AI 中文总结

本研究通过NuMI标定的OOK/CRC模拟和理想化远场模型,评估中微子直接通信的可行性,分别给出65.7%正确接受率和24.4兆瓦峰值功率,但未确立实用方案。

AI 中文摘要

中微子能够穿透大量物质,从而可能实现电磁路径受阻时的直接通信链路,但其弱相互作用使得接收变得困难。我们提出了两项独立的计算。第一项是重复的OOK/CRC模拟,该模拟以已发表的NuMI-MINERvA选定事件均值为标定,在五次重复后,对于40位有效载荷和八位CRC,正确接受65.7%的模拟数据包,在假设外部同步的情况下,平均延迟约为587秒。将输入均值在其近似泊松计数区间内变化,正确接受率为60-72%;这是一个灵敏度范围,而非联合置信区间。第二项是独立的理想化远场模型,在5000公里处,对于10千吨接收器,在3 GeV中微子、1毫弧度发散角、50%选择效率、单位味存活率、零背景和一秒时隙的条件下,峰值中微子携带的槽内功率为24.4兆瓦。两项结果均未确立实用的长基线源或实测的CRC性能。

英文摘要

Neutrinos can pass through substantial matter, potentially enabling direct links where electromagnetic paths are obstructed, but their weak interactions make reception difficult. We present two separate calculations. First, a repeated OOK/CRC simulation calibrated to the published NuMI-MINERvA selected-event mean correctly accepts 65.7% of simulated packets with a 40-bit payload and an eight-bit CRC after five repetitions, with about 587 s mean latency under assumed external synchronization. Varying the input mean across its approximate Poisson counting interval gives 60-72% correct acceptance; this is a sensitivity range, not a joint confidence interval. Second, a distinct idealized far-field model gives 24.4 MW peak neutrino-carried on-slot power for a 10 kt receiver at 5,000 km, conditional on 3 GeV neutrinos, 1 mrad divergence, 50% selection efficiency, unit flavor survival, zero background and one-second slots. Neither result establishes a practical long-baseline source or measured CRC performance.
