基于时间投影法的新型中子探测器

Novel Neutron Detectors based on the Time Projection Method

M. Köhli, K. Desch, M. Gruber, J. Kaminski, F. P. Schmidt, T. Wagner

摘要:

我们提出了一种新的热中子探测器的第一个原型使用时间投影方法。该系统由8个TimePix ASICS和后处理InGrid网格组成。每个ASIC具有256 × 256像素,尺寸为55 μ m × 55 μ m,能够测量电荷或时间。这允许可视化整个转换粒子轨迹及其空间和时间信息,并通过使用事件重建算法来区分其他粒子的背景。通过使用可扩展的读出系统,这里提出的探测器也可以升级到更大的有源区域。在当前配置中,我们可以实现$σ= (115\pm8)$ μ m的空间分辨率。

英文摘要:

We present the first prototype of a novel thermal neutron detector using the time projection method. The system consists of 8 TimePix ASICS with postprocessed InGrid meshes. Each ASIC has 256 x 256 pixels of 55 mum x 55mum in size with the capability to measure charge or time. This allows to visualize entire conversion particle tracks with their spatial and time information and, by using event reconstruction algorithms, discriminate against the background of others. By using the Scalable Readout System the detector as presented here could also be upscaled to much larger active areas. In the current configuration we could achieve a spatial resolution of $σ= (115\pm8)$ mum.
