PLANET是一条专门用于高压和高温实验的时间（ToF）中子束线。专为ToF中子衍射实验设计的大型六轴多砧高压压机可以在高达10 GPa和2000 K的高压和高温下进行常规数据收集。为了获得干净的数据，光束线配备了入射狭缝和接收准直器，以消除来自高压单元组件的寄生散射。衍射仪的高性能分辨率（Δ d/d接近0.6%）和可访问的d间距范围（0.2-8.4埃）以及低寄生散射特性使得能够在高压和高温条件下精确测定晶体和液体的结构。(C)2015 Elsevier B. V.版权所有。
PLANET is a time (ToF) neutron beamline dedicated to high-pressure and high temperature experiments. The large six axis multi anvil high-pressure press designed for ToF neutron diffraction experiments enables routine data collection at high pressures and high temperatures up to 10 GPa and 2000 K, respectively. To obtain clean data, the beamline is equipped with the incident slits and receiving collimators to eliminate parasitic scattering from the high-pressure cell assembly. The high performance of the diffractometer for the resolution (Delta d/d similar to 0.6%) and the accessible d-spacing range (0.2-8.4 angstrom) together with low parasitic scattering characteristics enables precise structure determination of crystals and liquids under high pressure and temperature conditions.
