中文摘要：
对合肥光源中使用的钮扣型束流位置检测器进行了相关参数的计算，计算了水平和垂直方向的灵敏度。对内在分辨率和传输功率进行了估算。用优化后的检测器安装位置参数对束流位置进行了高精度数值仿真，对测量数据用差比和和对数比方法进行处理，得到直观的mapping图和拟合多项式。对束流和信号进行仿真拟合，当束流位移从（0 mm，0 mm）到（4 mm，4 mm）时，归一化和信号的变化小于5×10－3。
英文摘要：
The calculation of relevant parameters of the button beam position monitor （BPM） at Hefei Light Source （HLS） was presented. The horizontal and vertical sensitivity were calculated. The intrinsic resolution and transmission power were calculated under certain parameters. The high precision beam position was simulated with the optimized detector installation location parameters. The measured data were processed by the difference/sum and log-ratio method to obtain the intuitive mapping figure and fitting polynomial. The sum signal was simulated and fitted. The variety range of normalized sum signal was less then 5×10—3 when the beam displacement changed from （0 mm, 0 mm） to （4 mm, 4 mm）.
