我们开发了一个x射线探测器系统，该系统使用64像素硅雪崩光电二极管（Si-APD）线性阵列和用于多通道缩放的快速脉冲计数电子器件。Si-APD线性阵列由64个像素组成，每个像素的尺寸为100 × 200 μ m2，像素间距为150 μ m，损耗深度为10 μ m，由超快专用集成电路和现场可编程门阵列组成的快速电子元件可以以1ns的脉冲对分辨率记录到达线性阵列每个像素的x射线的位置和时间。利用14.4 keV同步加速器x射线在57Fe上进行核共振前向散射实验，测量了计数分布，并通过倾斜探测器提高了空间分辨率。我们还成功地测量了非晶态合金Fe78Si9B13的加热过程。
We developed an X-ray detector system using a 64-pixel silicon avalanche photodiode (Si-APD) linear array and fast pulse-counting electronics for multichannel scaling. The Si-APD linear array consists of 64 pixels each 100 × 200 μ m2 in size, with a pixel pitch of 150 μ m and depletion depth of 10 μ m. The fast electronics, consisting of an ultrafast application-specific integrated circuit and field-programmable gate arrays, can record both the position and timing of X-rays arriving at each pixel of the linear array with 1 ns pulse-pair resolution. The count distribution was measured using 14.4 keV synchrotron X-rays for nuclear resonant forward scattering experiments on 57Fe, and the spatial resolution was improved by inclining the detector. We also successfully measured amorphous alloy Fe78Si9B13 during heating.
