2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/6062We report progress on applying technologies developed for LHC-era experiments to cosmic ray detection, using scintillating tiles with embedded wavelength-shifting fibers and avalanche photodiode readouts as parts of a robust, inexpensive cosmic air shower detector. We are planning to deploy such detectors in high schools as part of an outreach effort able to search for long-distance correlations between airshowers.To be published in the Proceedings of the 28th International Cosmic Ray Conference http://www.icrr.u-tokyo.ac.jp/icrc2003/Astrophysicstext
