It contains a thin wire electrode aligned along the central axis of a cylindrical metal tube filled with gas at low pressure.
It contains a thin wire electrode aligned along the central axis of a cylindrical metal tube filled with gas at low pressure. When a high-energy [*] particle enters the tube through a thin window at one end, some gas atoms are ionized, creating an avalanche of electrons that produces a current pulse, often connected to a speaker that clicks after every event. For 10 points—name this device used to detect radioactivity.
