AntiMatter Matters upper level physics experiments

This positron annihilation and gamma-ray coincidence experiment system is designed to demonstrate the fundamental principles of antimatter, positron annihilation, and gamma-ray detection. It enables students to investigate time-coincidence techniques, study the production and annihilation of positrons, perform gamma-ray energy measurements, and understand the working principles of Positron Emission Tomography (PET). The system provides a complete laboratory platform for experiments in nuclear physics, radiation detection, and medical imaging. A digital oscilloscope is required for operation, while a multichannel analyzer is optional. Manufactured by Atico Export India.
