The beam design is that the emission is less than 100 pm·rad, and the beam instability is less than 10% of the beam spot. Therefore, the revolution of the beam position monitor (BPM) needs to be less than 0.12 ¿m for closed orbit detection. In order to achieve such excellent resolution, the signal-to-noise ratio of the BPM output signal in the 10MHz bandwidth is required to be better than 66dB. After the finite element numerical analysis, the diameter of the pickup electrode will be 8mm, and the gap between the electrode and the vacuum chamber will be 0.3 mm.
