Radomir Smida (Karlsruhe Institute of Technology)21/06/2012, 15:10Specialised TalkThe CROME experiment is a new setup to study microwave radiation from air showers. The GHz radiation is measured with several parabolic antennas, each equipped with a multiple-receiver camera operating in the extended C band (3.4--4.2 GHz). Data are taken in coincidence with cosmic-ray showers detected by the KASCADE-Grande experiment. The overall experimental setup will be presented and...Go to contribution page

Felix Werner (Karlsruhe Institute of Technology)21/06/2012, 15:30Specialised TalkMicrowave radiation from high-energy air showers has been observed in the C band with the CROME setup. The properties of these showers as reconstructed by KASCADE-Grande will be presented. The features of the detected GHz signals will be discussed and compared with Monte Carlo predictions for different emission mechanisms, taking into account the reconstruction uncertainties of KASCADE-Grande.Go to contribution page

Sebastian Mathys (Bergische Universität Wuppertal)21/06/2012, 15:50Specialised TalkExtensive air showers are detected via particle measurements on the ground, the energy deposition in the atmosphere or via MHz-radio waves produced mainly by charged particles moving in the magnetic field of the earth. In addition, emission is predicted due to molecular bremsstrahlung. The Cosmic-Ray Observation via Microwave Emission (CROME) setup at the Karlsruhe Institute of Technology...Go to contribution page

Pedro Facal San Luis (University of Chicago)21/06/2012, 16:40Specialised TalkRadiation in the microwave band from the passage of charged particles has been measured in accelerator test beams. This radiation could provide a new technique for ultra-high energy cosmic rays, its main advantage being the possibility to instrument a large area, with 100% duty cycle and virtually no atmospheric attenuation, using relatively cheap equipment. Cosmic ray detection in the GHz...Go to contribution page

Mr Tokonatsu Yamamoto (Konan University)21/06/2012, 17:00Specialised TalkAn observation system of MBR from extensive airshowers is being developed on a roof of the Konan University in Japan. This system consists of 12 parabolas with 1.2 diameters. Each parabola has a 12 GHz receiver. The signals from the receivers are digitized by 65 MS/s FADC. Field of view of each parabola is about 1.5 degrees and this system covers 6 times 4.5 square degrees. Test observation...Go to contribution page

Pedro Facal San Luis (University of Chicago)21/06/2012, 17:20Specialised TalkThe MAYBE (Microwave Air Yield Beam) Experiment is dedicated to the study of the microwave emission from particle beams in the light of its possible use in the detection of ultra high energy cosmic rays. Measurements of the microwave emission from an electron-beam where performed at the 3 MeV electron Van de Graaff facility of the Argonne National Laboratory. Results include the measured...Go to contribution page

Dr Konstantin Belov (UCLA)21/06/2012, 17:40Specialised TalkThe Antarctic Impulsive Transient Antenna (ANITA) is a balloon-borne radio experiment designed to discover ultra-high energy cosmic neutrinos. The ANITA detector has completed one prototype and two full-scale flights above the Antarctic continent. Two direct and fourteen reflected cosmic ray events of the ultra-high energy were observed during the first full scale flight and several others in...Go to contribution page
