We describe a unique cryogen-free closed-cycle refrigerator system using a beryllium-copper VX1 variant of the Paris-Edinburgh press, which enables approximately 3 GPa to be generated on a sample volume of 66 mm3, over the temperature range of 4 K-300 K. The main advantage of this system is its versatility; it has been designed to be fully compatible with the PEARL neutron powder-diffraction instrument at the ISIS facility, but is also compatible with several other instruments at the facility with minor modifications. We provide a full description of the system, along with representative data collected on PEARL from MnF2 at 13 K and 2.4 GPa.

在 4 K 和高压下进行中子衍射的简单系统

我们描述了一种独特的无制冷剂闭式循环制冷系统，该系统使用巴黎-爱丁堡压机的铍铜 VX1 变体，在 4 K-的温度范围内，在 66 mm3 的样品体积上产生大约 3 GPa 300 K。这个系统的主要优点是它的多功能性；它被设计为与 ISIS 设施的 PEARL 中子粉末衍射仪器完全兼容，但也与该设施的其他几台仪器兼容，只需稍作修改。我们提供了该系统的完整描述，以及在 13 K 和 2.4 GPa 下从 MnF2 在 PEARL 上收集的代表性数据。
