Radio detection of neutrinos: How, where and why
The particles with the highest known energies in the universe are cosmic rays. Energies unreachable by human accelerators. But even after more than 100 years since their discovery, it is still unknown which astronomical objects can create such ultra-high energetic charged particles. Detecting ultra-high energy neutrinos may resolve the problem. Neutrinos travel in unimpeded in straight-lines, thereby revealing their sources, which they share with cosmic rays.
The optical detectors, mostly notably IceCube at the South Pole, have started the exciting field of neutrino astronomy. However, even these enormous detectors do not monitor enough ice be able to detect the small flux of neutrinos of the highest energies. I will elaborate why radio detectors provide enough sensitivity, what technological challenges were meet on the way and how we will build a large detector to discover cosmogenic neutrinos.
