Abstract: Cosmic rays are high-energy particles originating from space that interact with Earth's atmosphere, producing secondary particles such as muons, electrons, and positrons. Detecting these particles provides insights into high-energy astrophysics, fundamental physics, and atmospheric interactions. The cloud chamber, a classical particle detector, is widely used for visualizing cosmic ray interactions; however, it has limitations in charge differentiation, track resolution, and statistical validation. This study presents an improved cloud chamber setup with enhanced cooling, optimized lighting, and high-speed imaging for better track visibility. A magnetic field is implemented to distinguish electrons from positrons based on curvature. Additionally, cosmic ray flux measurements are conducted at varying altitudes (0m–2000m) to analyze atmospheric interactions. Advanced statistical modeling, including Pearson correlation, Poisson distributions, and exponential regression, is applied to validate the data. Results confirm that muon flux increases exponentially with altitude, while the magnetic field effectively differentiates between electrons and positrons. This study establishes a cost-effective, scalable framework for cosmic ray research, making it suitable for both laboratory and field experiments.
