摘　　要：为实现试验束束流位置的非拦截测量,研制了3个条形电极束流位置探测器和一批真空定位子。利用高定位精度电控精度电控位移平台对这3个探测器分别进行了标定,随后进行了束流初步试验。探测器主要由位于真空管道内的4条1 mm厚不锈钢条带构成,条带上感应信号的大小反映束流位置的变化。给出了探测器的定标系数、系统特性阻抗和端口传输系数。Three stripline beam position monitors and some feed-throughs were developed to measure the position of beam non-imtereeptively in test beam facility. After three stripline beam position monitors were produced, calibrations of the monitors were carried out on a workbench,which has high precision and is controlled by a computer. Then two monitors were installed at the beam line and some experiments were carried out. Four 1 mm thickness stainless steel strips are main modules of the monitor, signals induced in these strips reflect the position of the beam bunch. Calibration coefficient, system characteristic impedance and port transmission coefficient of monitor are introduced in this paper.
