Abstract

Avalanche photodiode detectors (APDs) at X-ray synchrotrons are typically limited to recording at most one photon per synchrotron pulse. Digitizing the APD amplifier outputs enables signal processing to accurately measure a mean count rate of at least four photons per pulse based on initial synchrotron measurements. Higher rates are readily achievable. This method allows APDs to be utilized for time-resolved measurements at much higher intensities than before.

用雪崩光电二极管探测器计算每个脉冲的多重x射线。

x射线同步加速器上的雪崩光电二极管探测器（apd）通常被限制在每个同步加速器脉冲最多记录一个光子。数字化APD放大器输出使信号处理能够准确地测量基于初始同步加速器测量的每脉冲至少四个光子的平均计数率。更高的利率是很容易实现的。这种方法允许apd在比以前高得多的强度下进行时间分辨测量。
