在核加速器上，结合LaBr3(Ce)探测器和基于数字化和离线分析的专用硬件和软件解决方案，进行了以兆赫计数速率进行的高分辨率γ-射线能谱测量。光谱以高达4 MHz的计数速率测量，能量分辨率几乎或没有退化，采用堆积拒绝算法。报告的结果代表着朝着在燃烧的等离子体设备上进行高分辨率γ-射线光谱测量的最终目标迈进了一步。
High resolution γ-ray spectroscopy measurements at MHz counting rates were carried out at nuclear accelerators, combining a LaBr 3(Ce) detector with dedicated hardware and software solutions based on digitization and off-line analysis. Spectra were measured at counting rates up to 4 MHz, with little or no degradation of the energy resolution, adopting a pile up rejection algorithm. The reported results represent a step forward towards the final goal of high resolution γ-ray spectroscopy measurements on a burning plasma device.
