General Project Information

The AMIGA project is an extension of the Auger Observatory, and has the objective of extend the range of detection of energies in more than one order of magnitude, to 1017eV, being its scientific objective the study of the transition zone (between 1017 and 1019 eV), from the galactic sources of cosmic rays to extragalactic sources. Is then a zone of immense astrophysical interest marking the beginning of the study of extragalactic sources, who at higher energies has allowed the dawn of a new type of astronomy, the astronomy of charged particles. To realize this detection, AMIGA will be compound by an infill of 85 pars of SDs (surface detectors) and BDs (buried detectors), 61 of these with a separation of 750m and the 24 remaining with a separation of 433m. The BDs will be constituted by 4 muons counters formed  by 64 scintillator bars, a PMT multi-pixel and electronic of acquisition who will work along with the surface detector (Cherenkov radiation detection in water). The muons counters will be buried approximately 2,5m underground to achieve the detection exclusively of the muonic component of the particle rain.

AMIGA is formed by an international collaboration,that includes Germany, Argentina, Spain, Italy, Mexico, and Poland.

 

ITeDA Participation in the Project

ITeDA is the creative institution of the project and is who makes the greatest contributions to it. ITeDA is currently working on these tasks: 1) Simulations – Data Acquisition - Reconstructions, 2) Scintillators Modules, 3) Photomultiplier – Pulses – Database, 4) Telecommunications, and 5) Design, Installation and Interconnection of the Electronic components.

In addition, the institute has laboratories and installations created to prove and characterize all modules and PMTs before installation to ensure everything is working correctly and have full knowledge of its parameters.
