Detection of Cosmic-Ray Ensembles with CREDO

Cosmic Ray Muon Detection

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...

High Altitude Cosmic Ray Radiation Detection

Earth’s atmosphere is constantly being bombarded with cosmic rays. However, the origin and effect of this radiation is relatively unknown. We report on the results of a payload that was launched on the balloon sat EOSS flight 201 under the fall DemoSAT program for the COSGC. The payload was designed to measure these cosmic rays using an onboard geiger counter. These results are intended to be u...

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...
