论文摘要
塑料闪烁体EJ-260的非线性能量响应是用微琴探测器测量的，使用三角大学核实验室的能量5至27 MeV的中子束。第一阶和二阶Birks的常数是从数据中提取的，发现为$ k_b =（8.70 \ pm 0.93）\ times 10^{ - 3} \ {\ rm g/cm^2/mev} $和$ k_c =（1.42 \ pm 1.00） （g/cm^2/mev）^2} $。该结果涵盖了一个独特的能量范围，该能量范围与反应堆逆β衰减探测器中的快速中子背景具有直接相关性。这些测量将改善塑料闪烁体检测器的能量非线性建模。特别是，更新的能量响应模型将基于Chandler反应堆中微子检测器技术的检测器改善快速中子建模。
The non-linear energy response of the plastic scintillator EJ-260 is measured with the MicroCHANDLER detector, using neutron beams of energy 5 to 27 MeV at the Triangle Universities Nuclear Laboratory. The first and second order Birks' constants are extracted from the data, and found to be $k_B = (8.70 \pm 0.93)\times 10^{-3}\ {\rm g/cm^2/MeV}$ and $k_C = (1.42 \pm 1.00) \times 10^{-5}\ {\rm (g/cm^2/MeV)^2}$. This result covers a unique energy range that is of direct relevance for fast neutron backgrounds in reactor inverse beta decay detectors. These measurements will improve the energy non-linearity modeling of plastic scintillator detectors. In particular, the updated energy response model will lead to an improvement of fast neutron modeling for detectors based on the CHANDLER reactor neutrino detector technology.
