论文摘要
来自核反应堆的抗神经毒素包含一个不可抑制的信号，该信号带有有关核心的信息。掺杂的水基切伦科夫检测器可以检测反应堆抗逆转录杆菌，以进行远场远程反应堆监测非扩散应用。 已经开发了两个新颖的独立重建和分析途径，并应用于许多代表性的反应堆信号，以评估千座尺度的Gadolinium掺杂的Cherenkov检测器作为远程监视器的灵敏度。 评估了位于布尔比矿场（Boulby Mine）的检测器，靠近英国布尔比（Boulby）地下实验室，评估了四个检测器对9个反应堆信号组合的敏感性。发现一个22〜M的检测器，具有高掺杂的，水性液体闪烁体填充物对$ \ rm \ sim 3〜GW_ {th} $反应器敏感，在两年内，在当前的反应器景观中，在$ \ rm \ sim150〜 km $的秒针上处于销售。需要较大的检测器才能实现更及时的检测或监视较小或更遥远的反应器。
Antineutrinos from a nuclear reactor comprise an unshieldable signal which carries information about the core. A gadolinium-doped, water-based Cherenkov detector could detect reactor antineutrinos for mid- to far-field remote reactor monitoring for non-proliferation applications. Two novel and independent reconstruction and analysis pathways have been developed and applied to a number of representative reactor signals to evaluate the sensitivity of a kiloton-scale, gadolinium-doped Cherenkov detector as a remote monitor. The sensitivity of four detector configurations to nine reactor signal combinations was evaluated for a detector situated in Boulby Mine, close to the Boulby Underground Laboratory in the UK. It was found that a 22~m detector with a gadolinium-doped, water-based liquid scintillator fill is sensitive to a $\rm \sim 3~GW_{th}$ reactor at a standoff of $\rm \sim150~km$ within two years in the current reactor landscape. A larger detector would be required to achieve a more timely detection or to monitor smaller or more distant reactors.
