Detectors Based on Ionisation in Gases

Charged subatomic particles can be detected by their electromagnetic interactions with matter. Neutral subatomic particles can only be detected if they first undergo an interaction. The charged particles produced in the interaction reveal that a neutral particle was present. Today there are three main methods for detecting charged subatomic particles that are important in nuclear science or in high-energy physics: detection based on gas ionisation, detection based on semiconductors and detection based on scintillation. All these methods are based on the detection of electron ionisation or electron excitation produced by the coulomb interaction of the charged particle with the medium.
