论文摘要
在过去的十年中，基于GHz频率的分子Bremsstrahlung辐射（MBR），在过去的十年中，在过去的十年中进行了多项试图检测由超高能宇宙射线引起的广泛的空气淋浴（EAS）（EAS）。这些尝试导致仅检测到少数信号，它们都沿淋浴轴向前定向，因此暗示着源自与Cherenkov角接近GHz频率的地磁和AskAskaryan排放。在对Arena2022的贡献中，由于频率范围的连贯抑制MBR在碰撞速率以下，由于破坏性干扰影响了电子连续碰撞之间的光子发射幅度，因此缺乏事件的检测。地面上的光谱强度显示出低于实验设置灵敏度的几个数量级。因此，MBR不能被视为接下来几十年EAS的新检测技术的基础。得出这一结论的形式主义允许强调电离电子速度的两点相关函数的关键作用。这可以用于研究这些电离电子的重新辐射的强度，但受雷达发射器的传入相干波的通过。将提出一些提示。
Several attempts to detect extensive air showers (EAS) induced by ultra-high energy cosmic rays have been conducted in the last decade based on the molecular Bremsstrahlung radiation (MBR) at GHz frequencies from quasi-elastic collisions of ionisation electrons left in the atmosphere after the passage of the cascade of particles. These attempts have led to the detection of a handful of signals only, all of them forward-directed along the shower axis and hence suggestive of originating from geomagnetic and Askaryan emissions extending into GHz frequencies close to the Cherenkov angle. In this contribution to ARENA2022, the lack of detection of events is explained by the coherent suppression of the MBR in frequency ranges below the collision rate due to the destructive interference impacting the emission amplitude of photons between the successive collisions of the electrons. The spectral intensity at the ground level is shown to be several orders of magnitude below the sensitivity of experimental setups. Consequently the MBR cannot be seen as the basis of a new detection technique of EAS for the next decades. The formalism developed to get at this conclusion allowed the key role of the two-point correlation function of the ionisation electron velocities to be highlighted. This can serve to study the intensity of the re-radiation of these ionization electrons subject to the passage of an incoming coherent wave from a radar transmitter. Some hints on this will be presented.
