Description
The Pierre Auger Observatory is designed to study cosmic ray showers at the
highest energy using a hybrid approach by combining complementary detection
techniques to study the same phenomena. One of these detectors is the
Surface Detector Array, a regular array of 1660 water Cherenkov detectors
distributed in an area of ~3000 km^2.
The surface detector has a centralized, hierarchical event trigger
mechanism by which all stations send timing information to a dedicated
computer system programmed to search for spatial and temporal coincidences,
sending data requests to a relatively broad cluster of stations when one
such coincidence is found.
This work proposes an alternative event trigger system in which each
station searches for the candidate shower trigger condition, and presents the progress
on simulations, using the OMNeT++ network simulator, to verify that i) the proposed
event trigger system can detect events using the same criteria currently applied in Auger,
and ii) to study the minimum hardware requirements for a possible implementation.
