用于月球切伦科夫技术的月球成像和电离层定标

Lunar Imaging and Ionospheric Calibration for the Lunar Cherenkov Technique

Rebecca McFadden, Olaf Scholten, Maaijke Mevius

摘要:

月球切伦科夫技术是UHE中微子和宇宙线探测的一种很有前途的方法,其目的是探测月球风化层中粒子相互作用过程中产生的纳秒无线电脉冲。对于低频实验,如NuMoon,电离层的频率相关色散效应是一个重要的实验问题,因为它降低了脉冲幅度和随后的检测机会。我们正在继续研究一种新的方法,通过法拉第旋转测量月球的极化发射结合地磁场模型来校准电离层对月球切伦科夫脉冲的色散效应。我们还将这项工作扩展到包括月球表面的无线电成像,它提供了月球表面的物理和化学性质的信息,可能会影响月球切伦科夫技术的实验策略。

英文摘要:

The Lunar Cherenkov technique is a promising method for UHE neutrino and cosmic ray detection which aims to detect nanosecond radio pulses produced during particle interactions in the Lunar regolith. For low frequency experiments, such as NuMoon, the frequency dependent dispersive effect of the ionosphere is an important experimental concern as it reduces the pulse amplitude and subsequent chances of detection. We are continuing to investigate a new method to calibrate the dispersive effect of the ionosphere on lunar Cherenkov pulses via Faraday rotation measurements of the Moon's polarised emission combined with geomagnetic field models. We also extend this work to include radio imaging of the Lunar surface, which provides information on the physical and chemical properties of the lunar surface that may affect experimental strategies for the lunar Cherenkov technique.
