摘要
轨道稳定性是同步辐射光源一个极其重要的性能指标,稳定的同步辐射光束直接决定着同步辐射实验结果的优劣;对于高稳定性高精度的同步辐射光源用户而言,测量并稳定光源点束流的位置漂移和角度变化尤为重要。测量同步光的位置,主要依靠前端同步光位置检测器的研制,以及后端同步光位置信号处理器的开发;而稳定同步光的位置,则依赖于同步光位置反馈系统的研究。本论文参考国外光源的先进技术,对合肥光源同步光位置测量和稳定技术中的关键技术进行了研究:精确测量同步光的位置,进一步稳定特定光源点同步光的位置和角度,提高光的品质。
     常用于弯铁光束线进行同步光位置测量的二刀片型同步光位置检测器、二分割三角型同步光位置检测器和双丝型同步光位置检测器都只能进行垂直方向的同步光位置测量,无法同时进行水平和垂直两个方向的同步光位置测量,为此我们购置了中电集团44所的InGaAs型探测器产品四象限光位置检测器,并将其应用在合肥光源机器研究光束线PSD支线末端,实验结果表明四象限光位置检测器的灵敏度和线性范围均较好,并且可以同时对水平和垂直两个方向的同步光位置进行长时间精确稳定的测量。
     常用的二刀片型同步光位置检测器、二分割三角型同步光位置检测器和双丝型同步光位置检测器的灵敏度受狭缝变化的影响很大(即受同步光尺寸变化的影响很大),参考国外光源的先进技术,我们在国内首次进行了交错刀片型同步光位置检测器的研制,并提出了比值和对数比两种新的计算方法应用于交错刀片型同步光位置检测器光电流信号的处理。理论模拟和分析的结果表明,交错刀片型同步光位置检测器的灵敏度只跟它的结构参数有关,基本可以忽略同步光尺寸对于其灵敏度的影响。
     合肥光源现有的两套同步光位置测量系统:基于VXI总线的同步光位置测量系统,仅支持差比和算法,且线性范围较小;自制的对数比同步光位置测量系统,仅支持两路光电流信号的输入。两套系统均不能满足新研制交错刀片型同步光位置检测器的数据处理要求。为此我们引进了斯洛文尼亚IT公司开发的成熟商业化数字信号处理器Libera Photon,并在合肥光源进行了应用研究,其可以有效地支持多路输入信号进行差比和以及对数比的运算,全面提升系统的性能。
     合肥光源现有储存环束流轨道慢反馈系统,仅对于全环24个束流位置检测器处的束流位置进行反馈校正,对于光源点的同步光位置和角度,则无法进行校正。虽然进行了基于单个同步光位置检测器的同步光位置慢反馈控制系统的研究调试,但其校正的是该同步光位置检测器处的同步光位置,对于光束线其他位置的同步光位置校正效果不佳,同时也没有实现实时的反馈。因此我们研制了可以进行实时反馈的基于两个同步光位置检测器的同步光位置慢反馈系统,反馈效果良好。
     最后,论文对合肥光源新的同步光位置测量、反馈技术进行了总结,并对下一步研究方向提出了相应的建议。

The beam orbit stability is a very important performance index of the synchrotron radiation light source. The stability of the synchrotron radiation beam directly determines the quality of the experimental results. For the users who require the light source with high stability and high-precision, it is very important to measure and stabilize the beam position and angle of the light source. Measuring the position of photon beam mainly relies on the development of Photon Beam Position Monitor(PBPM) and the signal processor for photon beam position. And stabilization of the position of the photon beam depends on the study of the feedback system. In this thesis, the author will study the key technologies of measuring and stabilizing photon beam position for Hefei Light Source(HLS), with the help of the advanced technologies in foreign countries. To be more specific, the aim is to measure the position of photon beam more precision, and to further stabilize the position and angle of specific light source, in order to improve the quality of photon beam.
     The double blade PBPM, double wire PBPM and the split PBPM usually used in bending beamline can only measure the vertical position of photon beam, but cannot measure the position of photon beam from the horizontal and vertical direction at the same time. So we introduced the four-quadrant PBPM, the product of CETC44, and applied it in machine diagnostic beamline(MDBL) at HLS. The experimental results show that the four-quadrant PBPM is able to measure the position of photon beam from both the horizontal and vertical directions for a long time with great precision and stability.
     The sensitivity of the double blade PBPM, double wire PBPM and the split PBPM we usually used is greatly affected by the changes of the slit (or the size of photon beam). With the help of the advanced technology in foreign countries, we develop the staggered blade-type PBPM for the first time in China, and propose the application of two new calculation methods, ratio and logarithm ratio, to the signal processing of the staggered blade-type PBPM. The results of theoretical simulation and analysis show that the sensitivity of the staggered blade-type PBPM only relates to its structural parameters and the dimensional changes of the photon beam can be ignored.
     The HLS has two sets of PBPM system. One is based on VXI Bus PBPM system, which only supports the A/E method and is with a smaller linear range. The other is the homemade log-ratio PBPM system, which only supports two photocurrent signal inputs. Both systems cannot meet the data processing requirements of the newly developed staggered blade-type PBPM. Therefore, we have introduced Libera Photon, a mature commercialized digital signal processor made by IT company in Slovenia, and conduct a study on its application at HLS. It can effectively support multi-channel inputs of photocurrent signal with Log-ratio calculation, and improve the overall performance of the system.
     The slow feedback system of the storage ring beam orbit at HLS only can feedback and correct the beam position of the ring's24Beam Position Monitor(BPM), and cannot correct the position and angle of light sources. Although HLS had developed a photon beam position feedback system based on one PBPM, but this system only can feedback the position of the PBPM, the effect is poor for the other positions in the beamline, and this system cannot realize real-time feedback. In order to stabilize the position and angle of particular light source, we develop a new photon beam position feedback system based on two PBPMs, which also can realize real-time feedback. It is workable and effective.
     Finally, the thesis summarise the key technologies of photon beam position measurement, and provid some advises for the future work.
