论文摘要
我们在具有CD $ _2 $纳米线目标的激光等离子体实验中介绍了中子检测的结果。覆盖中子转换器覆盖的混合半导体像素探测器TimePix3用于检测中子。通过后退质子在聚乙烯转化器中检测到D-D融合中子。确定了后退质子的能量和中子的飞行时间（及其能量）。我们报告了$（2.4 \ pm 1.8）\ times 10^7 $中子，该中子为1〜J的传入激光能量产生。此外，我们证明了TimePix3适用于激光实验中的困难操作条件。
We present the results of neutron detection in a laser plasma experiment with a CD$_2$ nanowire target. A hybrid semiconductor pixel detector Timepix3 covered with neutron converters was used for the detection of neutrons. D-D fusion neutrons were detected in a polyethylene converter through recoiled protons. Both the energy of recoiled protons and the time-of-flight of neutrons (and thus their energy) were determined. We report $(2.4 \pm 1.8) \times 10^7$ neutrons generated for 1~J of incoming laser energy. Furthermore, we proved that Timepix3 is suitable for difficult operational conditions in laser experiments.
