Key concepts
- Multiwire Proportional Chamber (MWPC) — A gaseous detector that uses a parallel array of anode wires to detect ionization trails left by charged particles, providing precise spatial information.
- Drift Chamber — A gaseous detector where ionization electrons drift in a uniform electric field towards sense wires, allowing for precise determination of particle trajectories over larger volumes.
- Gas Gain — The amplification process within a gaseous detector where primary ionization electrons produce secondary electrons through collisions, increasing the signal strength.
- Spatial Resolution — The ability of a detector to distinguish between two closely spaced points or events, a key performance metric for particle tracking.
- Particle Tracking — The process of reconstructing the path of a charged particle through a detector by measuring its position at multiple points.
