我们研制了一种用于同步辐射X射线衍射实验的叠层雪崩光电二极管（APD）快速探测器。该探测器有四个独立的APD通道，对16.53keV的X射线探测效率达到55%。由于计数系统的死时间小于4 ns，对16.53keV的X射线获得了高达4.5×108计数/秒的输出率。在储存环的多聚束模式下，动态范围大于1010。脉冲高度测量输出速率高达108计数/秒成功地进行了顺序单通道歧视。
We have developed a fast detector using stacked avalanche photodiodes (APDs) for x-ray diffraction experiments with synchrotron radiation. This detector has four independent channels of APDs, and the detector efficiency has reached 55% in all for 16.53 keV x rays. Since the dead time of the counting system is shorter than 4 ns, output rates of up to 4.5×108 counts/s have been obtained for 16.53 keV x rays. The dynamic range is more than 1010 in the multibunch mode of a storage ring. Pulse-height measurements at output rates of up to 108 counts/s were successfully carried out by sequential single-channel discrimination.
