改进了能够对同步辐射装置的同步辐射束线进行逐脉冲位置测量的脉冲式X射线束位置监视器，并进行了评估试验。该监视器配备了刀片形检测元件，利用金刚石散热器来减少杂散电容，并采用微带传输线来改善高频特性。检测元件作为光电阴极运行，并生成半峰全宽小于 1 ns 的单个单极脉冲。该操作允许同步加速器辐射束的逐脉冲测量。为了确保同步加速器辐射功率非常强的SPring-8波荡器光束线的运行，对检测元件进行了进一步改进，以增强耐热性。本文讨论了逐脉冲光子测量和光束注入期间光束振荡观察的灵敏度和分辨率的评估结果。
A pulse-mode X-ray beam position monitor that enables pulse-by-pulse position measurement in the synchrotron radiation beamline of the synchrotron radiation facility was improved, and evaluation tests were performed. The monitor was equipped with blade-shaped detection elements utilizing diamond heatsinks to reduce stray capacitance, and a microstrip transmission line to improve high-frequency characteristics. The detection elements operate as photocathodes and generate single unipolar pulses with a full width at a half-maximum of less than 1 ns. This operation allows pulse-by-pulse measurement of the synchrotron radiation beam. To ensure operations at the undulator beamline in SPring-8, where the synchrotron radiation power is very intense, further improvements were introduced to the detecting elements to enhance heat resistance. The evaluation results of sensitivity and resolution in the pulse-by-pulse photon measurement and observation of beam oscillation during beam injection are discussed herein.
