A spark chamber is a device used to detect particles in particle physics research. It is essentially a gas-filled chamber with electrodes at different points inside it. When a charged particle passes through the chamber, it ionizes the gas, creating a path of ions that can be seen as sparks between the electrodes. The term spark chamber is sometimes used interchangeably with other words such as spark counter, spark detector, and spark tracker. These terms describe similar devices with the same basic function, but they may differ in the specific design and electronics used. Other related terms include time projection chamber (TPC) and drift chamber, which are more advanced forms of particle detectors that use more sophisticated techniques to track particles.
