A homogeneous calorimeter is a type of particle detector where the entire volume is sensitive to particle interactions, allowing it to measure the energy of incoming particles with high precision. It is often used in high-energy physics experiments due to its ability to provide detailed information on electromagnetic and hadronic showers without the need for separate absorber and detector layers.
Collider detectors are complex devices used in particle physics to track and identify particles produced by collisions in accelerators, providing crucial data for understanding fundamental forces and particles. They consist of multiple layers designed to measure different properties of particles, such as momentum, energy, and charge, enabling scientists to reconstruct events and test theoretical models.
