The photomultiplier tube and NaI (sodium iodide) scintillator combination is one of the most common techniques for radiation measurement. Photomultiplier tubes with a semi-transparent photocathode are widely used since their sensitivity matches the emission spectrum of NaI scintillators near the 420 nm light wavelength. Some semi-transparent ...
Photomultiplier tubes (PMTs) are sensitive detectors used to measure very low levels of light. They are widely used in many fields, including medical imaging, nuclear and particle physics, and astronomy. PMTs are capable of detecting single photons and can amplify the signal by many orders of magnitude, making them extremely useful …
