Spark chamber

A Spark Chamber is a device used in physics to detect charged particles, like those from space or atomic reactions. It contains a gas-filled chamber with electrodes that create an electric field. When a charged particle passes through, it ionizes the gas, causing a localized electrical discharge or spark along its path. This spark makes the particle's track visible, allowing scientists to observe its trajectory. Spark chambers were historically important in particle physics research, helping to analyze the behavior and properties of subatomic particles.
