摘要:

CAMEA ESS中子谱仪的设计是为了在水平散射面实现高探测效率,并最大限度地利用长脉冲欧洲散射源。它是一种间接几何飞行时间谱仪,使用晶体分析仪来确定从样品散射的中子的最终能量。与其他间接宝石光谱仪不同,CAMEA将使用十个同心弧分析仪来分析十种不同最终能量的散射中子,通过使用棱镜分析可以增加到30种最终能量。在这份报告中,我们将概述CAMEA仪器的概念,大的性能增益,和潜在的科学进步,可以与这种仪器。

英文摘要:

The CAMEA ESS neutron spectrometer is designed to achieve a high detection efficiency in the horizontal scattering plane, and to maximize the use of the long pulse European Spallation Source. It is an indirect geometry time-of-flight spectrometer that uses crystal analysers to determine the final energy of neutrons scattered from the sample. Unlike other indirect gemeotry spectrometers CAMEA will use ten concentric arcs of analysers to analyse scattered neutrons at ten different final energies, which can be increased to 30 final energies by use of prismatic analysis. In this report we will outline the CAMEA instrument concept, the large performance gain, and the potential scientific advancements that can be made with this instrument.
