photomultiplier tube
A photomultiplier tube is a highly sensitive electronic device used to detect and amplify very low levels of light, converting it into an electrical signal. It consists of a photocathode that emits electrons when struck by photons, which are then accelerated and multiplied through a series of dynodes, resulting in a significantly amplified output signal.
