概要	Geant4 is a Monte Carlo simulation toolkit for the passage of particles through matter, developed by an international collaboration. It provides a comprehensive framework for modeling detector geometries, simulating particle interactions, and predicting detector responses, making it essential for designing and optimizing particle physics experiments.	The Particle-in-Cell (PIC) method is a powerful computational technique for simulating the dynamics of charged particle beams and plasmas in complex electromagnetic field configurations. By tracking individual macroparticles and self-consistently solving Maxwell's equations on a grid, PIC enables study of collective effects and nonlinear phenomena in beam and accelerator physics.
