👉 The detector fluid, often referred to as the scintillation or photomultiplier tube fluid in certain applications, is a critical component in particle detectors used to identify and measure subatomic particles. This fluid is typically a mixture of organic compounds that emit light when struck by ionizing radiation, such as photons or charged particles. When radiation interacts with the fluid, it excites the molecules, causing them to emit photons of light. These emitted photons are then detected by photodetectors, like photomultiplier tubes or silicon photomultipliers, which convert the light signals into electrical signals that can be processed and analyzed. The fluid's properties, such as its density and chemical composition, are carefully engineered to optimize the detection efficiency and minimize background noise, ensuring accurate and reliable particle identification.
