Cosmic Ray Muon Physics
Design, local manufacture, and field deployment of Nepal's first cosmic ray muon detector. Systematic altitude-gradient measurements from Terai (~150m) to Himalayan passes above 5,000m. Applications in atmospheric monitoring, glacier research, and educational resources.

Muon flux vs altitude — Nepal's gradient
Atmospheric depth decreases with altitude, increasing the cosmic ray muon flux. Nepal's gradient spans ~10× from sea level to summit — yet has never been systematically measured.
Theoretical model (atmospheric depth scaling). Green: HICS stations. Amber: planned transect. Uncertainty band ±15% sensor accuracy.
