新安装的、经过大幅改进的单晶衍射仪，ISIS的SXD，于2001年5月收到了第一批中子。探测器区域现在以立体角度覆盖略多于2RE的立体立体。使用单晶的高压研究正在成为用户方案中日益重要的部分，因此，正在努力提供新的样品环境和最先进的数据分析软件，以在高压单晶衍射中开辟新的机会。最近，一个新的压力高达0.5 Gpa的气体压力室成功地投入使用。首先给出了一系列含有短氢键的分子化合物的结果。ISIS的最新发展包括一种压力高达8 GPA的蓝宝石压腔，该压腔已在宝石粉末衍射仪上成功测试。不久，它还将在SXD和一个改装的巴黎-爱丁堡池上进行测试，以将5-15mm3的单晶样品置于超过10Gpa的压力下。
The newly installed, much-improved single-crystal diffractometer, SXD at ISIS, received its first neutrons in May 2001. The detector area now covers slightly more than 2re steradians in solid angle. High-pressure research using single crystals is becoming an increasingly important part of the user programme and thus, efforts are underway to provide a new sample environment as well as state-of-the-art data analysis software to open new opportunities in high-pressure single-crystal diffraction. Recently, a new gas-pressure cell with pressures up to 0.5 GPa has been successfully commissioned. First results from a series of molecular compounds containing short hydrogen bonds are presented. More recent developments at ISIS include a sapphire anvil cell for pressures up to 8 GPa, which has been successfully tested on the GEM powder diffractometer. It will shortly also be tested on SXD, as well as a modified Paris-Edinburgh cell to take 5-l5mm3 single-crystal samples to pressures of more than lOGPa.
