在过去的25年里，利用冷的极地冰作为中微子目标，对中微子产生的信号进行无线电波探测，可能是探测河外超高能中微子（对应于中微子能量超过0.01焦耳或1017电子伏）的最有前途的技术。在2021年夏季，随着格陵兰射电中微子天文台（RNO-G）的初步部署，我们在格陵兰Summit Station进行了射电冰川测量，以完善我们对冰目标的理解。我们报告了一个这样的测量结果，频率为ν ∈ [145 − 350] MHz的射频电场衰减长度。
Over the last 25 years, radiowave detection of neutrino-generated signals, using cold polar ice as the neutrino target, has emerged as perhaps the most promising technique for detection of extragalactic ultra-high energy neutrinos (corresponding to neutrino energies in excess of 0.01 Joules, or 1017 electron volts). During the summer of 2021 and in tandem with the initial deployment of the Radio Neutrino Observatory in Greenland (RNO-G), we conducted radioglaciological measurements at Summit Station, Greenland to refine our understanding of the ice target. We report the result of one such measurement, the radio-frequency electric field attenuation length for frequencies ν ∈ [145 − 350] MHz.
