Muon Tracker brings the fascinating phenomenon of muon detection right to your device. Designed for science enthusiasts, students, and educators, this app simulates the detection of high-energy muons—particles created when cosmic rays collide with the upper atmosphere—and visualizes them in real time. What it does • Simulates the arrival of cosmic muons based on your current location (latitude, longitude, and altitude). • Accurately models muon flux and angular distribution, including diurnal and seasonal variations. • Detects and visualizes muon tracks with animated directional paths, energy estimates, and impact points on your screen. • Displays real-time rates and calculated flux in particles per second and per square meter. • Offers a data panel where you can explore and export historical events with timestamps, angles, and energy in GeV. Scientific accuracy - Muon Tracker is powered by a physics-based simulation engine that factors in: • Atmospheric depth modeling to vary muon rates with elevation • Geomagnetic latitude effects to reflect regional muon flux • Angular dependency using a cosine-squared distribution to simulate slant tracks • Randomized yet statistically valid energy distributions typical of atmospheric muons The simulation mimics real-world detection environments scaled to your device’s screen size. Whether you’re at sea level or on a mountain, the simulated flux adjusts accordingly. Ideal for • Physics students learning about particle physics and cosmic radiation • Educators demonstrating subatomic phenomena in classrooms • Science fans and curious minds exploring the universe from their pocket Features • Intuitive and elegant SwiftUI interface • Toggle between persistence mode (trails) and flash mode (instant hits) • Auto-switch between track visualization and point hits based on device orientation (vertical ↔ horizontal) • Muon tracks rendered in 3D space, dynamically responsive to device rotation • View location-based detection stats, including GPS position and altitude • Adjust altitude manually to observe its effect on muon flux • Real-time log of muon events, including incidence angle and particle energy • Plot angular distribution of muon track directions • Export your event log as a CSV file for deeper analysis • Works fully offline, with smart location-based initialization Step into the invisible universe. Download Muon Tracker and detect the particles that travel from space through you every second.
