Microwave Detection of Cosmic Ray Air Showers at the Pierre Auger Observatory, an R&D Effort
Year: 2012
Type: article
Abstract: The measurement of microwave emission from air showers initiated by ultra-high energy cosmic rays may open the possibility of developing a novel detection technique. This new technique possesses the advantage of the fluorescence detection technique -the reconstruction of the longitudinal shower profile -combined with a 100% duty cycle, minimal atmospheric attenuation and the use of low cost commercial equipment. Placing prototype detectors at the Auger site provides for coincidence detection of air showers using established methods, ultimately assessing the feasibility of detecting air showers through microwave radiation. Two complementary techniques are currently being pursued at the Pierre Auger Observatory. MIDAS (Microwave Detection of Air Showers), AMBER (Air-shower Microwave Bremsstrahlung Experimental Radiometer), and FDWave are prototypes for large imaging dish antennas. EASIER (Extensive Air Shower Identification using Electron Radiometer), the second technique, utilizes horn antennas located on each Auger Surface Detector station for detection of microwave emission. MIDAS is a self-triggering system while AMBER, FDWave and EASIER use the trigger from the Auger detectors to record the microwave emission. The development status and future plans for these measurements is reported.
