Muon Tracker

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
