AI Technical Summary

Problems solved by technology

The focal length of the grazing incidence optical lens is large, the distance between the preamplifier assembly and the optical lens is large, and the diameter of the detector is small, and a small deviation of the optical axis of the optical lens will cause a large focus position shift, resulting in a focus spot It cannot be located in the center of the detector, or even deviates from the sensitive area of ​​the detector, and the focusing position of X-rays on the detector surface directly determines the measurement accuracy of photon arrival time, so the distance between the optical axis of the optical lens and the center of the detector must be strictly controlled. coincide
