1. Status and performance of the underground muon detector of the Pierre Auger ObservatoryA.M. Botti, Andrej Filipčič, Jon Paul Lundquist, Samo Stanič, Serguei Vorobiov, Danilo Zavrtanik, Marko Zavrtanik, Lukas Zehrer, 2022, objavljeni znanstveni prispevek na konferenci Opis: The Auger Muons and Infill for the Ground Array (AMIGA) is an enhancement of the Pierre Auger Observatory, whose purpose is to lower the energy threshold of the observatory down to 10^16.5 eV, and to measure the muonic content of air showers directly. These measurements will significantly contribute to the determination of primary particle masses in the range between the second knee and the ankle, to the study of hadronic interaction models with air showers, and, in turn, to the understanding of the muon puzzle. The underground muon detector of AMIGA is concomitant to two triangular grids of water-Cherenkov stations with spacings of 433 and 750 m; each grid position is equipped with a 30 m^2 plastic scintillator buried at 2.3 m depth. After the engineering array completion in early 2018 and general improvements to the design, the production phase commenced. In this work, we report on the status of the underground muon detector, the progress of its deployment, and the performance achieved after two years of operation. The detector construction is foreseen to finish by mid-2022.

4. The AMIGA Muon Counters of the Pierre Auger Observatory: Performance and Studies of the Lateral Distribution FunctionBrian Wundheiler, Andrej Filipčič, Gašper Kukec Mezek, Ahmed Saleh, Samo Stanič, Marta Trini, Darko Veberič, Serguei Vorobiov, Lili Yang, Danilo Zavrtanik, Marko Zavrtanik, 2015, objavljeni znanstveni prispevek na konferenci Opis: The AMIGA enhancement (Auger Muons and Infill for the Ground
Array) of the Pierre Auger Observatory consists of a 23.5 km2
infill area where air shower particles are sampled by water-
Cherenkov detectors at the surface and by 30 m2 scintillation
counters buried 2.3 m underground. The Engineering Array of
AMIGA, completed since February 2015, includes 37 scintillator
modules (290 m2) in a hexagonal layout. In this work, the muon
counting performance of the scintillation detectors is analysed
over the first 20 months of operation. Parametrisations of the
detector counting resolution and the lateral trigger
probability are presented. Finally, preliminary results on the observed muon lateral distribution function (LDF) are discussed.
