论文摘要
多叶片是一种基于硼10的中子探测器，专为中子反射仪设计，并为瑞典欧洲散布源计划的两种仪器（Estia和Freia）开发。在保罗·施雷尔学院（PSI -Switzerland）的Amor反射计安装了反射仪演示器。该设置利用了Selene指南概念，可以将其视为ESTIA的缩放示威者。讨论了这些测试的结果。它将显示多叶片检测器的特性是允许聚焦反射量学操作模式的功能。此外，就速率能力而言，多型的性能超过了当前的最新技术。关于先前原型的改进也得到了强调。从背景考虑到检测器的线性和角度均匀响应。
The Multi-Blade is a Boron-10-based neutron detector designed for neutron reflectometers and developed for the two instruments (Estia and FREIA) planned for the European Spallation Source in Sweden. A reflectometry demonstrator has been installed at the AMOR reflectometer at the Paul Scherrer Institut (PSI - Switzerland). The setup exploits the Selene guide concept and it can be considered a scaled-down demonstrator of Estia. The results of these tests are discussed. It will be shown how the characteristics of the Multi-Blade detector are features that allow the focusing reflectometry operation mode. Additionally the performance of the Multi-Blade, in terms of rate capability, exceeds current state-of-the-art technology. The improvements with respect to the previous prototypes are also highlighted; from background considerations to the linear and angular uniformity response of the detector.
