我们之前成功构建并演示了基于超导电流偏置动感电感探测器(CB-KID)的中子成像系统的功能。在本工作中,我们系统地研究了超导中子探测器的特性,以提高空间分辨率和探测效率。我们发现,当探测器温度从 4 K 升高到临界温度 T c 时,CB-KID 的中子探测事件数量显着增加。我们观察到中子信号随探测器温度从 4 K 到 T c 的变化而变化。我们评估了 CB-KID 探测器的探测效率,并与 PHITS 蒙特卡罗模拟进行了比较,该模拟模拟了 10 B (n, α) 7 Li 反应的连续物理过程、输运动力学以及包括中子、4 He 粒子、7 Li 粒子、光子和电子在内的粒子的能量沉积。
We previously succeeded in constructing and demonstrating the capability of a neutron imaging system based on a superconducting current-biased kinetic inductance detector (CB-KID). In the present work, we systematically studied the characteristics of the superconducting neutron detector to improve the spatial resolution and detection efficiency. We found that the number of neutron detection events with CB-KID remarkably increased when the detector temperature increased from 4 K to the critical temperature T c. We observed systematic changes of neutron signals as a function of the detector temperature from 4 K to T c. We evaluated the detection efficiency of the CB-KID detector, and compared with PHITS Monte Carlo simulations, which modeled the sequential physical processes for the 10 B (n, α) 7 Li reaction, the transport dynamics, and the energy deposition by particles including neutrons, 4 He particles, 7 Li particles, photons, and electrons.
