在传统的实验室XAFS装置中，使用传统的X射线源，密封管或旋转阳极，已被使用。其中X射线源是固定的，样品是移动的（平移和旋转）。因此，很难或需要复杂的方法来将重元件放置在样品位置处，例如低温冷却器、高温炉和原位反应池。如今，人们对获取样品的动态信息有着强烈的需求，现场观测几乎成为不可避免的。我们研制了一种紧凑型X射线管和一种新的测角仪，其中X射线源在测角仪上移动，单色X射线从测角仪出来。因此，将各种细胞放置在样品位置变得更容易。
In a conventional in-laboratory XAFS apparatus using conventional X-ray source, sealed tube or rotating anode, has been used. In which the X-ray source is fixed and the sample is moved (translated and rotated). Hence it has been difficult or required a complex method in order to put a heavy element, such as a cryogenic cooler, high temperature furnace and an in-situ reacting cell, at a sample position. Nowadays, there is a strong demand for obtaining dynamic information of a sample and in-situ observation becomes almost unavoidable. We have developed a compact X-ray tube and a new goniometer on which X-ray source is moved and monochromatic X-ray comes out of goniometer is fixed. Therefore it becomes easier to put a various cell at a sample position.
