中国绵阳研究堆高压中子衍射谱仪在材料研究中的应用
Application of the High-Pressure Neutron Diffractometer at CMRR in Materials Research
摘要
Abstract
High pressure neutron diffractometer(HPND),also known as FENGHUANG,at China Mianyang Research Reactor's(CMRR)neutron science platform,which include neutron focusing system,detector system,high-pressure devices and integrated system,can be constructed to in situ neutron diffraction experiments under ambient,high/low temperature,and high-pressure conditions.For in situ high-pressure neutron diffraction experiments,the pressure can reach to over 30 GPa at room temperature,and 10 GPa at 2000 K.FENGHUANG diffractometer has been widely applied in the field of materials researches,to provide precise information on atomic occupation,magnetic structure,crystalline structure and phase transitions,such as transition-metal nitrides,Li-containing materials,magnetic materials,energetic materials,ferroelectric ceramics.关键词
