A sample cell for powder X-ray diffraction studies with applied pressure and control of temperature is demonstrated. The cell is based on a previously reported design and consists of a glass or quartz capillary glued into a Swagelok weld gland; this configuration can hold up to 100 bar (1 bar = 100 kPa). The cell is placed in contact with a copper plate for control of temperature between -30 and 200°C. This is achieved by Peltier elements, heat cartridges and a refrigerated circulating bath. This work mainly focuses on the temperature control system. Commissioning tests were performed in a custom-made small/wide-angle X-ray diffractometer at the Norwegian University of Science and Technology. The system is easily portable to synchrotron facilities.
展示了一种用于粉末X射线衍射研究的样品池，该样品池可施加压力并控制温度。该样品池基于先前报道的设计，由一根玻璃或石英毛细管粘接到Swagelok焊接密封套中组成；这种结构能够承受高达100巴（1巴 = 100千帕）的压力。样品池与一块铜板接触，以便在-30至200°C之间控制温度。这是通过珀耳帖元件、加热盒和制冷循环浴来实现的。这项工作主要集中在温度控制系统上。调试测试在挪威科技大学定制的小/广角X射线衍射仪上进行。该系统易于携带到同步加速器设施中。
