A Search for Point Sources of Cosmic Primary Rays Which Produce Single Muon Tracks at Ground Level

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/1545An increased data sample of identified secondary muons is collected at detection level. Project GRAND identifies secondary cosmic ray muons from electrons utilizing a thin steel absorber and tracking (PWC) chambers. The resulting angular resolution for the primary is about +/- 5 degrees. Since there is a 1.5% probability that a 100 GeV gamma primary will produce a single muon track at ground level, the high statistics allows a search for angular enhancements due to gammas. More than 100 billion muons are identified and analyzed. A table of stellar sources is examined.4 pgs; includes 1 fig. and 2 tables.
