我们研制了一种用于中子散射的高压池。该电池使用由烧结陶瓷制成的桶形支撑圆柱体。可容纳直径6 mm和10 mm长的样品。在室温下产生的压力被锁定后，该电池适合在低温和高温下使用。通过测量NaCl的晶格参数，估算了冷却到低温时压力的变化。除了压力锁定技术外，还可以在室温下使用内置的小型压力机，同时将电池安装在中子谱仪的角度计上，实现连续加压。
We have developed a high-pressure cell for neutron scattering. The cell uses a barrel-shaped support cylinder made of sintered ceramics. Samples 6 mm in diameter and 10 mm long can be accommodated. The cell is suitable for use at low and high temperatures, after a pressure generated at room temperature is locked. The change of pressure on cooling to cryogenic temperatures is estimated by measuring the lattice parameter of NaCl. Besides the pressure locking technique, continuous pressurization can be achieved at room temperature by using a built-in mini-press while the cell is mounted on a goniometer of neutron spectrometer.
