一个X射线束位置监测器（XBPM）的原型，可以在脉冲模式下操作的设计和演示。该监视器具有用于信号传输线的微带线结构和溅射在金刚石热沉上的钛电极作为光电阴极。该监测器的检测元件产生单极单脉冲，其半峰全宽小于1 ns，允许对同步辐射光束进行逐脉冲测量。通过合成这些脉冲，从脉冲到脉冲提供了直接可读的位置敏感信号。该监测器可用于直流模式，在这种模式下，它表现出与传统的XBPM一样好的稳定性和分辨率。文中还介绍了该监测器在SPring-8同步辐射光束线上的性能测试结果。
An x-ray beam position monitor (XBPM) prototype that can be operated in pulse mode has been designed and demonstrated. The monitor has a microstripline structure for signal transmission lines and a titanium electrode sputtered on a diamond heat sink as a photocathode. The detection elements of this monitor generate unipolar single pulses with a full width at half maximum of less than 1 ns, allowing a pulse-by-pulse measurement of the synchrotron radiation beam. By synthesizing these pulses, a directly readable position sensitive signal is provided from pulse to pulse. This monitor can be used in the direct current mode in which it exhibits a stability and resolution as good as those of conventional XBPMs. Results of the performance tests of the monitor at the SPring-8 synchrotron radiation beam line are also presented.
