摘要：The lunar Cherenkov technique is a method to detect ultra-high-energy (UHE) cosmic-rays and neutrinos with Earth-based radio-telescopes. When an UHE particle hits the Moon, it initiates a hadronic cascade below the surface. The cascade has a negative charge excess that propagates faster than the local speed of light in the medium, producing a short pulse of radio Cherenkov emission. The NuMoon project aims to detect these lunar radio pulses on Earth with lowfrequency radio telescopes. In the first phase a measurement was performed with the Westerbork Synthesis Radio Telescope array, resulting in an upper limit on the neutrino flux an order of magnitude better than previous existing limits. We are currently preparing to perform this measurement with LOFAR. The expected sensitivity of LOFAR reaches flux limits within the range of some theoretical production models. With SKA it should be possible to detect neutrinos that are the decay products of pions produced in the interaction of UHE cosmic particles with the cosmic microwave background (GZK neutrinos).
