ABSTRACT The principal method used today for single crystal X-ray data collection is the Arndt–Wonacott screenless rotation method formalized in the late 1970s, but the physical hardware used now would be barely recognizable to scientists at that time. However, the technique of rotating a crystal around a single goniostat axis, illuminating it with monochromatic radiation, and collecting the data on a flat detector is identical. Indeed, this would not have been very surprising to the pioneers of X-ray crystallography early in the Twentieth Century, since the elements of this method were available in the early days of the science. In a sense, therefore, we have come full circle after utilizing a variety of different experimental methods and equipment, and the question arises; ‘how did we get here?’; after all, there were long periods in our science where we used point detectors or curved area detectors, or using polychromatic X-rays and stationary crystals. This review was originally presented at ECM31 in Oviedo, Spain in August 2018 under the title `Vagando entre los picos ¿cómo llegué hastaaquí? Improving methods in data collection and processing’; the Spanish texttranslates as ‘Wandering amongst the peaks – how did I get here?’.

从那时到现在：自 1912 年以来单晶 X 射线晶体学数据收集方法的改变

摘要今天用于单晶 X 射线数据收集的主要方法是 1970 年代后期正式确定的 Arndt-Wonacott 无屏旋转方法，但当时使用的物理硬件对当时的科学家来说几乎无法识别。然而，围绕单个测角器轴旋转晶体、用单色辐射照射它以及在平面探测器上收集数据的技术是相同的。事实上，这对于 20 世纪早期 X 射线晶体学的先驱们来说并不令人惊讶，因为这种方法的元素在科学的早期就可用了。因此，从某种意义上说，我们在使用了各种不同的实验方法和设备之后，又回到了原点，问题就来了；'我们是怎么来到这里的？'; 毕竟，在我们的科学中有很长一段时间我们使用点探测器或曲面探测器，或者使用多色 X 射线和固定晶体。该评论最初于 2018 年 8 月在西班牙奥维耶多的 ECM31 上以“Vagando entre los picos ¿cómo llegué hastaaquí? 改进数据收集和处理方法”；西班牙语文本翻译为“在山峰间徘徊——我是怎么到这里的？”。
