It has an ultralow emittance (~50pm.rad) and small beam size, thus the requirement of BPM in precision and resolution is quite high. Independent supports with high degree of mechanical and thermal stability will be employed for some special BPMs, such as the BPMs near the insert devices. The supports should have high eigen-frequencies to minimize the amplification of vibration from the ground. Vibrations information of the ground around the supports also need be estimated, with which FEA (finite element analysis) had be utilized to simulate the performance of the supports. Measurements of vibrational stability of the prototype supports have be done and compared with the simulation.
