Outdoor Systems Performace and Upgrade
L. Lopes, S. Andringa, P. Assis +17
Over the last two decades, the possibility of using RPCs in outdoors systems has increased considerably. Our group has participated in this effort having installed several systems…
MARTA: A high-energy cosmic-ray detector concept with high-accuracy muon measurement
P. Abreu, S. Andringa, P. Assis +42
A new concept for the direct measurement of muons in air showers is presented. The concept is based on resistive plate chambers (RPCs), which can directly measure muons with very g…
Outdoor Field Experience with Autonomous RPC Based Stations
L. Lopes, P. Assis, A. Blanco +12
In the last two decades Resistive Plate Chambers were employed in the Cosmic Ray Experiments COVER-PLASTEX and ARGO/YBJ. In both experiments the detectors were housed indoors, like…
Nanosecond-level time synchronization of autonomous radio detector stations for extensive air showers
The Pierre Auger Collaboration, A. Aab, P. Abreu +448
To exploit the full potential of radio measurements of cosmic-ray air showers at MHz frequencies, a detector timing synchronization within 1 ns is needed. Large distributed radio d…
