A drift chamber is a type of particle detector used in high-energy physics experiments. It consists of a series of wires arranged in a gas-filled chamber. When charged particles pass through the chamber, they ionize the gas, creating electron-ion pairs. The electrons drift towards the wires, producing an electrical signal that can be measured. Drift chambers are often used in conjunction with other detectors, such as tracking detectors and calorimeters, to provide detailed information about the paths and energies of particles. They play a crucial role in experiments at particle accelerators like the Large Hadron Collider (LHC).
