Spark Chambers The spark chamber is based on the simple fact that if the voltage across two metal plates separated by a distance of a few centimeters is increased beyond a certain value, a breakdown in the form of sparking occurs. The spark chamber consists of a series of thin parallel plates spaced a few […]
Scintillation Counter and Ionization Chamber
Scintillation Counter A scintillation counter is very sensitive device used in nuclear physics for detection and measurement of high energy radiation. In principle, it is based on the fact that α-particles on striking a fluorescent material like zinc sulphide produce tiny flashes of light. These flashes are called scintillations and can be seen in the […]
