Spark chambers consists of metal plates placed in a sealed box filled with a gas such as [[helium]], [[neon]] or a mixture of the two. As a charged particle travels through the detector, it will [[ion]]ize the gas between the plates. A trigger system is used to apply high [[voltage]] to the plates to create an [[electric field]] immediately after the particle goes through the chamber, producing sparks on its exact trajectory.
