Abstract

We report on the commissioning results of the cold neutron multiplexing secondary spectrometer CAMEA (Continuous Angle Multi-Energy Analysis) at the Swiss Spallation Neutron Source at the Paul Scherrer Institut, Switzerland. CAMEA is optimized for efficient data acquisition of scattered neutrons in the horizontal scattering plane, allowing for detailed and rapid mapping of low-energy excitations under extreme sample environment conditions.

摘要

我们报告了在瑞士保罗谢勒研究所的瑞士散裂中子源上的冷中子多路复用次级谱仪 CAMEA（连续角度多能量分析）的调试结果。CAMEA 针对水平散射平面中散射中子的高效数据采集进行了优化，允许在极端样品环境条件下对低能激发进行详细和快速的映射。
