在美国橡树岭国家实验室（National Laboratory）的高能中子源（SNS）的高能中子和压力（SNAP）衍射装置上研制了用于中子衍射实验的金刚石对顶砧（DAC）。在SNAP中，在室温下收集了高达94 GPa的冰VII的中子数据。此外，还可以利用DAC、PE电池和气压电池进行低温中子实验。本文介绍了实验技术，并对冰材料高压中子实验进行了评述。[中子衍射，高压，Spanish中子源，DAC]
The diamond anvil cells (DACs) for the neutron diffraction experiments were developed at the high-pressure diffraction instrument, the Spallation Neutrons and Pressure (SNAP) in the Spallation Neutron Source (SNS), Oak Ridge National Laboratory, USA. In the SNAP, the neutron data of ice VII were collected up to 94 GPa at room temperature. Also, the low temperature neutron experiments can be performed by using the DAC, PE-cell and gas-pressure-cell. In this article, the introduction for experimental techniques and review of the high-pressure neutron experiments on icy materials are shown.
