Description
miniTRASGO is a compact and cost-effective detector for secondary charged cosmic rays, designed for research in solar activity, cosmic ray modulation, and atmospheric physics. Utilizing Resistive Plate Chambers (RPCs), it ensures stable detection rates and high sensitivity, as demonstrated by the observation of Forbush Decreases in March and May 2024 at the Madrid station ($40.4^\circ\mathrm{N},\ 7\ \mathrm{GV}$), where the first operational miniTRASGO unit successfully measured these events despite its small active area of $0.1\ \mathrm{m^{2}}$.
With deployments in Warsaw, Puebla, and Monterrey by early 2025, miniTRASGO will expand coverage across latitudes ($52^\circ\mathrm{N},\ 19^\circ\mathrm{N},\ 25^\circ\mathrm{N}$) and cutoff rigidities ($2.5\ \mathrm{GV},\ 8.2\ \mathrm{GV},\ 8.5\ \mathrm{GV}$), forming a scalable global muon monitoring network, even though it can also complement NMDB stations, such as CaLMa, which is near the Madrid station.
Beyond flux monitoring, miniTRASGO enables angular-resolved studies of cosmic ray variations, geomagnetic effects, and solar modulation, reinforcing its role in multi-site research.
