) is an precise instrument used for measuring beam position and orbit, and its mechanical vibration amplitude must less than 100 nm.Therefore, a independent support need to be distinctively designed. Based on the thermal stability and vibration stability, an ultra stability structure of rigid support is designed and optimized. Through the finite element modal analysis of ANSYS, the thermal expansion variation and the characteristic frequency of the support is verified. | ||
