Abstract:
As part of the upgrade of the Pierre Auger Observatory, known as AugerPrime, the Underground Muon Detector is being installed in the low-energy extension of the Surface Detector, allowing for a direct measurement of the muonic component of air showers produced by ultra-high-energy cosmic rays with energies between 10$^{16.8}$ and 10$^{19}$ eV.
The detector consists of an array of 30 m$^2$ plastic scintillator detectors buried 2.3 m underground near a water-Cherenkov detector.
Two modes of operation are implemented to achieve an extended dynamic range: the binary mode, conceived for low muon densities, and the calorimetric mode, designed for high muon densities.
In this contribution, we present the current status and improvements in the reconstruction and performance of this component of AugerPrime.
