Cosmic Ray RF detection with the Astroneu array

30TH INTERNATIONAL COSMIC RAY CONFERENCE CODALEMA : A Cosmic Ray Radio Detection Array

Extensive air showers are associated with transient radio emission, which could provide a new mode of detection of UHECR with an important target volume and a high duty cycle. The Codalema experiment has been set up and is running in the Radio Observatory in Nancay, France, to investigate this possibility. The apparatus is composed of an antenna array overlapped by a ground particle array. A se...

Detection of the Rf Pulse Associated with Cosmic Ray Air Showers

A project to detect the radio-frequency pulse associated with extensive air showers of cosmic rays is described briefly. Prototype work is being performed at the CASA/MIA array in Utah, with the intention of designing equipment that can be used in conjunction with the Auger Giant Array proposal.

Time Delays in Cosmic Ray Propagation

Cosmic Rays (CR) travel at speeds essentially indistinguishable from the speed of light. However whilst travelling through magnetic fields, both regular and turbulent, they are delayed behind the light since they are usually charged particles and their paths are not linear. Those delays can be so long that they are an impediment to correctly identifying sources which may be variable in time. Fu...

Cosmic Ray Results from the IceTop Air Shower Array

IceTop, the surface component of the IceCube neutrino telescope at the South Pole, is an air-shower array which will finally consist of 160 ice Cherenkov tanks at 80 stations spread over an area of 1 km. Currently 40 stations are deployed and taking data. The detector is designed to cover the energy range above the knee up to about 10 eV and study the mass composition of primary cosmic rays. In...
