South Pole无线电表面阵列的物理潜力(ARENA 2018)

Physics Potential of a Radio Surface Array at the South Pole (ARENA 2018)

Frank G. Schröder

摘要:

无线电天线的表面阵列将提高IceTop阵列的性能,并实现新的互补科学目标。首先,宇宙射线空气簇射的准确性将得到提高,因为无线电阵列提供了电磁分量的量热测量,并且对簇射最大值的位置很敏感。这种增强的精度可以用来更好地测量质量组成,寻找可能的质量依赖的各向异性的宇宙射线的到达方向,以及更彻底的测试强子相互作用模型。其次,射电阵列对倾斜阵雨的敏感性将增加宇宙射线测量的天空覆盖范围。第三,无线电阵列可以用来搜索来自银河系中心的PeV光子。由于IceTop计划在不久的将来通过闪烁体阵列进行增强,因此可以安装共享相同基础设施的无线电扩展,只需最小的额外努力和良好的科学前景。冰立方的冰-切伦科夫、闪烁和无线电探测器的组合将为高能银河宇宙射线的研究提供前所未有的精确度。

英文摘要:

A surface array of radio antennas will enhance the performance of the IceTop array and enable new, complementary science goals. First, the accuracy for cosmic-ray air showers will be increased since the radio array provides a calorimetric measurement of the electromagnetic component and is sensitive to the position of the shower maximum. This enhanced accuracy can be used to better measure the mass composition, to search for possible mass-dependent anisotropies in the arrival directions of cosmic rays, and for more thorough tests of hadronic interaction models. Second, the sensitivity of the radio array to inclined showers will increase the sky coverage for cosmic-ray measurements. Third, the radio array can be used to search for PeV photons from the Galactic Center. Since IceTop is planned to be enhanced by a scintillator array in the near future, a radio extension sharing the same infrastructure can be installed with minimal additional effort and excellent scientific prospects. The combination of ice-Cherenkov, scintillation, and radio detectors at IceCube will provide unprecedented accuracy for the study of highenergy Galactic cosmic rays.
