描述了用于高压实验的X射线衍射设备的特性。该构造具有便于其使用的模块化结构。三种不同的模式是可能的：（i）使用多色入射光束的能量色散方法;（ii）使用位置敏感检测器的单色方法;（iii）单色扫描方法，使用固定角度的检测器和单色仪扫描通过感兴趣的能量范围。通过使用氮气低温恒温器和金刚石压砧，也可以在135至500 K的温度范围内进行高压工作。在低于135 K的温度下进行高压工作是使用氦低温恒温器进行的。
The properties of the x‐ray diffraction equipment for high‐pressure experiments are described. The construction has a modular structure which facilitates its use. Three different modes are possible: (i) Energy dispersive method using a polychromatic incident beam; (ii) monochromatic method using a position sensitive detector; (iii) monochromatic scan method, using a detector at a fixed angle and a monochromator scan through the energy range of interest. By employing a nitrogen cryostat and a diamond anvil cell, high‐pressure work in the temperature range of 135 up to 500 K can be performed as well. High‐pressure work at temperatures lower than 135 K is made with a Helium cryostat.
