Particle Physics with the Pierre Auger Observatory

Abstract

The Pierre Auger Observatory is the largest extensive air shower detector. Based on a hybrid system, this experiment measures the longitudinal shower development and the particles at the ground. This detection system allows the extraction of the p-air cross-section at energies much higher than the ones accessible by current colliders. It is also possible to test hadronic interaction models using correlations between different air shower observables, like the depth of shower maximum and the muon number at the ground and their fluctuations. Thanks to the low energy extension of the Pierre Auger Observatory, the muon deficit in air shower simulations can be addressed over almost three decades at the highest energies.

A Narrow Optical Pulse Emitter Based on LED: NOPELED

“…Many particle physics experiments and applications include optical sensors as detector elements [ 1 , 2 , 3 , 4 , 5 , 6 ]. The use of devices producing short pulses of light (rise-time < 5 ns) is of great help in these applications, as they could help with the qualification of the light sensors, the calibration of the detectors once in operation, trying to replicate or mimic the light produced by the particles to be detected, or, directly, providing the pulses of light needed to operate the system [ 7 , 8 , 9 , 10 , 11 ].…”
