Antimatter: Antimatter refers to particles that are similar to ordinary matter particles but carry opposite charges (e.g., positrons instead of electrons).
Particle Accelerator: A particle accelerator is a scientific device used to accelerate charged particles, including positrons, to high speeds for various research purposes.
Annihilation: Annihilation is the process in which a particle and its antiparticle collide and convert their mass into energy, resulting in their mutual destruction.
