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.

同步辐射束线的脉冲模式X射线束位置监控器原型

设计并演示了可以在脉冲模式下运行的X射线束位置监控器（XBPM）原型。该监视器具有用于信号传输线的微带线结构，以及溅射在金刚石散热片上的钛电极作为光电阴极。该监视器的检测元件产生单极性单脉冲，其半峰全宽小于1 ns，从而可以对同步加速器辐射束进行逐脉冲测量。通过合成这些脉冲，可以在各个脉冲之间提供直接可读的位置敏感信号。该监视器可以在直流模式下使用，在该模式下它具有与传统XBPM一样的稳定性和分辨率。还介绍了在SPring-8同步加速器辐射束线上进行的显示器性能测试的结果。
